Did you know that turning off the lights is part of the best solution to control air pollution? Power plants must generate electricity by either nuclear reactions, or by burning fossil fuels. Every time you leave the light on in the basement, more fossil fuel must be burned to keep that light on, and more pollution is put into the air as a result. To effectively control air pollution, it's necessary to reduce the amount of fossil fuels being burned. The next time you hit the light switch, remember that you are directly contributing to the air pollution solution.
