We’re always hearing that the ozone1 layer is being depleted2, and how bad this is because we need it to protect us from the sun’s harmful ultraviolet rays. But I’ve been thinking, and there has to be a more effective way to restore the ozone layer than by sitting around not releasing any more harmful chemicals into the air so the ozone has a chance to repair itself. Ok, like what? Well,how hard could it be to make more ozon? We must have plenty of raw material. After all the ozone molecule3 contains three oxygen atoms–and the oxygen molecules4 we breathe contain two oxygen atoms, so can’t we just use that oxygen to produce a bunch of ozone ourselves and stick it back up in the atmosphere?
