What are the advantage of keeping the air and water clean?
Cleaning up our air also yields great savings. For every air pollution standard, the EPA monetizes benefits that come from preventing bad things from happening, such as heart attacks avoided, ER visits avoided, lost work days avoided, and deaths avoided. The benefits are enormous.
Why is it important to maintain clean and unpolluted air in our community?
Clean outdoor air needs to replace indoor air often or else the indoor air becomes more polluted. Otherwise allergens, smells and pollutants stay in your home and recirculate. Because newer, more energy-efficient homes don’t have the same gaps and cracks as older homes, there’s less air circulation.
What are effects of air pollution?
Long-term health effects from air pollution include heart disease, lung cancer, and respiratory diseases such as emphysema. Air pollution can also cause long-term damage to people’s nerves, brain, kidneys, liver, and other organs. Some scientists suspect air pollutants cause birth defects.
