6. Confirmation of the Ozone Hole (1985):
Discovering the ozone hole was a big deal that got scientists all over the world talking. Back in the 1980s, they noticed that the ozone layer over Antarctica was getting thinner, and that’s bad news because the ozone layer helps protect us from harmful UV rays.
This finding led to a global agreement called the Montreal Protocol in 1987, where countries agreed to stop making things that were messing with the ozone layer.
As time went on, satellites and more research confirmed that the ozone hole was still a thing, making everyone realize how important it is to work together to keep our planet’s atmosphere in good shape. The ongoing efforts to fix the ozone layer show that when people team up, we can make a positive impact on the environment.
