ozone holes fixed thanks to understanding CFCs, which we failed to do before....
Not a load of crap, we took action on it...it's the perfect example of human action and reaction and what it has achieved.
Don't source wiki
i remember watching a video with scientists' predictions of how ozone holes would progress and it showed almost the entire usa covered by a big hole, and they said that would lead to skin cancer and people going outside only when fully covered. what a load of crap, but at the time it was taken seriously.
in 10 years we'll be laughing about the great global warming scandal, and tax hike excuses will use something else to justify the state's theft of my earnings.
How would we know we fixed it and it wasnt just a natural thing that happened avery 2 zillion years?
Same with this warming cycle, it could be natural, we as an intelligent race have only been here 10 seconds in the clock time that is the world and the universe!
More carbon dioxide feeds the plants, plants produce oxygen.
