How does overexploitation affect biodiversity?

Overexploitation means harvesting species from the wild at rates faster than natural populations can recover. Overhunting still poses a big threat to animals in developing regions, particularly primates in Africa. …

How does overexploitation affect the ecosystem?

Overexploiting a species can have detrimental impacts on ecosystem health. Typically, species which are overfished are top predators, and removal of these species changes an entire ecosystem. Additionally, overfishing can directly impact the oceans by destroying habitats with trawl nets.
