I've been fortunate enough to visit the future. And I saw the most amazing things. Robots and flying cars were just the start of it. What I saw was the most amazing thing. They created a synthetic ozone molecule, that absorbs CFC and created a new ozone layer that merged with the natural one,allowing O3 molecules to form and the ozone layer to repair itself completely,reversing the effects CFCs had on the atmosphere in our time. Global warming effectively met it's end.
