Over-consumption

Over-consumption is a concept akin to overpopulation, referring to situations where per capita consumption is so high that even in spite of a moderate population density, sustainability? is not achieved. For example, the People's Republic of China has an area comparable to that of the United States of America. China's population density is 4.7 times higher than that of the USA, but it's per capita energy consumption is 9 times lower than that of the USA, so that in spite of it's larger population, China uses only half the amount of energy consumed by the USA.

The concept was coined to counter rhetorical use of overpopulation, simplistically referring to population density without taking into account per capita consumption, by which developing nations are judged as consuming more than their economy can support. A key argument, often made by Green parties and the ecology movement, is that consumption per person, or ecological footprint? , is lower in poor than in rich nations.

Causes

Over-consumption is measurable. Two articles in Physics Today, July 2004, showed that the combination of over-consumption of energy and overpopulation may have serious consequences for the future of mankind if action is not taken in this generation. An excessive consumption of energy, that is generated from the combustion of fossil fuels, is the main cause of global warming, and other pollution.

Factors contributing to over-consumption include over-illumination, overuse of credit facilities which encourage immediate conspicuous consumption and the concept that the present ethos? is that of a throw-away society.

Root causes

Over-consumption can be rooted in an unbalanced worldview where the needs of other people and species are devalued in favor of self-centered desires. Such behavior is often prevalent in materialistic and technologically advanced cultures that have grown out of a mechanistic philosophy characterized by a man/nature or subject/object dichotomy.

Effects

Over-consumption creates an overclass who may suffer from affluenza? and obesity. Excessive unsustainable consumption leads to resource depletion, environmental degradation and reduced ecological health? . In the longterm these effects can lead to increased conflict over dwindling resources and in the worst case a Malthusian catastrophe? .

The scale of modern life's over-consumption has enabled an overclass to exist, displaying affluenza? and obesity.

Economic Growth

However, the Worldwatch Institute said the booming economies of China and India are planetary powers that are shaping the global biosphere. The State of the World 2006 report said the two countries' high economic growth hid a reality of severe pollution. The report states:

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.

It said that if China and India were to consume as much resources per capita as Japan in 2030 together they would require a full planet Earth to meet their needs.

Population Growth

Americans constitute less than 5% of the world's population? , but produce 25% of the world’s CO2,[2] consume 25% of world’s resources? ,[3] including 26% of the world's energy,[4] although having only 3% of the world’s known oil reserves,[5] and generate roughly 30% of world’s waste.[6] [7] An Americans' impact on the environment? is at least 250 times greater than a Sub-Saharan African's.[8] [9]

U.S. Census Bureau figures show the U.S. population grew by 2.8 million between July 1, 2004, and July 1, 2005. If current birth rate and immigration rates were to remain unchanged for another 60 to 70 years, US population would double to some 600 million people.[10]

If China and India were to consume as much per capita as United States or Japan, in 2030 together they would require a full planet Earth to meet their needs.[11]

Counteractions

Movements and ideologies have formed in recent decades to reduce over-consumption. These include anti-consumerism? , ecological economics? , freeganism and green economics? .
