20 Harmful Human Activities Towards Air:
- Industrial emissions
- Vehicle exhaust
- Deforestation
- Agricultural activities (e.g. burning of crop residue)
- Burning of fossil fuels
- Landfills and waste disposal
- Construction and demolition
- Mining activities
- Use of household chemicals
- Smoking tobacco products
- Open burning of waste
- Aerosol sprays
- Air travel
- Use of coal for energy production
- Oil and gas extraction
- Forest fires
- Indoor cooking with solid fuels
- Use of wood-burning stoves

- Incineration of waste

Methods to Conserve Air:
1. Reduce Industrial Emissions: Implementing cleaner production techniques and using renewable energy sources.
2. Promote Sustainable Transportation: Encouraging the use of public transport, cycling, and walking to reduce vehicle emissions.
3. Planting Trees: Trees help absorb carbon dioxide and release oxygen, improving air quality.
4. Proper Waste Management: Recycling and composting waste instead of burning it can help reduce air pollution.
5. Regulate Agriculture Practices: Encourage farmers to adopt sustainable farming methods that reduce air pollution.
6. Use Clean Energy Sources: Transitioning to renewable energy sources like solar and wind power can reduce air pollution from fossil fuels.
7. Reduce Household Chemical Use: Opt for eco-friendly cleaning products and avoid using harmful chemicals indoors.
8. Support Air Quality Regulations: Advocate for stricter regulations on air pollution from industries and vehicles.
9. Raise Awareness: Educate the public about the importance of clean air and the impact of their actions on air quality.
10. Invest in Air Purification Technologies: Use air purifiers in homes and workplaces to improve indoor air quality.
