Question

Quizplus · Accepted Answer

All of the listed human factors can contribute to the current mass extinction. Overpopulation leads to increased demand for resources and land, leading to habitat loss and fragmentation. Pollution can directly harm animals and the environment, leading to decreased reproductive success and increased mortality rates. Man-made contributions to global climate change can alter weather patterns, leading to droughts or floods that disrupt ecosystems. Encroachment on animal habitat can lead to the destruction of ecosystems and displacement or extinction of species. All of these factors are interconnected and exacerbate each other, leading to a greater impact on biodiversity.
