Explanation:
In order to reduce pollution, it is important to take various actions that can help in minimizing the release of harmful pollutants into the environment. The correct answer is option B, which includes actions 1, 2, and 3. Let's discuss each action in detail:
1. Restricting smoking in public areas:
- Smoking releases a significant amount of harmful chemicals and pollutants into the air, such as carbon monoxide, nitrogen oxides, and particulate matter.
- Restricting smoking in public areas helps in reducing exposure to secondhand smoke, protecting people from the harmful effects of smoking and preventing air pollution.
2. Treatment of sewage to remove human waste:
- Sewage contains human waste and various pollutants, including bacteria, viruses, and chemicals.
- Proper treatment of sewage involves removing solid waste, treating the water to remove harmful bacteria and chemicals, and disinfecting it before it is released back into the environment.
- Treatment of sewage helps in preventing water pollution and the spread of waterborne diseases.
3. Using unleaded petrol in cars:
- Leaded petrol contains a high level of lead, which is a toxic metal that can cause serious health problems, especially in children.
- Using unleaded petrol in cars helps in reducing the release of lead into the air, thereby minimizing air pollution and the associated health risks.
4. Spraying pesticides on paints to kill pests:
- This action is incorrect and should not be considered as a way to reduce pollution.
- Spraying pesticides on paints can introduce harmful chemicals into the environment, which can contribute to air and water pollution.
- Additionally, the use of pesticides can have negative effects on human health and the ecosystem, as they can harm beneficial insects and animals.
To summarize, actions 1, 2, and 3 are effective in reducing pollution, while action 4 can actually contribute to pollution. Therefore, option B, which includes actions 1, 2, and 3, is the correct answer.
