Almost all of Europe's original forests have been destroyed. Scientists assert that human activity has pushed the earth into a sixth mass extinction event. [5] [6] The loss of biodiversity has been attributed in particular to human overpopulation, continued human population growth and overconsumption of natural resources by the world's wealthy.
Deforestation is defined as the conversion of forest to other land uses (regardless of whether it is human-induced). [ 14 ] Deforestation and forest area net change are not the same: the latter is the sum of all forest losses (deforestation) and all forest gains (forest expansion) in a given period.
According to a 2021 study published in Frontiers in Forests and Global Change, roughly 3% of the planet's terrestrial surface is ecologically and faunally intact, meaning areas with healthy populations of native animal species and little to no human footprint. Many of these intact ecosystems were in areas inhabited by indigenous peoples.
When natural habitats are destroyed or natural resources are depleted, the environment is degraded; direct environmental degradation, such as deforestation, which is readily visible; this can be caused by more indirect process, such as the build up of plastic pollution over time or the buildup of greenhouse gases that causes tipping points in ...
Ecocide (from Greek oikos "home" and Latin cadere "to kill") is the destruction of the environment by humans. [1] Ecocide threatens all human populations who are dependent on natural resources for maintaining ecosystems and ensuring their ability to support future generations.
These hotspots are suffering from habitat loss and destruction. Most of the natural habitat on islands and in areas of high human population density has already been destroyed (WRI, 2003). Islands suffering extreme habitat destruction include New Zealand, Madagascar, the Philippines, and Japan. [7]

When solving problems involving human-environment interactions, whether global or local, one must have a model of human nature that predicts the environmental conditions under which humans will respond well. This model can help design, manage, protect and/or restore environments that enhance reasonable behavior, predict the likely outcomes when ...
