S
un Microsystems, Inc. was a company that sold computers, computer components, computer software, and information technology services and that created the Java programming language and the Network File System (NFS). Sun significantly evolved several key computing technologies, among them Unix, RISC processors, thin client computing, and virtualized computing. Sun was founded on February 24, 1982.[3] At its height, Sun headquarters were in Santa Clara, California (part of Silicon Valley), on the former west campus of the Agnews Developmental Center.

On January 27, 2010, Sun was acquired by Oracle Corporation for US $7.4 billion, based on an agreement signed on April 20, 2009.[4] The following month, Sun Microsystems, Inc. was merged with Oracle USA, Inc. to become Oracle America, Inc.[5]

Sun products included computer servers and workstations built on its own RISC-based SPARC processor architecture as well as on x86-based AMD's Opteron and Intel's Xeon processors; storage systems; and a suite of software products including the Solaris operating system, developer tools, Web infrastructure software, and identity management applications. Other technologies include the Java platform, MySQL, and NFS. Sun was a proponent of open systems in general and Unix in particular, and a major contributor to open source software.[6] Sun's main manufacturing facilities were located in Hillsboro, Oregon, and Linlithgow, Scotland.

The initial design for what became Sun's first Unix workstation, the Sun-1, was conceived by Andy Bechtolsheim when he was a graduate student at Stanford University in Palo Alto, California. Bechtolsheim originally designed the SUN workstation for the Stanford University Network communications project as a personal CAD workstation. It was designed around the Motorola 68000 processor with an advanced memory management unit (MMU) to support the Unix operating system with virtual memory support.[7] He built the first ones from spare parts obtained from Stanford's Department of Computer Science and Silicon Valley supply houses.[8]

On February 24, 1982, Vinod Khosla, Andy Bechtolsheim, and Scott McNealy, all Stanford graduate students, founded Sun Microsystems. Bill Joy of Berkeley, a primary developer of the Berkeley Software Distribution (BSD), joined soon after and is counted as one of the original founders.[9] The Sun name is derived from the initials of the Stanford University Network.[10][11][12] Sun was profitable from its first quarter in July 1982.

By 1983 Sun was known for producing 68000-based systems with high-quality graphics that were the only computers other than DEC's VAX to run 4.2BSD. It licensed the computer design to other manufacturers, which typically used it to build Multibus-based systems running Unix from UniSoft.[13] Sun's initial public offering was in 1986 under the stock symbol SUNW, for Sun Workstations (later Sun Worldwide).[14][15] The symbol was changed in 2007 to JAVA; Sun stated that the brand awareness associated with its Java platform better represented the company's current strategy.[16]

Sun's logo, which features four interleaved copies of the word sun, was designed by professor Vaughan Pratt, also of Stanford. The initial version of the logo was orange and had the sides oriented horizontally and vertically, but it was subsequently rotated to stand on one corner and re-colored purple, and later blue.

The "Bubble" and its aftermath

In the dot-com bubble, Sun began making much more money, and its shares rose dramatically. It also began spending much more, hiring workers and building itself out. Some of this was because of genuine demand, but much was from web start-up companies anticipating business that would never happen. In 2000, the bubble burst.[17] Sales in Sun's important hardware division went into free-fall as customers closed shop and auctioned off high-end servers.

Several quarters of steep losses led to executive departures, rounds of layoffs,[18][19][20] and other cost cutting. In December 2001, the stock fell to the 1998, pre-bubble level of about $100. But it kept falling, faster than many other tech companies. A year later it had dipped below $10 (a tenth of what it was even in 1990) but bounced back to $20. In mid-2004, Sun closed their Newark, California factory and consolidated all manufacturing to Hillsboro, Oregon.[21] In 2006, that factory also closed.[22]

Post-crash focus

In 2004, Sun canceled two major processor projects which emphasized high instruction level parallelism and operating frequency. Instead, the company chose to concentrate on processors optimized for multi-threading and multiprocessing, such as the UltraSPARC T1 processor (codenamed "Niagara"). The company also announced a collaboration with Fujitsu to use the Japanese company's processor chips in mid-range and high-end Sun servers. These servers were announced on April 17, 2007 as the M-Series, part of the SPARC Enterprise series.

In February 2005, Sun announced the Sun Grid, a grid computing deployment on which it offered utility computing services priced at US$1 per CPU/hour for processing and per GB/month for storage. This offering built upon an existing 3,000-CPU server farm used for internal R&D for over 10 years, which Sun marketed as being able to achieve 97% utilization. In August 2005, the first commercial use of this grid was announced for financial risk simulations which was later launched as its first software as a service product.[23]

In January 2005, Sun reported a net profit of $19 million for fiscal 2005 second quarter, for the first time in three years. This was followed by net loss of $9 million on GAAP basis for the third quarter 2005, as reported on April 14, 2005. In January 2007, Sun reported a net GAAP profit of $126 million on revenue of $3.337 billion for its fiscal second quarter. Shortly following that news, it was announced that Kohlberg Kravis Roberts (KKR) would invest $700 million in the company.[24]

Sun had engineering groups in Bangalore, Beijing, Dublin, Grenoble, Hamburg, Prague, St. Petersburg, Tel Aviv, Tokyo, and Trondheim.[25]

In 2007–2008, Sun posted revenue of $13.8 billion and had $2 billion in cash. First-quarter 2008 losses were $1.68 billion; revenue fell 7% to $12.99 billion. Sun's stock lost 80% of its value November 2007 to November 2008, reducing the company's market value to $3 billion. With falling sales to large corporate clients, Sun announced plans to lay off 5,000 to 6,000 workers, or 15–18% of its work force. It expected to save $700 million to $800 million a year as a result of the moves, while also taking up to $600 million in charges.[26]

