That's not entirely our fault, it is of course in part because of global warming, but there was a volcano that erupted that punched a hole in the ozone layer above Antarctica
The hole in the ozone layer is more our fault than the volcano's. The volcano was what disturbed the ozone layer (it's pretty high up there,) but the reason that the hole didn't naturally close is that we were using CFCs in aerosol cans, and those were destroying so much ozone that the hole stuck around for 25 years and gave penguins cancer. It's literally the only major change we have made in regards to climate change, and it worked! The hole is now almost closed. Moral of the story: you want any real action on climate change? Take UV lamps and give penguins skin cancer. Then the dumb apes will pay attention
you could bludgeon a penguin, a puppy, a kitten, a child to death with a dildo every day in the board room and oil execs would end up cheering if they could make an extra dollar out of it.
