The gas released during anaerobic degradation of vegetation may lead to :

Options

A. Ozone hole
B. Acid rain
C. Corrosion of metals
D. Global warming and cancer

Answer

To solve the question regarding the gas released during anaerobic degradation of vegetation and its potential effects, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Anaerobic Degradation**:
Anaerobic degradation refers to the breakdown of organic matter in the absence of oxygen. This process is commonly carried out by microorganisms that can survive without oxygen.

2. **Identify the Products of Anaerobic Degradation**:
During anaerobic degradation, organic materials such as vegetation are broken down, typically resulting in the production of gases. The primary gases produced include carbon dioxide (CO2) and methane (CH4).

3. **Analyze the Impact of CO2 and CH4**:
- **Carbon Dioxide (CO2)**: This gas is a greenhouse gas, which means it contributes to the greenhouse effect. Increased levels of CO2 in the atmosphere can lead to global warming, which is the rise in Earth's average temperature due to the accumulation of greenhouse gases.
- **Methane (CH4)**: Methane is also a potent greenhouse gas, significantly more effective than CO2 at trapping heat in the atmosphere.

4. **Link to Global Warming**:
The release of these gases, particularly CO2 and CH4, during anaerobic degradation of vegetation can contribute to global warming. This is because both gases enhance the greenhouse effect, leading to an increase in global temperatures.

5. **Select the Correct Option**:
Based on the analysis, the correct answer to the question is that the gas released during anaerobic degradation of vegetation may lead to **Global Warming**.

### Final Answer:
The gas released during anaerobic degradation of vegetation may lead to **Global Warming**.
