Original Note:
24 nations signed the Montreal Protocol limiting the use of CFCs in 1987. Scientists estimate that if the Montreal Protocol had never been implemented, the hole would have grown by 40 percent by 2013. Instead, the hole is expected to completely heal by 2050. https://www.smithsonianmag.com/science-nature/ozone-hole-was-super-scary-what-happened-it-180957775/
