It is rather incredible to think about. The entire world came together in peace to protect their common home. We all came to conclusions based in scientific principles that have been developed over decades, centuries and millennia of time.
It was one of the greatest times in modern history. Earth's ozone holes brought all of us together in one effort and it works. It has to continue to work and the gases that place all of us in danger, even if it is only skin cancer that is the result. The Ozone Layer is very important and crops need it for protection as well as people. All living things, including animals and wildlife, need the protection of O3. Three atoms of oxygen. Amazing.
