China’s Air Pollution Hits the U.S.
Particulates in the air can travel thousands of miles. Polluted air in China can actually reach California, depending on weather patterns.
On estimate suggests that one-third of San Francisco’s air pollution actually comes from China. Plus, the five U.S. cities with the highest air pollution rates are all in California. As a result, even if the U.S. makes good choices about lowering pollution, other countries’ decisions can still lead Americans to breath polluted air.
