Yes, we actually have some good news to report about the environment. The United Nations has issued a report with NASA photos showing that the giant hole in Earth’s ozone layer is shrinking. The ozone layer protects us from the sun’s harmful ultraviolet rays and was being destroyed by the use of chlorofluorocarbons (CFCs). Over vehement objections from industry that curtailing CFCs would destroy the economy, new laws forced the use of substitutes and the result has been predictable and encouraging.
Industry fought to stop the ban on CFCs for decades even though scientists linked CFCs to the ozone depletion in the 1970s. In 1987, the world reached a phase out agreement as part of the Montreal Protocol. Industry and various politicians denounced the agreement as a disaster for the economy and jobs. Instead, it quickly forced the creation of alternatives, which are now in wide use.
Here is the result:
It is not done however. It will take until 2050 for the ozone layer in the mid-latitudes to return to relatively healthy 1980s conditions. Around the Antarctic, where the ozone layer is the most damaged, it will take until 2075. However, humans actually made a sacrifice and produced a beneficial result for their planet. Now that is worth celebrating.