Hardware

For the first decade of Sun's history, the company positioned its products as technical workstations, competing successfully as a low-cost vendor during the Workstation Wars of the 1980s. It then shifted its hardware product line to emphasize servers and storage. High-level telecom control systems such as Operational Support Systems service predominantly used Sun equipment. This use is due mainly to the company basing its products around a mature and very stable version of the Unix operating system and the support service that Sun provides.[citation needed]

Motorola-based systems

Sun originally used Motorola 68000 family central processing units for the Sun-1 through Sun-3 computer series. The Sun-1 employed a 68000 CPU, the Sun-2 series, a 68010. The Sun-3 series was based on the 68020, with the later Sun-3x using the 68030.[67]

SPARC-based systems

SPARCstation 1+

In 1987, the company began using SPARC, a RISC processor architecture of its own design, in its computer systems, starting with the Sun-4 line. SPARC was initially a 32-bit architecture (SPARC V7) until the introduction of the SPARC V9 architecture in 1995, which added 64-bit extensions.
Sun has developed several generations of SPARC-based computer systems, including the SPARCstation, Ultra and Sun Blade series of workstations, and the SPARCserver, Netra, Enterprise and Sun Fire line of servers.

In the early 1990s the company began to extend its product line to include large-scale symmetric multiprocessing servers, starting with the four-processor SPARCserver 600MP. This was followed by the 8-processor SPARCserver 1000 and 20-processor SPARCcenter 2000, which were based on work done in conjunction with Xerox PARC. In 1995 the company introduced Sun Ultra series machines that were equipped with the first 64-bit implementation of SPARC processors (UltraSPARC). In the late 1990s the transformation of product line in favor of large 64-bit SMP systems was accelerated by the acquisition of Cray Business Systems Division from Silicon Graphics.[32] Their 32-bit, 64-processor Cray Superserver 6400, related to the SPARCcenter, led to the 64-bit Sun Enterprise 10000 high-end server (otherwise known as Starfire).

In September 2004 Sun made available systems with UltraSPARC IV[68] which was the first multi-core SPARC processor. It was followed by UltraSPARC IV+ in September 2005[69] and its revisions with higher clock speeds in 2007.[70] These CPUs were used in the most powerful, enterprise class high-end CC-NUMA servers developed by Sun, such as Sun Fire E25K.

In November 2005 Sun launched the UltraSPARC T1, notable for its ability to concurrently run 32 threads of execution on 8 processor cores. Its intent was to drive more efficient use of CPU resources, which is of particular importance in data centers, where there is an increasing need to reduce power and air conditioning demands, much of which comes from the heat generated by CPUs. The T1 was followed in 2007 by the UltraSPARC T2, which extended the number of threads per core from 4 to 8. Sun has open sourced the design specifications of both the T1 and T2 processors via the OpenSPARC project.

In 2006, Sun has also ventured into the blade server (high density rack-mounted systems) market with the Sun Blade (distinct from the Sun Blade workstation).

In April 2007 Sun released the SPARC Enterprise server products, jointly designed by Sun and Fujitsu and based on Fujitsu SPARC64 VI and later processors. The M-class SPARC Enterprise systems include high-end reliability and availability features. Later T-series servers have also been badged SPARC Enterprise rather than Sun Fire.

In April 2008 Sun released servers with UltraSPARC T2 Plus, which is an SMP capable version of UltraSPARC T2, available in 2 or 4 processor configurations. It was the first CoolThreads CPU with multi-processor capability and it made possible to build standard rack-mounted servers that could simultaneously process up to massive 256 CPU threads in hardware (Sun SPARC Enterprise T5440),[71][72] which is considered a record in the industry.

Since 2010, all further development of Sun machines based on SPARC architecture (including new SPARC T-Series servers, SPARC T3 and T4 chips) is done as a part of Oracle Corporation hardware division.

x86-based systems

In the late 1980s, Sun also marketed an Intel 80386-based machine, the Sun386i; this was designed to be a hybrid system, running SunOS but at the same time supporting DOS applications. This only remained on the market for a brief time. A follow-up "486i" upgrade was announced but only a few prototype units were ever manufactured.

Sun's brief first foray into x86 systems ended in the early 1990s, as it decided to concentrate on SPARC and retire the last Motorola systems and 386i products, a move dubbed by McNealy as "all the wood behind one arrowhead". Even so, Sun kept its hand in the x86 world, as a release of Solaris for PC compatibles began shipping in 1993.

In 1997 Sun acquired Diba, Inc., followed later by the acquisition of Cobalt Networks in 2000, with the aim of building network appliances (single function computers meant for consumers). Sun also marketed a network computer (a term popularized and eventually trademarked by Oracle); the JavaStation was a diskless system designed to run Java applications.

Although none of these business initiatives were particularly successful, the Cobalt purchase gave Sun a toehold for its return to the x86 hardware market. In 2002, Sun introduced its first general purpose x86 system, the LX50, based in part on previous Cobalt system expertise. This was also Sun's first system announced to support Linux as well as Solaris.

In 2003, Sun announced a strategic alliance with AMD to produce x86/x64 servers based on AMD's Opteron processor; this was followed shortly by Sun's acquisition of Kealia, a startup founded by original Sun founder Andy Bechtolsheim, which had been focusing on high-performance AMD-based servers.

The following year, Sun launched the Opteron-based Sun Fire V20z and V40z servers, and the Java Workstation W1100z and W2100z workstations.

On September 12, 2005, Sun unveiled a new range of Opteron-based servers: the Sun Fire X2100, X4100 and X4200 servers.[73] These were designed from scratch by a team led by Bechtolsheim to address heat and power consumption issues commonly faced in data centers. In July 2006, the Sun Fire X4500 and X4600 systems were introduced, extending a line of x64 systems that support not only Solaris, but also Linux and Microsoft Windows.

On January 22, 2007, Sun announced a broad strategic alliance with Intel.[74] Intel endorsed Solaris as a mainstream operating system and as its mission critical Unix for its Xeon processor-based systems, and contributed engineering resources to OpenSolaris.[75] Sun began using the Intel Xeon processor in its x64 server line, starting with the Sun Blade X6250 server module introduced in June 2007.

