What are the causes of biodiversity loss explain each with the help of examples?

Biodiversity loss is caused by five primary drivers: habitat loss, invasive species, overexploitation (extreme hunting and fishing pressure), pollution, climate change associated with global warming. In each case, human beings and their activities play direct roles.

Habitat destruction is a major cause of biodiversity loss. Habitat loss is caused by deforestation, overpopulation, pollution, and global warming. Species that are physically large and those living in forests or oceans are more affected by habitat reduction.
