Do parks reduce pollution?

City parks help clean the air and improve public health. Trees in urban parks remove up to 711,000 tons of toxins from the air annually at a value of $3.8 billion to cities. Green spaces also filter rain, reducing water pollution, protecting drinking water, and decreasing the rates of waterborne illness.
