What will happen if:
we go on cutting trees.

Options

A. Ecological balance will be disturbed
B. Floods and droughts will become more frequent
C. Many animals will lose their shelters
D. All of these

Explanation

### Step-by-Step Solution:

1. **Understanding Deforestation**:
- Deforestation refers to the large-scale cutting down of trees. This process significantly impacts the environment and the ecosystem.

2. **Disturbance of Ecological Balance**:
- When trees are cut down, the ecological balance is disturbed. Trees provide habitat for various species. The reduction in tree numbers leads to habitat loss, which can cause a decline in species populations, ultimately disrupting the entire ecosystem.

3. **Increased Floods and Droughts**:
- The removal of trees can lead to increased soil erosion. Without trees to hold the soil in place, heavy rains can wash away the topsoil, leading to floods. Conversely, when the land becomes barren, it can lead to drought conditions because there are fewer trees to retain moisture in the soil.

4. **Loss of Animal Habitats**:
- Many animals, including birds, rely on trees for shelter and food. Cutting down trees means that these animals lose their homes, which can lead to a decline in their populations and even extinction of some species.

5. **Conclusion**:
- In summary, if we continue to cut down trees, we will disturb the ecological balance, experience more frequent floods and droughts, and many animals will lose their habitats. All these factors contribute to a negative impact on the environment.
