Explanation:
The American Lung Association encourages everyone to get involved in the fight for cleaner, healthier air. Here are some simple, effective tips for protecting you and your family from the dangers of air pollution:
Check daily air pollution forecasts in your area. The color-coded forecasts can let you know when the air is unhealthy in your community. Sources include local radio and TV weather reports, newspapers and online at airnow.gov.
Avoid exercising outdoors when pollution levels are high. When the air is bad, walk indoors in a shopping mall or gym or use an exercise machine. Limit the amount of time your child spends playing outdoors if the air quality is unhealthy.
Always avoid exercising near high-traffic areas. Even when air quality forecasts are green, the vehicles on busy highways can create high pollution levels up to one-third a mile away.
Use less energy in your home. Generating electricity and other sources of energy creates air pollution. By reducing energy use, you can help improve air quality, curb greenhouse gas emissions, encourage energy independence and save money! Check out the U.S. Environmental Protection Agency's easy tips for conserving energy at home.
Encourage your child's school to reduce exposure to school bus emissions. To keep exhaust levels down, schools should not allow school buses to idle outside of their buildings. Many school systems are using the U.S. EPA's Clean School Bus Campaign to clean up these dirty emissions.
Walk, bike or carpool. Combine trips. Use buses, subways, light rail systems, commuter trains or other alternatives to driving your car.
Don't burn wood or trash. Burning firewood and trash are among the major sources of particle pollution (soot) in many parts of the country.
Use hand-powered or electric lawn care equipment rather than gasoline-powered. Old two-stroke engines like lawnmowers and leaf or snow blowers often have no pollution control devices. They can pollute the air even more than cars, though engines sold since 2011 are cleaner.
Don't allow anyone to smoke indoors and support measures to make all public places tobacco-free.
Get involved. Start by checking out our Healthy Air Campaign which has more information about what you can do.
Bottom line: Help yourself and everyone else breathe easier. Support national, state and local efforts to clean up sources of pollution. Your life and the life of someone you love may depend on it.
Answer:
Experience with the Clean Air Act since 1970 has shown that protecting public health and building the economy can go hand in hand.
Clean Air Act programs have lowered levels of six common pollutants -- particles, ozone, lead, carbon monoxide, nitrogen dioxide and sulfur dioxide -- as well as numerous toxic pollutants.
From 1970 to 2017, aggregate national emissions of the six common pollutants alone dropped an average of 73 percent while gross domestic product grew by 324 percent. This progress reflects efforts by state, local and tribal governments; EPA; private sector companies; environmental groups and others.
The emissions reductions have led to dramatic improvements in the quality of the air that we breathe. Between 1990 and 2017, national concentrations of air pollutants improved 80 percent for lead, 77 percent for carbon monoxide, 88 percent for sulfur dioxide (1-hour), 56 percent for nitrogen dioxide (annual), and 22 percent for ozone. Fine particle concentrations (24-hour) improved 40 percent and coarse particle concentrations (24-hour) improved 34 percent between 2000, when trends data begins for fine particles, and 2015. (For more trends information, see EPA's Air Trends site.)
These air quality improvements have enabled many areas of the country to meet national air quality standards set to protect public health and the environment. For example, all of the 41 areas that had unhealthy levels of carbon monoxide in 1991 now have levels that meet the health-based national air quality standard. A key reason is that the motor vehicle fleet is much cleaner because of Clean Air Act emissions standards for new motor vehicles.
Airborne lead pollution, a widespread health concern before EPA phased out lead in motor vehicle gasoline under Clean Air Act authority, now meets national air quality standards in most areas of the country.
State emission control measures to implement the Act, as well as EPA's national emissions standards, have contributed to air quality improvements.