On May 5, 2008, AMD announced its Operating System Research Center (OSRC) expanded its focus to include optimization to Sun's OpenSolaris and xVM virtualization products for AMD based processors.[76]

Software

Although Sun was initially known as a hardware company, its software history began with its founding in 1982; co-founder Bill Joy was one of the leading Unix developers of the time, having contributed the vi editor, the C shell, and significant work developing TCP/IP and the BSD Unix OS. Sun later developed software such as the Java programming language and acquired software such as StarOffice, VirtualBox and MySQL.

Sun used community-based and open-source licensing of its major technologies, and for its support of its products with other open source technologies. GNOME-based desktop software called Java Desktop System (originally code-named "Madhatter") was first distributed as a Linux implementation then offered as part of the Solaris operating system. Sun supported its Java Enterprise System (a middleware stack) on Linux. It released the source code for Solaris under the open-source Common Development and Distribution License, via the OpenSolaris community. Sun's positioning includes a commitment to indemnify users of some software from intellectual property disputes concerning that software. It offers support services on a variety of pricing bases, including per-employee and per-socket.

A 2006 report prepared for the EU by UNU-MERIT stated that Sun was the largest corporate contributor to open source movements in the world.[77] According to this report, Sun's open source contributions exceed the combined total of the next five largest commercial contributors.

Operating systems

Sun is best known for its Unix systems, which have a reputation for system stability and a consistent design philosophy.
Sun's first workstation shipped with UniSoft V7 Unix. Later in 1982 Sun began providing SunOS, a customized 4.1BSD Unix, as the operating system for its workstations.[citation needed]

In the late 1980s, AT&T tapped Sun to help them develop the next release of their branded UNIX, and in 1988 announced they would purchase up to a 20% stake in Sun.[78] UNIX System V Release 4 (SVR4) was jointly developed by AT&T and Sun; Sun used SVR4 as the foundation for Solaris 2.x, which became the successor to SunOS 4.1.x (later retrospectively named Solaris 1.x). By the mid-1990s, the ensuing Unix wars had largely subsided, AT&T had sold off their Unix interests, and the relationship between the two companies was significantly reduced.

From 1992 Sun also sold Interactive Unix, an operating system it acquired when it bought Interactive Systems Corporation from Eastman Kodak Company. This was a popular Unix variant for the PC platform and a major competitor to market leader SCO UNIX. Sun's focus on Interactive Unix diminished in favor of Solaris on both SPARC and x86 systems; it was dropped as a product in 2001.[citation needed]

Sun dropped the Solaris 2.x version numbering scheme after the Solaris 2.6 release (1997); the following version was branded Solaris 7. This was the first 64-bit release, intended for the new UltraSPARC CPUs based on the SPARC V9 architecture. Within the next four years, the successors Solaris 8 and Solaris 9 were released in 2000 and 2002 respectively.

Following several years of difficult competition and loss of server market share to competitors' Linux-based systems, Sun began to include Linux as part of its strategy in 2002. Sun supported both Red Hat Enterprise Linux and SUSE Linux Enterprise Server on its x64 systems; companies such as Canonical Ltd., Wind River Systems and MontaVista also supported their versions of Linux on Sun's SPARC-based systems.

In 2004, after having cultivated a reputation as one of Microsoft's most vocal antagonists, Sun entered into a joint relationship with them, resolving various legal entanglements between the two companies and receiving US$1.95 billion in settlement payments from them.[79] Sun supported Microsoft Windows on its x64 systems, and announced other collaborative agreements with Microsoft, including plans to support each other's virtualization environments.[80]

In 2005, the company released Solaris 10. The new version included a large number of enhancements to the operating system, as well as very novel features, previously unseen in the industry. Solaris 10 update releases continued through the next 8 years, the last release from Sun Microsystems being Solaris 10 10/09. The following updates were released by Oracle under the new license agreement; the final release is Solaris 10 1/13.[81]

Previously, Sun offered a separate variant of Solaris called Trusted Solaris, which included augmented security features such as multilevel security and a least privilege access model. Solaris 10 included many of the same capabilities as Trusted Solaris at the time of its initial release; Solaris 10 11/06 included Solaris Trusted Extensions, which give it the remaining capabilities needed to make it the functional successor to Trusted Solaris.

Following acquisition of Sun, Oracle Corporation continued to develop Solaris operating system, and released Oracle Solaris 11 in November 2011.

Java platform

The Java platform was developed at Sun in the early 1990s with the objective of allowing programs to function regardless of the device they were used on, sparking the slogan "Write once, run anywhere" (WORA). While this objective was not entirely achieved (prompting the riposte "Write once, debug everywhere"), Java is regarded as being largely hardware- and operating system-independent.
Java was initially promoted as a platform for client-side applets running inside web browsers. Early examples of Java applications were the HotJava web browser and the HotJava Views suite. However, since then Java has been more successful on the server side of the Internet.

The platform consists of three major parts: the Java programming language, the Java Virtual Machine (JVM), and several Java Application Programming Interfaces (APIs). The design of the Java platform is controlled by the vendor and user community through the Java Community Process (JCP).

Java is an object-oriented programming language. Since its introduction in late 1995, it became one of the world's most popular programming languages.[82]

Java programs are compiled to byte code, which can be executed by any JVM, regardless of the environment.

The Java APIs provide an extensive set of library routines. These APIs evolved into the Standard Edition (Java SE), which provides basic infrastructure and GUI functionality; the Enterprise Edition (Java EE), aimed at large software companies implementing enterprise-class application servers; and the Micro Edition (Java ME), used to build software for devices with limited resources, such as mobile devices.

