Global ecological overshoot occurs when the demands made by humanity exceed what the biosphere of Earth can provide through its capacity for renewal. [ 1 ] [ 2 ] Scientific use of the term in the context of the global ecological impact of humanity is attributed to a 1980 book by William R. Catton, Jr. titled Overshoot: The Ecological Basis of ...
Overexploitation does not necessarily lead to the destruction of the resource, nor is it necessarily unsustainable. However, depleting the numbers or amount of the resource can change its quality. For example, footstool palm is a wild palm tree found in Southeast Asia. Its leaves are used for thatching and food wrapping, and overharvesting has ...
In the real world, consumption of fossil fuel resources leads to global warming and climate change. However, little change is being made in many parts of the world. If the peak oil theory proves true, more explorations of viable alternative energy sources, could be more friendly to the environment.
Some scholars believe that the projected peak global population of roughly 9-10 billion people could live sustainably within the earth's ecosystems if humans worked to live sustainably within planetary boundaries. [6] [7] [8] The bulk of environmental impacts are caused by excessive consumption of industrial goods by the world's wealthiest ...
Some were global, but were not as severe—e.g. the 1918 influenza pandemic killed an estimated 3–6% of the world's population. [13] Most global catastrophic risks would not be so intense as to kill the majority of life on earth, but even if one did, the ecosystem and humanity would eventually recover (in contrast to existential risks ).
The structures are considered to be one of the oldest ecosystems on Earth, according to NASA, representing the earliest fossil evidence for life on our planet from at least 3½ billion years ago.
