Over-consumption

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 overpopulation; that is the more people, the more consumption of raw materials to sustain their lives. 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).

The theory was coined to augment the discussion of overpopulation, which 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. Green parties and the ecology movement often argue that consumption per person, or ecological footprint, is typically lower in poor than in rich nations.

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 ecological health.
