How can overexploitation cause extinction?
Overexploitation or overfishing is the removal of marine living resources to levels that are too low for sustaining viable populations. Ultimately, overexploitation can lead to resource depletion and put a number of threatened and endangered species at risk of extinction.
What does overexploitation cause?
Prized fish, such as swordfish, cod and tuna, have undergone dramatic declines. In the Great Lakes, overfishing has caused whitefish, walleye, and sturgeon populations to decline.

Destruction of Habitat – It is currently the biggest cause of current extinctions. Deforestation has killed off more species than we can count.
What human activities cause extinction?
Human activities that influence the extinction and endangerment of wild species fall into a number of categories: (1) unsustainable hunting and harvesting that cause mortality at rates that exceed recruitment of new individuals, (2) land use practices like deforestation, urban and suburban development, agricultural …
