    • Healthy Air is in Our Hands

    Local Air Resources

    Air pollution is a serious threat to human health and livelihoods. Children, older adults, pregnant women, people who spend lots of time outside, and those with lung and heart ailments are among the most susceptible to harm.

    But air pollution isn’t just bad for our health, it’s also bad for the economy. Air pollution can lead to lost work, higher health care expenses, and damage to property and agricultural crops. Poor air quality also can affect tourism and the ability of businesses and institutions to recruit quality employees. With so much at stake, everyone has a responsibility to help keep the air clean and healthy to breathe. Each of us can do something to reduce air pollution.
