Question
How does over-exploitation of beneficial species affect biodiversity?
✓
Answer
Humans depend on nature for food and shelter.
But over-exploitation of natural resources has led to extinction of many species in the last 500 years, e.g. Stellar's sea-cow and Passenger pigeon, are lost due to over-exploitation.
Many marine fish populations around the world are over-exploited, thus endangering the continued existence of some commercially important species.
