I didn't think the ozone layer could recover, and that 101-year-old man is a badass.
Well, when you take measures to prevent the destruction of the environment, as we did by banning the chemicals that were destroying the ozone, the planet is fairly good at mending itself. We could fix almost all of today's environmental problems too, if we just made the necessary effort. The ozone's recovery shows we can do it when we try, and to me that's cause for hope.
And indeed he is.
Bet with Liquidlaser: I say PS5 and Xbox Series will sell more than 56 million combined by the end of 2023. (And over 130 million lifetime)
