Where does the damaging gases of the ozone come from?

It comes from us humans being careless and selfish about the enviroment because of the waste we produce every day. Such as emissions from vehicles, production plants/factories etc.. Ges that rise to the ozone with harmful contaminates that attck the ozone layers, then weakening it and allowing more of the harmful Ultra Violet rays from the sun to come into earths atmosphere. Then causing global warming and polar ice caps to melt and water levels rising and climates increase in temperatures etc.. Global Warming is a real thing happening. We seriously need to take action to prevent further damage. You can start at home by just Recycleing and buying recycled products.
