I first heard about the ozone¹ layer about twenty years ago. I was still in school. I thought it was interesting, but I didn’t take it seriously. It was a bit like science fiction, I mean, how could there be a giant hole in the atmosphere? Over the years, more and more scientists spoke² about the ozone layer. Global warming became a serious issue. Important people like Al Gore³ made movies about it. We all know today that the thinning ozone layer is perhaps the most serious crisis⁴ we face today. Even though many people have changed their lifestyles, we are still damaging the ozone layer. We need to do something really drastic⁵ to stop this. We all need to stop driving cars and stop using coal. That would be a start.