On November 13, 2006, Sun announced it would be licensing its Java implementation under the GNU General Public License; it released its Java compiler and JVM at that time.[83]

In February 2009 Sun entered a battle with Microsoft and Adobe Systems, which promoted rival platforms to build software applications for the Internet.[84] JavaFX was a development platform for music, video and other applications that builds on the Java programming language.[84]

Office suite

In 1999, Sun acquired the German software company StarDivision and with it the office suite StarOffice, which Sun later released as OpenOffice.org under both GNU LGPL and the SISSL (Sun Industry Standards Source License). OpenOffice.org supported Microsoft Office file formats (though not perfectly), was available on many platforms (primarily Linux, Microsoft Windows, Mac OS X, and Solaris) and was used in the open source community.

The principal differences between StarOffice and OpenOffice.org were that StarOffice was supported by Sun, was available as either a single-user retail box kit or as per-user blocks of licensing for the enterprise, and included a wider range of fonts and document templates and a commercial quality spellchecker.[85] StarOffice also contained commercially licensed functions and add-ons; in OpenOffice.org these were either replaced by open-source or free variants, or are not present at all. Both packages had native support for the OpenDocument format.

Virtualization and datacenter automation software


VirtualBox, purchased by Sun

In 2007, Sun announced the Sun xVM virtualization and datacenter automation product suite for commodity hardware. Sun also acquired VirtualBox in 2008. Earlier virtualization technologies from Sun like Dynamic System Domains and Dynamic Reconfiguration were specifically designed for high-end SPARC servers, and Logical Domains only supports the UltraSPARC T1/T2/T2 Plus server platforms. Sun marketed Sun Ops Center provisioning software for datacenter automation.

On the client side, Sun offered virtual desktop solutions. Desktop environments and applications could be hosted in a datacenter, with users accessing these environments from a wide range of client devices, including Microsoft Windows PCs, Sun Ray virtual display clients, Apple Macintoshes, PDAs or any combination of supported devices. A variety of networks were supported, from LAN to WAN or the public Internet. Virtual desktop products included Sun Ray Server Software, Sun Secure Global Desktop and Sun Virtual Desktop Infrastructure.

Database management systems

Sun acquired MySQL AB, the developer of the MySQL database in 2008 for US$1 billion.[86] CEO Jonathan Schwartz mentioned in his blog that optimizing the performance of MySQL was one of the priorities of the acquisition.[87] In February 2008, Sun began to publish results of the MySQL performance optimization work.[88] Sun contributed to the PostgreSQL project. On the Java platform, Sun contributed to and supported Java DB.

Other software

Sun offered other software products for software development and infrastructure services. Many were developed in house; others came from acquisitions, including Tarantella, Waveset Technologies,[50] SeeBeyond, and Vaau. Sun acquired many of the Netscape non-browser software products as part a deal involving Netscape's merger with AOL.[89] These software products were initially offered under the "iPlanet" brand; once the Sun-Netscape alliance ended, they were re-branded as "Sun ONE" (Sun Open Network Environment), and then the "Sun Java System".

Sun's middleware product was branded as the Java Enterprise System (or JES), and marketed for web and application serving, communication, calendaring, directory, identity management and service-oriented architecture. Sun's Open ESB and other software suites were available free of charge on systems running Solaris, Red Hat Enterprise Linux, HP-UX, and Windows, with support available optionally.

Sun developed data center management software products, which included the Solaris Cluster high availability software, and a grid management package called Sun Grid Engine and firewall software such as SunScreen. For Network Equipment Providers and telecommunications customers, Sun developed the Sun Netra High-Availability Suite.

Sun produced compilers and development tools under the Sun Studio brand, for building and developing Solaris and Linux applications. Sun entered the software as a service (SaaS) market with zembly, a social cloud-based computing platform and Project Kenai, an open-source project hosting service.

Storage

Sun sold its own storage systems to complement its system offerings; it has also made several storage-related acquisitions. On June 2, 2005, Sun announced it would purchase Storage Technology Corporation (StorageTek) for US$4.1 billion in cash, or $37.00 per share, a deal completed in August 2005.

In 2006, Sun introduced the Sun StorageTek 5800 System, the first application-aware programmable storage solution. In 2008, Sun contributed the source code of the StorageTek 5800 System under the BSD license.[90]

Sun announced the Sun Open Storage platform in 2008 built with open source technologies. In late 2008 Sun announced the Sun Storage 7000 Unified Storage systems (codenamed Amber Road). Transparent placement of data in the systems' solid-state drives (SSD) and conventional hard drives was managed by ZFS to take advantage of the speed of SSDs and the economy of conventional hard disks.[91]

Other storage products included Sun Fire X4500 storage server and SAM-QFS filesystem and storage management software.

HPC solutions

Sun marketed the Sun Constellation System for High-Performance Computing (HPC). Even before the introduction of the Sun Constellation System in 2007, Sun's products were in use in many of the TOP500 systems and supercomputing centers:
The Sun HPC ClusterTools product was a set of Message Passing Interface (MPI) libraries and tools for running parallel jobs on Solaris HPC clusters. Beginning with version 7.0, Sun switched from its own implementation of MPI to Open MPI, and donated engineering resources to the Open MPI project.

Sun was a participant in the OpenMP language committee. Sun Studio compilers and tools implemented the OpenMP specification for shared memory parallelization.

In 2006, Sun built the TSUBAME supercomputer, which was until June 2008 the fastest supercomputer in Asia. Sun built Ranger at the Texas Advanced Computing Center (TACC) in 2007. Ranger had a peak performance of over 500 TFLOPS, and was the 6th most powerful supercomputer on the TOP500 list in November 2008. Sun announced an OpenSolaris distribution that integrated many of Sun's HPC products and other 3rd-party solutions.[93]

Staff

Notable Sun employees included John Gilmore, Josh Weiss, Whitfield Diffie, Radia Perlman, Marc Tremblay, and Charitha Jayasuriya. Sun was an early advocate of Unix-based networked computing, promoting TCP/IP and especially NFS, as reflected in the company's motto "The Network Is The Computer", coined by John Gage. James Gosling led the team which developed the Java programming language. Jon Bosak led the creation of the XML specification at W3C.

