Overconsumption is a situation where resource use has outpaced the sustainable capacity of the ecosystem. A prolonged pattern of overconsumption leads to environmental degradation and the eventual loss of resource bases.
Generally, the discussion of overconsumption parallels that of human overpopulation; that is the more people, the more consumption of raw materials
takes place to sustain their lives. But, humanity's overall impact on
the planet is affected by many factors besides the raw number of people.
Their lifestyle (including overall affluence and resource utilization)
and the pollution they generate (including carbon footprint) are equally important. Currently, the inhabitants of the developed nations
of the world consume resources at a rate almost 32 times greater than
those of the developing world, who make up the majority of the human
population (7.4 billion people).
However, the developing world is a growing market of consumption.
These nations are quickly gaining more purchasing power and it is
expected that the Global South, which includes cities in Asia, Latin
America and Africa, will account for 56% of consumption growth by 2030. This means that consumption rates will plateau for the developed nations and shift more into these developing countries.
The theory of overpopulation reflects issues of carrying capacity
without taking into account per capita consumption, by which developing
nations are evaluated to consume more than their land can support. It
is expected that world population growth will increase by 41% from 2000
to 2050, reaching a height of 8.9 billion people. On top of the rapid
growth expectancy, it will be highly concentrated in the developing
nations. This poses issues with inequality of consumption as well. The
nations that will come into consumer dominance must abstain from abusing
certain forms of consumption, especially energy consumption of CO2. Green parties and the ecology movement often argue that consumption per person, or ecological footprint, is typically lower in poor than in rich nations.
Causes
In
understanding the effects of over-consumption, it is pertinent to
understand what causes the phenomenon. There is a spectrum of goods and
services that the world population constantly consume. These range from
food and beverage, clothing and footwear, housing, energy, technology,
transportation, education, health and personal care, financial services
and other utilities.
Each of these require a different resource and once that resource is
exploited to a certain point, that qualifies as over consumption. Since
the developing nations are rising quickly into the consumer class, it is
important to note the trends happening in these nations. According to
the World Bank, the highest shares of consumption lie in food and
beverage and clothing and footwear. This applies regardless of sector of
income.
Two main factors of why we buy so much and so often is due to planned and perceived obsolescence.
This factor of production was introduced first in the United States and
it revolves around the design of products and with these methods, the
products are intentionally designed to get rid of after a short amount
of time. As of 2012, only 1% of goods purchased were still in use after 6
months. This is due to planned and perceived obsolescence. When it is
planned, designers create products that will not be able to work after a
certain amount of time but they work for enough time to ensure the
customers will come back to buy again. Perceived obsolescence comes in a
lot with fashion and trends and fueled by advertising and media
consumption. Through this technique, consumers are convinced that
certain products do not have value anymore because it is out of style,
and in order to have value, consumers must buy more up to date styles.
Here is where fast fashion was born.
As of 2015, the top five consumer markets in the world included the
United States, Japan, Germany, China and France.
Effects
A fundamental effect of overconsumption is a reduction in the planet's carrying capacity. Excessive unsustainable consumption will exceed the long term carrying capacity of its environment (ecological overshoot) and subsequent resource depletion, environmental degradation and reduced ecosystem health.
Looking at the two largest sectors of over consumption, the
fashion and food industries, we can see most of the harmful effects on
the Earth starting here. The fashion industry has created a new venue,
fast fashion, which in 2013 produced 15.1 million tons of textile waste
and of that, 12.8 million tons were thrown out. The United States,
being the largest consumer market, deals with excess clothing by
exporting it to poorer, developing nations but this solution is not
sustainable because the demand will go down as cheap clothing becomes
more readily available. Another way of disposal is to throw out into
landfills or burn up in incinerators which is the least sustainable
disposal solution.
The food industry is the other largest sector of consumption and
studies show that people waste a fifth of food products just through
disposal or overconsumption. The UN Food and Agriculture Organization
collected data and found that by the time food reaches the consumer, 9%
(160 million tons) goes uneaten and 10% is lost to overconsumption -
meaning consumers ate more than the calorie intake requirement. Other
aspects of losses surrounding dry matter came at each stage in the food
system, the highest amount being from livestock production at 43.9%,
transportation accounted for 18% and consumer waste accounting for 12.2%
loss. When the consumer takes in too much, this not only explains
losses in the beginning of the stage at production (and over production)
but also lends itself to overconsumption of energy and protein, having
harmful effects on the body.
The scale of modern life's overconsumption has enabled an overclass to exist, displaying affluenza and obesity. However once again both of these claims are controversial with the latter being correlated to other factors more so than over-consumption. Within the topic of overconsumption there are many other ideas that should be considered in order to find the true cause of it. Some important events that coincide are poverty, population and the development of an area. Overconsumption can also lead to a decline in the economy and financial instability.
In the long term, these effects can lead to increased conflict over dwindling resources and in the worst case a Malthusian catastrophe. Lester Brown of the Earth Policy Institute,
has said: "It would take 1.5 Earths to sustain our present level of
consumption. Environmentally, the world is in an overshoot mode."
As of 2012, the United States alone was using 30% of the world’s
resources and if everyone were to consume at that rate, we would need
3-5 planets to sustain this type of living. Resources are quickly
becoming depleted, with about ⅓ already gone. With new consumer markets
rising in the developing countries which account for a much higher
percent of the world’s population, this number can only rise.
Economic growth
The Worldwatch Institute
said China and India, with their booming economies, along with the
United States, are the three planetary forces that are shaping the
global biosphere. The State of the World 2005 report said the two countries' high economic growth exposed the reality of severe pollution. The report states that
The world's ecological capacity is simply insufficient to satisfy the ambitions of China, India, Japan, Europe and the United States as well as the aspirations of the rest of the world in a sustainable way.
Footprint
The idea of overconsumption is also strongly tied to the idea of an
ecological footprint. The term “ecological footprint” refers to the
“resource accounting framework for measuring human demand on the
biosphere.” Currently, China is roughly 11 times lower in per capita
footprint, yet has a population that is more than four times the size of
the USA. It is estimated that if China developed to the level of the
United States that world consumption rates would roughly double. According to Scientific American, one person from China uses 53 times fewer resources than the average American.
A 2018 study published in Science postulates that meat consumption is set to increase as the result of human population growth and rising affluence, which will increase greenhouse gas emissions and further reduce biodiversity.
Counteractions
The most obvious solution to the issue of overconsumption is to simply slow the rate at which materials are becoming depleted.
Less consumption naturally has negative effects on economies - so
instead, countries must look to curb consumption rates while allowing
for new industries, such as renewable energy and recycling
technologies, to flourish and deflect some of the economic burden. A
fundamental shift in the global economy may be necessary in order to
account for the current change that is taking place or that will need to
take place. Movements and lifestyle choices related to stopping
overconsumption include: anti-consumerism, freeganism, green economics, ecological economics, degrowth, frugality, downshifting, simple living, minimalism, and thrifting.
Recent grassroots movements have been coming up with creative ways to decrease the amount of goods we consume. The Freecycle Network
is a network of people in one's community that are willing to trade
goods for other goods or services. It is a new take on thrifting while
still being beneficial to both parties.
Other researchers and movements such as the Zeitgeist Movement suggest a new socioeconomic model which, through a structural increase of efficiency, collaboration and locality in production as well as effective sharing, increased modularity, sustainability and optimal design of products, are expected to reduce resource-consumption.
