Air pollution refers to the presence of harmful substances in the air we breathe. These pollutants can have significant impacts on health and the environment.

Common Sources of Air Pollution

• Natural Events: Bushfires, dust storms, and volcanic eruptions contribute to air pollution.
• Household Sources: Burning wood, using gas stoves, and smoking indoors.

Health Effects of Air Pollution

2. Limit Outdoor Activities: Avoid strenuous activities during high pollution periods.
3. Use Air Purifiers: Improve indoor air quality with air purifiers and proper ventilation.
4. Advocate for Cleaner Air: Support policies and initiatives aimed at reducing pollution.
