B. Harm to groundwater
C. Global warming.
D. All.

Answer

### Step-by-Step Text Solution:

1. **Understanding Deforestation**:
- Deforestation refers to the large-scale removal of trees from forested areas, which can lead to significant environmental changes.

2. **Consequences of Deforestation**:
- **Desertification**: The removal of trees can lead to the degradation of land, turning fertile areas into deserts. This occurs because trees play a crucial role in maintaining soil quality and moisture.
- **Harm to Groundwater**: Trees help in maintaining the water cycle. When trees are cut down, the ability of the land to retain water decreases, leading to reduced groundwater levels.
- **Global Warming**: Trees absorb carbon dioxide, a greenhouse gas. When they are removed, the concentration of carbon dioxide in the atmosphere increases, contributing to global warming.

3. **Conclusion**:
- Based on the consequences discussed, the correct options that represent the consequences of deforestation are desertification, harm to groundwater, and global warming.

### Final Answer:
- The consequences of deforestation include:
- Desertification
- Harm to groundwater
- Global warming