Sun staff published articles on the company's blog site.[94] Staff were encouraged to use the site to blog on any aspect of their work or personal life, with few restrictions placed on staff, other than commercially confidential material. Jonathan I. Schwartz was one of the first CEOs of large companies to regularly blog; his postings were frequently quoted and analyzed in the press.[95][96] In 2005, Sun Microsystems was one of the first Fortune 500 companies that instituted a formal Social Media program.

Acquisition by Oracle

Sun was sold to Oracle Corporation in 2009.[66] Sun's staff were asked to share anecdotes about their experiences at Sun. A web site containing videos, stories, and photographs from 27 years at Sun was made available on September 2, 2009.[97] In October, Sun announced a second round of thousands of employees to be laid off, blamed partially on delays in approval of the merger.[98] The transaction completed in early 2010.[4] In January 2011 Oracle agreed to pay $46 million to settle charges that it submitted false claims to US federal government agencies and paid "kickbacks" to systems integrators.[99] In February 2011 Sun's former Menlo Park, California campus of about 1,000,000 square feet (93,000 m2) was sold, and it was announced that it would become headquarters for Facebook.[100][101] The sprawling facility built around an enclosed courtyard had been nicknamed "Sun Quentin".[102] On September 1, 2011, Sun India legally became part of Oracle. It had been delayed due to legal issues in Indian court.[citation needed]

Environmentalism


From Wikipedia, the free encyclopedia

Environmentalism is a broad philosophy, ideology and social movement regarding concerns for environmental protection and improvement of the health of the environment, particularly as the measure for this health seeks to incorporate the concerns of non-human elements. Environmentalism advocates the preservation, restoration and/or improvement of the natural environment, and may be referred to as a movement to control pollution or protect plant and animal diversity.[1] For this reason, concepts such as a land ethic, environmental ethics, biodiversity, ecology and the biophilia hypothesis figure predominantly.

At its crux, environmentalism is an attempt to balance relations between humans and the various natural systems on which they depend in such a way that all the components are accorded a proper degree of sustainability. The exact measures and outcomes of this balance is controversial and there are many different ways for environmental concerns to be expressed in practice. Environmentalism and environmental concerns are often represented by the color green,[2] but this association has been appropriated by the marketing industries and is a key tactic of greenwashing. Environmentalism is opposed by anti-environmentalism, which says that the Earth is less fragile than some environmentalists maintain, and portrays environmentalism as overreacting to the human contribution to climate change or opposing human advancement.[3]

Definitions

Environmentalism denotes a social movement that seeks to influence the political process by lobbying, activism, and education in order to protect natural resources and ecosystems. The word was first coined in 1922.[citation needed]

An environmentalist is a person who may speak out about our natural environment and the sustainable management of its resources through changes in public policy or individual behavior. This may include supporting practices such as informed consumption, conservation initiatives, investment in renewable resources, improved efficiencies in the materials economy, transitioning to new accounting paradigms such as Ecological economics and renewing and revitalizing our connections with non-human life.

In various ways (for example, grassroots activism and protests), environmentalists and environmental organizations seek to give the natural world a stronger voice in human affairs.[4]

In general terms, environmentalists advocate the sustainable management of resources, and the protection (and restoration, when necessary) of the natural environment through changes in public policy and individual behavior. In its recognition of humanity as a participant in ecosystems, the movement is centered around ecology, health, and human rights.

While the term Environmentalism focuses more on the environmental and nature-related aspects of Green ideology and politics, Ecologism as a term combines the ideology of Social ecology and Environmentalism. Ecologism as a term is more commonly used in most continental European languages while Environmentalism is more commonly used in English language but they have a slightly different connotation.

History

A concern for environmental protection has recurred in diverse forms, in different parts of the world, throughout history. For example, in Europe, King Edward I of England banned the burning of sea-coal by proclamation in London in 1272, after its smoke had become a problem.[5][6] The fuel was so common in England that this earliest of names for it was acquired because it could be carted away from some shores by the wheelbarrow.

Early environmental legislation


Levels of air pollution rose during the Industrial Revolution, sparking the first modern environmental laws to be passed in the mid-19th century.

The origins of the environmental movement lay in the response to increasing levels of smoke pollution in the atmosphere during the Industrial Revolution. The emergence of great factories and the concomitant immense growth in coal consumption gave rise to an unprecedented level of air pollution in industrial centers; after 1900 the large volume of industrial chemical discharges added to the growing load of untreated human waste.[7] The first large-scale, modern environmental laws came in the form of Britain's Alkali Acts, passed in 1863, to regulate the deleterious air pollution (gaseous hydrochloric acid) given off by the Leblanc process, used to produce soda ash. An Alkali inspector and four sub-inspectors were appointed to curb this pollution. The responsibilities of the inspectorate were gradually expanded, culminating in the Alkali Order 1958 which placed all major heavy industries that emitted smoke, grit, dust and fumes under supervision.

The late 19th century also saw the passage of the first wildlife conservation laws. The zoologist Alfred Newton published a series of investigations into the Desirability of establishing a 'Close-time' for the preservation of indigenous animals between 1872 and 1903. His advocacy for legislation to protect animals from hunting during the mating season led to the formation of the Royal Society for the Protection of Birds and influenced the passage of the Sea Birds Preservation Act in 1869 as the first nature protection law in the world.[8][9]

For most of the century from 1850 to 1950, however, the primary environmental cause was the mitigation of air pollution. The Coal Smoke Abatement Society was formed in 1898 making it one of the oldest environmental NGOs. It was founded by artist Sir William Blake Richmond, frustrated with the pall cast by coal smoke. Although there were earlier pieces of legislation, the Public Health Act 1875 required all furnaces and fireplaces to consume their own smoke. It also provided for sanctions against factories that emitted large amounts of black smoke. The provisions of this law were extended in 1926 with the Smoke Abatement Act to include other emissions, such as soot, ash and gritty particles and to empower local authorities to impose their own regulations.

