NEET BIOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -There is no question that overexploitation has led to species extinctions in historic as well as modern times. Unsustainable hunting, fishing, logging, or gathering of wild populations leads to their commercial, ecological, or global extinction.

Detailed explanation-3: -Often overexploitation occurs when natural populations are harvested for food. A classic example was the persecution of the passenger pigeon, which once was the most abundant bird in North America.

Detailed explanation-4: -Passenger pigeon and stellar sea cows have become extinct because of over-exploitation. Over-exploitation means harvesting species from the wild at rates faster than natural populations can recover. Over-fishing and over-hunting are both types of over-exploitation.

Detailed explanation-5: -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.
