TED-Ed: Whatever happened to the hole in the ozone layer? | Stephanie Honchell Smith
In the 1980s, the world faced a huge problem: there was a rapidly expanding hole in the ozone layer. If it continued to grow, rates of skin cancer could skyrocket, photosynthesis would be impaired, agricultural production would plummet,...
