Explain any three major causes of biodiversity loss.

1.	Explain any three major causes of biodiversity loss.
Answer» 1. Habitat loss and fragmentation: Many large habitats like forests have been destroyed by Man either for cultivation or for conversion to grasslands and broken up into small fragments which leads to the decline in the population of living organsims. 2. Over – Exploitation: Over – Exploitation of natural resources for the purpose of food, shelter and other purposes and harvesting of many mareine fish populations by humans leads to the elimination of many species. 3. Allien species invasions: Unintentional or deliberate introduction of allien species may cause the decline or extinction of indigenous species as they may turn invasive. 4. Co – extinctions: When a species becomes extinct, the plant and animal species associated with it in an obligatory way also becomes estinct.
