What is the main cause for the extinction of some species in tropical forest?

Options

A. Deforestation
B. Afforestation
C. Pollution
D. Soil erosion a

Answer

### Step-by-Step Solution:

1. **Understanding Tropical Forests**: Tropical forests, particularly tropical rainforests, cover about 16% of the Earth's total forest area. They are known for their rich biodiversity and high nutritional content in the soil.

2. **Identifying the Main Cause of Extinction**: The main cause of extinction for some species in tropical forests is primarily deforestation. This involves the large-scale removal of trees and vegetation.

3. **Human Activities Leading to Deforestation**: Human activities such as urbanization, road construction, and agricultural expansion are significant contributors to deforestation. These activities lead to the clearing of large areas of forest, which directly impacts the habitats of many species.

4. **Impact of Deforestation on Biodiversity**: The reduction of forest area from 16% to about 6% has severe consequences for biodiversity. As habitats are destroyed, many species lose their homes and food sources, leading to their extinction.

5. **Exclusion of Other Factors**: While pollution and soil erosion are concerns in many ecosystems, they are not the primary causes of species extinction in tropical forests. In fact, the dense vegetation of tropical rainforests helps to prevent soil erosion.

6. **Conclusion**: Therefore, the main cause for the extinction of some species in tropical forests is deforestation driven by human activities.
