What are some threats to biodiversity?

The core threats to biodiversity are human population growth and unsustainable resource use. To date, the most significant causes of extinctions are habitat loss, introduction of exotic species, and overharvesting. Climate change is predicted to be a significant cause of extinctions in the coming century.

Here are some examples:

1. Human Activities and Loss of Habitat

2. Deforestation

3. Desertification

4. Marine Environment

5. Increasing Wildlife Trade

6. Climate Change
