Investigate the effect of air pollution on human health by interacting with your elders or community members and identify the main sources of air pollution in your local area. Based on your findings, suggest two practical steps that your school or community could take to help reduce air pollution.

Correct Answer

Expected findings from investigation: Effects of air pollution on human health include respiratory problems like asthma and bronchitis, eye irritation, reduced lung function, and increased risk of heart diseases. Elders may report increased breathing difficulties during high pollution days.

Main sources of air pollution in local areas typically include: vehicle emissions, industrial smoke, burning of waste, construction dust, and burning of fossil fuels for cooking.

Two practical steps to reduce air pollution: (1) Promote use of public transport, cycling, or walking to reduce vehicle emissions.

(2) Plant more trees in and around the school to absorb pollutants and release oxygen.

Additional steps could include creating awareness campaigns, reducing waste burning, and encouraging use of cleaner fuels.
