Which of the following is the most important cause for animals and plants being driven to the extinction?
Habitat loss and frangementation
Drought and floods
Economic exploitation
Alien species invasion
Causes of biodiversity losses -
The accelerated rates of species extinctions that the world is facing now are largely due to human activities. There are four major causes (‘ The Evil Quartet ’ is the sobriquet used to describe them).
- wherein
1. Habitat loss and fragmentation
2. Over-exploitation:
3. Alien species invasions:
4. Co-extinctions
The major causes of the biodiversity loss include habitat loss and fragmentation, alien species invasion, climate change, economic exploitation natural disasters like drought, floods, etc. Among these , the most important cause of extinction is habitat loss and fragmentation. It is caused by deforestation, overpopulation, pollution and global warming. Habitat loss distrups the complex interactions among the species and also kill or force out many plants. With the fragmentation of forest, the species occupying deeper parts are first to disappear.
