Ecological overshoot expressed in terms of how many Earths equivalent of natural resources are consumed by humanity each year. Ecological overshoot is the phenomenon which occurs when the demands made on a natural ecosystem exceed its regenerative capacity. Global ecological overshoot occurs when the demands made by humanity exceed what the ...
Overexploitation, also called overharvesting or ecological overshoot, ... A major theme running through the essay is the growth of human populations, ...
For people, "overshoot" is that portion of their demand or ecological footprint which must be eliminated to be sustainable, or the delta between a sustainable population and what we currently have. [1] [2] Excessive demand leading to overshoot is driven by both consumption and population. [3] Population decline due to overshoot is known as ...
By Aug. 1, 2018, the Global Footprint Network anticipates humanity will have exhausted more of Earth's resources than it can regenerate within one year.
Human ecological overshoot—using resources faster than they can be replenished—has led to environmental degradation, climate change, and biodiversity loss, which in turn threaten the stability and continuity of human societies.
We are operating in overshoot. [68] The concept of ‘ecological overshoot’ can be seen as equivalent to exceeding human carrying capacity. [69] [64] According to the most recent calculations from Global Footprint Network, most of the world's residents live in countries in ecological overshoot (see the map on the right).
These were the references William R. Catton used in a 2008 "retrospective" [8] portraying his paradigm shift into environmental sociology. William Catton came of age in sociology when the major debates were about social-only theoretical orientations (structural-functionalism or consensus theory versus Marxism or conflict theory), and methodology (quantitative versus qualitative).

The latest ecological footprint data shows the world's footprint increased from about 50% undershoot in 1961 to 50% overshoot in 2007, the last year data is available. [3] In 1972 the first edition of The Limits to Growth analyzed the environmental sustainability problem using a system dynamics model. The widely influential book predicted that: [4]
