- What do you want me to do?

Man-made air pollution mainly comes from two sources: mobile ones and stationary ones. Mobile sources are cars, planes, boats, etc. Stationary sources include large factories, power plants and every household, which burns natural gas or wood. The most important ways to reduce air pollution are to drive less, use less electricity and natural gas, and eat vegetarian.

These ideas are easy to follow:

1.Get your car checked regularly to make sure everything works properly. Whenever possible, walk, cycle, carpool, or use public transportation. Buy fuel-efficient vehicles. Drive at 60 mph or less to improve gas mileage. 

2.Burn less natural gas to cook or heat your home. Instead, use a solar cooker or heater and wear extra layers.

3. Become a vegetarian or a vegan. Raising any sort of livestock requires more land and emits more carbon dioxide than simply growing crops directly for human food.

4. Use less electricity. Coal power plants produce most of the world’s electricity, and they also produce more carbon dioxide than any other source. Coal plants also release many other pollutants. Unplug televisions, cell phone chargers, and other appliances while not in use. Most devices continue to use small amounts of power even when they’re turned off. Avoid using air conditioning, and don’t leave the fridge open any longer than necessary. Only run the clothes washer or dish washer when full. Rather than using a dryer, hang clothes on a line to dry in the sun.
