Anti-pollution laws began in the 1970s. It’s now been found in Greenland ice cores that lead pollution levels there have dropped by 80% since the 1970s.

In other news, the Chinese government is now searching for two illegal CFC-11 producing factories. These contravene international, and Chinese, law. Their locations have been narrowed to one each in two Chinese provinces by NASA. These may be the last CFC producing factories on Earth, and are certainly the worst producers of atmospheric CFCs on Earth.
