This type of biodiversity loss is known as one of the most critical threats to global biodiversity. The possible causes include habitat destruction and modification, diseases, exploitation, pollution, pesticide use, introduced species, and ultraviolet-B radiation (UV-B). However, many of the causes of amphibian declines are still poorly ...
Like human-predator in Africa, encounters between tigers, people, and their livestock is a prominent issue on the Asian continent. Attacks on humans and livestock have exacerbated major threats to tiger conservation such as mortality, removal of individuals from the wild, and negative perceptions of the animals from locals. [19]
This may explain why human population density accounts for 87.9% of the variation in numbers of threatened species across 114 countries, providing indisputable evidence that people play the largest role in decreasing biodiversity. [18] The boom in human population and migration of people into such species-rich regions are making conservation ...
The key threats identified to species were pollution, overfishing, agriculture and invasive species, particularly the Nile perch and water hyacinth. Lake Titicaca is situated on the border between ...
Biodiversity loss is in fact "one of the most critical manifestations of the Anthropocene" (since around the 1950s); the continued decline of biodiversity constitutes "an unprecedented threat" to the continued existence of human civilization. [61] The reduction is caused primarily by human impacts, particularly habitat destruction.

Overexploitation is one of the main threats to global biodiversity. [3] Other threats include pollution, introduced and invasive species, habitat fragmentation, habitat destruction, [3] uncontrolled hybridization, [37] climate change, [38] ocean acidification [39] and the driver behind many of these, human overpopulation.

Human impact on the environment (or anthropogenic environmental impact) refers to changes to biophysical environments [14] and to ecosystems, biodiversity, and natural resources [15] caused directly or indirectly by humans.
