United Nations Says Earth's Ozone Layer Is Repairing

An anonymous reader quotes a report from the BBC: The ozone layer, which protects us from ultraviolet light, looks to be successfully healing after gaping holes were discovered in the 1980s. The Northern Hemisphere could be fully fixed by the 2030s and Antarctica by the 2060s. A new United Nations report says it's an example of what global agreements can achieve. The ozone layer had been damaged by man-made chemicals called chlorofluorocarbons (CFCs). The chlorofluorocarbons (CFCs) effectively began eating away at the ozone. CFCs were found in things like spray cans, fridges, foam insulation and air conditioners. As a result, in 1985 a gaping hole in the ozone over the South Pole was discovered. An international agreement called the Montreal Protocol made sure that businesses came up with replacements for these damaging products. 180 countries signed up to it. In signing the protocol, those countries agreed to phase out chemicals like CFCs.