It was, however, only under the impetus of the Great Smog of 1952 in London, which almost brought the city to a standstill and may have caused upward of 6,000 deaths that the Clean Air Act 1956 was passed and pollution in the city was finally brought to an end. Financial incentives were offered to householders to replace open coal fires with alternatives (such as installing gas fires), or for those who preferred, to burn coke instead (a byproduct of town gas production) which produces minimal smoke. 'Smoke control areas' were introduced in some towns and cities in which only smokeless fuels could be burnt and power stations were relocated away from cities. The act formed an important impetus to modern environmentalism, and caused a rethinking of the dangers of environmental degradation to people's quality of life.[10]

First environmental movements

Early interest in the environment was a feature of the Romantic movement in the early 19th century. The poet William Wordsworth travelled extensively in the Lake District and wrote that it is a "sort of national property in which every man has a right and interest who has an eye to perceive and a heart to enjoy".[11]

John Ruskin an influential thinker who articulated the Romantic ideal of environmental protection and conservation.

Systematic efforts on behalf of the environment only began in the late 19th century; it grew out of the amenity movement in Britain in the 1870s, which was a reaction to industrialization, the growth of cities, and worsening air and water pollution. Starting with the formation of the Commons Preservation Society in 1865, the movement championed rural preservation against the encroachments of industrialisation. Robert Hunter, solicitor for the society, worked with Hardwicke Rawnsley, Octavia Hill, and John Ruskin to lead a successful campaign to prevent the construction of railways to carry slate from the quarries, which would have ruined the unspoilt valleys of Newlands and Ennerdale. This success led to the formation of the Lake District Defence Society (later to become The Friends of the Lake District).[12]

In 1893 Hill, Hunter and Rawnsley agreed to set up a national body to coordinate environmental conservation efforts across the country; the "National Trust for Places of Historic Interest or Natural Beauty" was formally inaugurated in 1894.[13] The organisation obtained secure footing through the 1907 National Trust Bill, which gave the trust the status of a statutory corporation.[14] and the bill was passed in August 1907.[15]

An early "Back-to-Nature" movement, which anticipated the romantic ideal of modern environmentalism, was advocated by intellectuals such as John Ruskin, William Morris, George Bernard Shaw and Edward Carpenter, who were all against consumerism, pollution and other activities that were harmful to the natural world.[16] The movement was a reaction to the urban conditions of the industrial towns, where sanitation was awful, pollution levels intolerable and housing terribly cramped. Idealists championed the rural life as a mythical Utopia and advocated a return to it. John Ruskin argued that people should return to a small piece of English ground, beautiful, peaceful, and fruitful. We will have no steam engines upon it . . . we will have plenty of flowers and vegetables . . . we will have some music and poetry; the children will learn to dance to it and sing it.[17]

Practical ventures in the establishment of small cooperative farms were even attempted and old rural traditions, without the "taint of manufacture or the canker of artificiality", were enthusiastically revived, including the Morris dance and the maypole.[18]

These ideas also inspired various environmental groups in the UK, such as the Royal Society for the Protection of Birds, established in 1889 by Emily Williamson as a protest group to campaign for greater protection for the indigenous birds of the island.[19][20] The Society attracted growing support from the suburban middle-classes as well as support from many other influential figures, such as the ornithologist Professor Alfred Newton. By 1900, public support for the organisation had grown, and it had over 25,000 members. The Garden city movement incorporated many environmental concerns into its urban planning manifesto; the Socialist League and The Clarion movement also began to advocate measures of nature conservation.[21]

Original title page of Walden by Henry David Thoreau.

The movement in the United States began in the late 19th century, out of concerns for protecting the natural resources of the West, with individuals such as John Muir and Henry David Thoreau making key philosophical contributions. Thoreau was interested in peoples' relationship with nature and studied this by living close to nature in a simple life. He published his experiences in the book Walden, which argues that people should become intimately close with nature. Muir came to believe in nature's inherent right, especially after spending time hiking in Yosemite Valley and studying both the ecology and geology. He successfully lobbied congress to form Yosemite National Park and went on to set up the Sierra Club in 1892. The conservationist principles as well as the belief in an inherent right of nature were to become the bedrock of modern environmentalism.

In the 20th century, environmental ideas continued to grow in popularity and recognition. Efforts were starting to be made to save some wildlife, particularly the American Bison. The death of the last Passenger Pigeon as well as the endangerment of the American Bison helped to focus the minds of conservationists and popularize their concerns. In 1916 the National Park Service was founded by US President Woodrow Wilson.

The Forestry Commission was set up in 1919 in Britain to increase the amount of woodland in Britain by buying land for afforestation and reforestation. The commission was also tasked with promoting forestry and the production of timber for trade.[22] During the 1920s the Commission focused on acquiring land to begin planting out new forests; much of the land was previously used for agricultural purposes. By 1939 the Forestry Commission was the largest landowner in Britain.[23]

During the 1930s the Nazis had elements that were supportive of animal rights, zoos and wildlife,[24] and took several measures to ensure their protection.[25] In 1933 the government created a stringent animal-protection law and in 1934, Das Reichsjagdgesetz (The Reich Hunting Law) was enacted which limited hunting.[26][27] Several Nazis were environmentalists (notably Rudolf Hess), and species protection and animal welfare were significant issues in the regime.[25] In 1935, the regime enacted the "Reich Nature Protection Act" (Reichsnaturschutzgesetz). The concept of the Dauerwald (best translated as the "perpetual forest") which included concepts such as forest management and protection was promoted and efforts were also made to curb air pollution.[28]

In 1949, A Sand County Almanac by Aldo Leopold was published. It explained Leopold’s belief that humankind should have moral respect for the environment and that it is unethical to harm it. The book is sometimes called the most influential book on conservation.

