Human activities harming air quality:
- Industrial emissions: Factories and industries release harmful pollutants like sulfur dioxide, nitrogen oxides, and particulate matter into the air.
- Vehicle emissions: Exhaust from cars, trucks, and other vehicles contribute to air pollution with pollutants such as carbon monoxide and volatile organic compounds.
- Deforestation: Cutting down trees reduces the amount of oxygen produced and increases levels of carbon dioxide in the air.
- Burning fossil fuels: Coal, oil, and natural gas combustion releases greenhouse gases like carbon dioxide, contributing to global warming and climate change.

Conservation measures for air quality improvement:
- Reduce vehicle emissions: Use public transportation, carpool, bike, or walk whenever possible to reduce the number of vehicles on the road.
- Use energy-efficient appliances: Switch to energy-efficient light bulbs and appliances to reduce the amount of electricity generated from fossil fuels.
- Plant trees: Trees absorb carbon dioxide and release oxygen, helping to improve air quality.
- Support clean energy: Invest in renewable energy sources like solar or wind power to reduce reliance on fossil fuels.
- Reduce, reuse, recycle: Minimize waste production and recycle materials to reduce the need for energy-intensive production processes.
- Support air quality regulations: Advocate for stricter regulations on industrial and vehicle emissions to protect air quality.
By implementing these conservation measures, we can work towards preserving air quality for the betterment of the environment and human health.
