The ALA suggests the following for lowering pollution in your community:
Use less electricity. Generating electricity is one of the biggest sources of pollution, particularly in the eastern United States.
Don't burn wood or trash. Burning firewood and trash is among the largest sources of particle pollution in many parts of the country. If you must use a fireplace or stove for heat, convert your woodstove to natural gas, which has far fewer polluting emissions.
Make sure your local school system requires clean school buses. Make sure your local schools don't idle their buses, a step that can immediately reduce emissions.
