Everyone in Los Angeles breathes the country's worst air, but residents in some L.A. neighborhoods are poisoned in their own homes, when they go outside to tend their gardens or walk their children to school. Pollution-linked illness is 2 to 3 times higher in neighborhoods in East and Southeast Los Angeles, parts of the San Fernando Valley and communities surrounding the Ports of L.A. and Long Beach. 

Liberty Hill environmental investments target low income communities of color where L.A.'s pollution has its most deadly consequences. Improving the environment in these densely polluted neighborhoods benefits every one in Los Angeles, but most of all, the tens of thousands of families who are being choked by truck and train pollution, factory toxins, and ship and plane exhaust every day.

Scientists call this concentrated exposure to environmental pollutants "cumulative impact." Liberty Hill calls it a matter of life and death.

Right now, the Clean Up Green Up campaign, which received significant support from Liberty Hill, is moving a policy through City Hall that would transform some of the city's toxic hotspots into Green Zones. Find out more at the Clean Up Green Up website.

For more than 20 years, Liberty Hill has played a leading role in L.A.'s environmental justice movement.
