Which factors involving the activities of people are a threat to biodiversity? pollution and succession habitat loss and predation poaching and habitat loss succession and poaching

Both poaching and habitat loss are a threat to biodiversity

Habitat loss refers to the destruction of natural ecosystems and consequent reduction in the amount of habitat available for the species living in a given area. Habitat loss is the greatest threat to ecosystems biodiversity and conservation worldwide by deteriorating natural areas and thereby reducing species distribution ranges. Habitat loss is primarily due to the expansion of human populations and human activities (i.e., mining, logging, trawling, industrial production, urbanization, etc.).  

Poaching refers to the illegal killing of wild animals for different reasons (e.g., meat, recreation, etc.), in violation of international, federal, state/provincial, or local laws. Poaching can drastically reduce the number of organisms in natural populations, thereby this human activity can reduce genetic diversity and eventually may lead to the extinction of natural populations/species.

In conclusion, both habitat loss and poaching can reduce the number of organisms, reduce biodiversity and eventually cause the extinction of natural populations.
