Detailed explanation-1: -Extinction occurs when species are diminished because of environmental forces such as habitat fragmentation, climate change, natural disaster, overexploitation by humans, and pollution, or because of evolutionary changes in their members (genetic inbreeding, poor reproduction, decline in population numbers).

Detailed explanation-2: -Anthropogenic Extinction is the extinction of species due to human activities like settlements, hunting, pollution, over-exploitation and habitat destruction. Many species are getting extinct due to deforestation, especially because of the rapid destruction of forests.

Detailed explanation-3: -Extinction can be a natural occurrence caused by an unpredictable catastrophe, chronic environmental stress, or ecological interactions such as competition, disease, or predation.

Detailed explanation-4: -Extinction is a natural phenomenon: After all, more than 90 percent of all organisms that have ever lived on Earth aren’t alive today. But humans have made it worse, accelerating natural extinction rates due to our role in habitat loss, climate change, invasive species, disease, overfishing, and hunting.

Detailed explanation-5: -Species endangerment and extinction have three major anthropogenic causes-overhunting or overharvesting; introduction of nonnative species, including the spread of disease; and habitat degradation or loss. All three causes probably were factors in prehistoric as well as modern times.
