Which of the following identifies the two factors thought to be the leading causes of biodiversity loss?

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.
