If you ever feel like humanity can't be united to work together on issues like climate change, keep in mind that similar crisis have occured before, and we've successfully solved them: one great example is the ozone hole which was first discoverd in 1980s! There used to be a hole in the ozone layer and everyone talked about it. What happened? Our collective effort happened to ban one of the main culpids responsible for depleting the ozone layer. What's the status now? #inanutshell #kurzgesagt #ozone #ozonelayer #earthfact #climatechange #climateaction
