Atmosphere does not get polluted by

Options

A. mining
B. farming
C. transportation
D. manufacturing

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which activity does not pollute the atmosphere among mining, farming, transportation, and manufacturing.

2. **Analyzing Mining**: Mining involves extracting minerals from the earth. This process can release dust and harmful gases into the atmosphere, contributing to air pollution. Therefore, mining does pollute the atmosphere.

3. **Analyzing Farming**: Farming, or cultivation, involves crop production. While farming can lead to some environmental impacts, such as pesticide use and soil degradation, it does not directly pollute the atmosphere in the same way that the other activities do. Thus, farming is the activity that is least likely to pollute the atmosphere.

4. **Analyzing Transportation**: Transportation involves the use of vehicles that burn fuel. This combustion releases smoke and harmful gases, such as carbon dioxide and carbon monoxide, into the atmosphere, leading to air pollution.

5. **Analyzing Manufacturing**: Manufacturing processes often involve factories that emit smoke and other pollutants into the atmosphere. This includes emissions of carbon dioxide and other harmful gases, contributing significantly to air pollution.

6. **Conclusion**: Based on the analysis, farming is the activity that does not significantly pollute the atmosphere compared to mining, transportation, and manufacturing.

**Final Answer**: The atmosphere does not get polluted by farming.
