Environmental philosophy is a branch of philosophy that is concerned with the natural environment and humans' place within it. It asks crucial questions about human environmental relations such as "What do we mean when we talk about nature?" "What is the value of the natural, that is non-human environment to us, or in itself?" "How should we respond to environmental challenges such as environmental degradation, pollution and climate change?" "How can we best understand the relationship between the natural world and human technology and development?" and "What is our place in the natural world?" Environmental philosophy includes environmental ethics, environmental aesthetics, ecofeminism, environmental hermeneutics, and environmental theology. Some of the main areas of interest for environmental philosophers are:
- Defining environment and nature
- How to value the environment
- Moral status of animals and plants
- Endangered species
- Environmentalism and deep ecology
- Aesthetic value of nature
- Intrinsic value
- Wilderness
- Restoration of nature
- Consideration of future generations
- Ecophenomenology
Contemporary issues
Modern issues within environmental philosophy include but are not restricted to the concerns of environmental activism, questions raised by science and technology, environmental justice, and climate change. These include issues related to the depletion of finite resources and other harmful and permanent effects brought on to the environment by humans, as well as the ethical and practical problems raised by philosophies and practices of environmental conservation, restoration, and policy in general. Another question that has settled on the minds of modern environmental philosophers is "Do rivers have rights?" At the same time environmental philosophy deals with the value human beings attach to different kinds of environmental experience, particularly how experiences in or close to non-human environments contrast with urban or industrialized experiences, and how this varies across cultures with close attention paid to indigenous people.
Modern history
Environmental philosophy emerged as a branch of philosophy in 1970s. Early environmental philosophers include Richard Routley, Arne Næss, and J. Baird Callicott. The movement was an attempt to connect with humanity's sense of alienation from nature in a continuing fashion throughout history. This was very closely related to the development at the same time of ecofeminism, an intersecting discipline. Since then its areas of concern have expanded significantly.
The field is today characterized by a notable diversity of stylistic, philosophical and cultural approaches to human environmental relationships, from personal and poetic reflections on environmental experience and arguments for panpsychism to Malthusian applications of game theory or the question of how to put an economic value on nature's services. A major debate arose in the 1970s and 80s was that of whether nature has intrinsic value in itself independent of human values or whether its value is merely instrumental, with ecocentric or deep ecology approaches emerging on the one hand versus consequentialist or pragmatist anthropocentric approaches on the other.
Another debate that arose at this time was the debate over whether there really is such a thing as wilderness or not, or whether it is merely a cultural construct with colonialist implications as suggested by William Cronon. Since then, readings of environmental history and discourse have become more critical and refined. In this ongoing debate, a diversity of dissenting voices have emerged from different cultures around the world questioning the dominance of Western assumptions, helping to transform the field into a global area of thought.
In recent decades, there has been a significant challenge to deep ecology and the concepts of nature that underlie it, some arguing that there is not really such a thing as nature at all beyond some self-contradictory and even politically dubious constructions of an ideal other that ignore the real human-environmental interactions that shape our world and lives. This has been alternately dubbed the postmodern, constructivist, and most recently post-naturalistic turn in environmental philosophy. Environmental aesthetics, design and restoration have emerged as important intersecting disciplines that keep shifting the boundaries of environmental thought, as have the science of climate change and biodiversity and the ethical, political and epistemological questions they raise.
Deep ecology movement
In 1984, George Sessions and Arne Næss articulated the principles of the new Deep Ecology Movement. These basic principles are:
- The well-being and flourishing of human and non-human life have value.
- Richness and diversity of life forms contribute to the realization of these values and are also values in themselves.
- Humans have no right to reduce this richness and diversity except to satisfy vital needs.
- The flourishing of human life and cultures is compatible with a substantial decrease in the human population.
- Present human interference with the nonhuman world is excessive, and the situation is rapidly worsening.
- Policies must therefore be changed. These policies affect basic economic, technological, and ideological structures. The resulting state of affairs will be deeply different from the present.
- The ideological change is mainly that of appreciating life quality (dwelling in situations of inherent value), rather than adhering to an increasingly higher standard of living. There will be a profound awareness of the difference between big and great.
- Those who subscribe to the foregoing points have an obligation directly or indirectly to try to implement the necessary changes.