Throughout the 1950s, 1960s, 1970s and beyond, photography was used to enhance public awareness of the need for protecting land and recruiting members to environmental organizations. David Brower, Ansel Adams and Nancy Newhall created the Sierra Club Exhibit Format Series, which helped raise public environmental awareness and brought a rapidly increasing flood of new members to the Sierra Club and to the environmental movement in general. "This Is Dinosaur" edited by Wallace Stegner with photographs by Martin Litton and Philip Hyde prevented the building of dams within Dinosaur National Monument by becoming part of a new kind of activism called environmentalism that combined the conservationist ideals of Thoreau, Leopold and Muir with hard-hitting advertising, lobbying, book distribution, letter writing campaigns, and more. The powerful use of photography in addition to the written word for conservation dated back to the creation of Yosemite National Park, when photographs persuaded Abraham Lincoln to preserve the beautiful glacier carved landscape for all time. The Sierra Club Exhibit Format Series galvanized public opposition to building dams in the Grand Canyon and protected many other national treasures. The Sierra Club often led a coalition of many environmental groups including the Wilderness Society and many others. After a focus on preserving wilderness in the 1950s and 1960s, the Sierra Club and other groups broadened their focus to include such issues as air and water pollution, population concern, and curbing the exploitation of natural resources.

Post-war expansion


Silent Spring by Rachael Carson, published in 1962, included an endorsement by William O. Douglas.[29]

In 1962, Silent Spring by American biologist Rachel Carson was published. The book cataloged the environmental impacts of the indiscriminate spraying of DDT in the US and questioned the logic of releasing large amounts of chemicals into the environment without fully understanding their effects on ecology or human health. The book suggested that DDT and other pesticides may cause cancer and that their agricultural use was a threat to wildlife, particularly birds.[30] The resulting public concern led to the creation of the United States Environmental Protection Agency in 1970 which subsequently banned the agricultural use of DDT in the US in 1972. The limited use of DDT in disease vector control continues to this day in certain parts of the world and remains controversial. The book's legacy was to produce a far greater awareness of environmental issues and interest into how people affect the environment. With this new interest in environment came interest in problems such as air pollution and petroleum spills, and environmental interest grew. New pressure groups formed, notably Greenpeace and Friends of the Earth, as well as notable local organizations such as the Wyoming Outdoor Council, which was founded in 1967.

In the 1970s, the environmental movement gained rapid speed around the world as a productive outgrowth of the counterculture movement.[31]

The world's first political parties to campaign on a predominantly environmental platform were the United Tasmania Group Tasmania, Australia and the Values Party of New Zealand.[32][33] The first green party in Europe was the Popular Movement for the Environment, founded in 1972 in the Swiss canton of Neuchâtel. The first national green party in Europe was PEOPLE, founded in Britain in February 1973, which eventually turned into the Ecology Party, and then the Green Party.

Protection of the environment also became important in the developing world; the Chipko movement was formed in India under the influence of Mohandas Gandhi and they set up peaceful resistance to deforestation by literally hugging trees (leading to the term "tree huggers"). Their peaceful methods of protest and slogan "ecology is permanent economy" were very influential.

Another milestone in the movement was the creation of an Earth Day. Earth Day was first observed in San Francisco and other cities on March 21, 1970, the first day of Spring. It was created to give awareness to environmental issues. On March 21, 1971, United Nations Secretary-General U Thant spoke of a spaceship Earth on Earth Day, hereby referring to the ecosystem services the earth supplies to us, and hence our obligation to protect it (and with it, ourselves). Earth Day is now coordinated globally by the Earth Day Network,[34] and is celebrated in more than 175 countries every year.[35]

The UN's first major conference on international environmental issues, the United Nations Conference on the Human Environment (also known as the Stockholm Conference), was held on June 5–16, 1972. It marked a turning point in the development of international environmental politics.[36]

By the mid-1970s, many felt that people were on the edge of environmental catastrophe. The Back-to-the-land movement started to form and ideas of environmental ethics joined with anti-Vietnam War sentiments and other political issues. These individuals lived outside normal society and started to take on some of the more radical environmental theories such as deep ecology. Around this time more mainstream environmentalism was starting to show force with the signing of the Endangered Species Act in 1973 and the formation of CITES in 1975. Significant amendments were also enacted to the United States Clean Air Act[37] and Clean Water Act.[38]

In 1979, James Lovelock, a British scientist, published Gaia: A new look at life on Earth, which put forth the Gaia Hypothesis; it proposes that life on Earth can be understood as a single organism. This became an important part of the Deep Green ideology. Throughout the rest of the history of environmentalism there has been debate and argument between more radical followers of this Deep Green ideology and more mainstream environmentalists.

During the 1980s the growing awareness of global warming and other climate change issues brought environmentalism into greater public debate. In 1986 the international conservation organisation the World Wildlife Fund renamed itself the Worldwide Fund For Nature to reflect a shift to a more strategic approach. Still known as WWF, however, the organisation brought together religious authorities representing the five major world religions (Buddhism, Christianity, Hinduism, Islam, and Judaism) to prepare the 1986 Assisi Declarations. These theological statements, published by the WWF and UNEP, identified the responsibilities towards the care of nature expected of followers of each religion thus providing spiritual motivation for environmental action. The full texts, with additional similar declarations from Bahá’ísm, Jainism, Shintoism, Sikhism and Zoroastrianism were later included in the 2003 World Bank publication 'Faith In Conservation'.[39]

Today

Environmentalism has changed to deal with new issues such as global warming, overpopulation and genetic engineering. Many youth of today's society are more aware of the state of the planet because they grew up with Earth Day in place. School Eco Clubs are now working to create new ideals for the future through sustainable schools and other minor changes in student lives like buying organic food, clothing and personal care items. In the future, many of the jobs opening up will have environmentalist aspects.

