The air pollution caused by burning of fossils is supposed to result in

Options

A. killing of germs
B. water harvesting
C. global warming
D. lowering of temperature

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the consequences of air pollution caused by the burning of fossil fuels.

2. **Identifying the Main Pollutants**: When fossil fuels are burned, they release various pollutants into the atmosphere, primarily carbon dioxide (CO2).

3. **Effects of Increased Carbon Dioxide**: The increase in carbon dioxide in the atmosphere leads to a rise in the Earth's temperature. This phenomenon is known as the greenhouse effect, where gases trap heat in the atmosphere.

4. **Defining Global Warming**: The gradual increase in the Earth's temperature due to the accumulation of greenhouse gases like carbon dioxide is referred to as global warming.

5. **Evaluating the Options**:
- **Option 1**: Killing of germs - This is incorrect because burning fossil fuels does not kill germs.
- **Option 2**: Water harvesting - This is unrelated to air pollution and is also incorrect.
- **Option 3**: Global warming - This is the correct answer as it directly relates to the increase in temperature due to air pollution from fossil fuels.
- **Option 4**: Loading of temperature - This is incorrect as it suggests a decrease in temperature, which is not the case.

6. **Conclusion**: The correct answer to the question is **Option 3: Global Warming**.