Recent research demonstrates that a precipitous decline in the public's interest in 19 different areas of environmental concern.[40] Americans are less likely be actively participating in an environmental movement or organization and more likely to identify as “unsympathetic” an environmental movement then in 2000.[41] This is likely a lingering factor of the Great Recession in 2008. Since 2005 the percentage of Americans agreeing that the environment should be given priority over economic growth has dropped 10 points, in contrast, those feeling that growth should be given priority “even if the environment suffers to some extent” has risen 12 percent.[41] These numbers point to the growing complexity of environmentalism because it is tied into economics.

Environmental movement

Before flue-gas desulfurization was installed, the air-polluting emissions from this power plant in New Mexico contained excessive amounts of sulfur dioxide.

The environmental movement (a term that sometimes includes the conservation and green movements) is a diverse scientific, social, and political movement. Though the movement is represented by a range of organizations, because of the inclusion of environmentalism in the classroom curriculum,[42][43] the environmental movement has a younger demographic than is common in other social movements (see green seniors).

Environmentalism as a movement covers broad areas of institutional oppression, including for example: consumption of ecosystems and natural resources into waste, dumping waste into disadvantaged communities, air pollution, water pollution, weak infrastructure, exposure of organic life to toxins, mono-culture, anti-polythene drive (jhola movement) and various other focuses. Because of these divisions, the environmental movement can be categorized into these primary focuses: environmental science, environmental activism, environmental advocacy, and environmental justice.[44]

Free market environmentalism

Free market environmentalism is a theory that argues that the free market, property rights, and tort law provide the best tools to preserve the health and sustainability of the environment. It considers environmental stewardship to be natural, as well as the expulsion of polluters and other aggressors through individual and class action. It has been supported by libertarians and many conservatives.[45]

Evangelical environmentalism

Evangelical environmentalism is an environmental movement in the United States in which some Evangelicals have emphasized biblical mandates concerning humanity's role as steward and subsequent responsibility for the caretaking of Creation. While the movement has focused on different environmental issues, it is best known for its focus of addressing climate action from a biblically grounded theological perspective. The Evangelical Climate Initiative argues that human-induced climate change will have severe consequences and impact the poor the hardest, and that God's mandate to Adam to care for the Garden of Eden also applies to evangelicals today, and that it is therefore a moral obligation to work to mitigate climate impacts and support communities in adapting to change.[46]

Preservation and conservation

Environmental preservation in the United States and other parts of the world, including Australia, is viewed as the setting aside of natural resources to prevent damage caused by contact with humans or by certain human activities, such as logging, mining, hunting, and fishing, often to replace them with new human activities such as tourism and recreation.[47] Regulations and laws may be enacted for the preservation of natural resources.

Organizations and conferences

Environmental organizations can be global, regional, national or local; they can be government-run or private (NGO). Environmentalist activity exists in almost every country. Moreover, groups dedicated to community development and social justice also focus on environmental concerns.

There are some volunteer organizations. For example Ecoworld and Paryawaran Sachetak Samiti which is about the environment and is based in team work and volunteer work. Some US environmental organizations, among them the Natural Resources Defense Council and the Environmental Defense Fund, specialize in bringing lawsuits (a tactic seen as particularly useful in that country). Other groups, such as the US-based National Wildlife Federation, the Nature Conservancy, and The Wilderness Society, and global groups like the World Wide Fund for Nature and Friends of the Earth, disseminate information, participate in public hearings, lobby, stage demonstrations, and may purchase land for preservation. Statewide nonprofit organizations such as the Wyoming Outdoor Council often collaborate with these national organizations and employ similar strategies. Smaller groups, including Wildlife Conservation International, conduct research on endangered species and ecosystems. More radical organizations, such as Greenpeace, Earth First!, and the Earth Liberation Front, have more directly opposed actions they regard as environmentally harmful. While Greenpeace is devoted to nonviolent confrontation as a means of bearing witness to environmental wrongs and bringing issues into the public realm for debate, the underground Earth Liberation Front engages in the clandestine destruction of property, the release of caged or penned animals, and other criminal acts. Such tactics are regarded as unusual within the movement, however.

On an international level, concern for the environment was the subject of a United Nations Conference on the Human Environment in Stockholm in 1972, attended by 114 nations. Out of this meeting developed UNEP (United Nations Environment Programme) and the follow-up United Nations Conference on Environment and Development in 1992. Other international organizations in support of environmental policies development include the Commission for Environmental Cooperation (as part of NAFTA), the European Environment Agency (EEA), and the Intergovernmental Panel on Climate Change (IPCC).

Usage in popular culture

The popular media have been used to convey conservation messages in the U.S. For instance, the U.S. Forest Service created Smokey the Bear in 1944; he appeared in countless posters, radio and television programs, movies, press releases, and other guises to warn about forest fires.[48] The comic strip Mark Trail, by environmentalist Ed Dodd, began in 1946; it still appears weekly in 175 newspapers. Another example is the children's animated show Captain Planet and the Planeteers, created by Ted Turner and Barbara Pyle in 1989 to inform kids on environmental issues. The show aired for six seasons and 113 episodes, in 100 countries worldwide from 1990 to 1996.[49]

An alternative view

Many environmentalists believe that human interference with 'nature' should be restricted or minimised as a matter of urgency (for the sake of life, or the planet, or just for the benefit of the human species),[50] whereas environmental skeptics and anti-environmentalists do not believe that there is such a need.[51][citation needed] One can also regard oneself as an environmentalist and believe that human 'interference' with 'nature' should be increased.[52] Nevertheless, there is a risk that the shift from emotional environmentalism into the technical management of natural resources and hazards could decrease the touch of humans with nature, leading to a weaker concern with environment preservation.[53]
