    In the ’80s, scientists discovered there was a hole in the ozone over the South Pole. A significant layer of gas that deflects much of the sun’s radiation was disappearing much faster than anyone expected. Projections suggested it would collapse by 2050, increasing skin cancer rates, harming crops, and destroying the marine food chain. The situation was dire. But today, we are on the path to recovery.

    Dr. Susan Solomon, among other scientists, contributed key findings to understand what was depleting the ozone layer and how to address it. In this video she takes us back to her expedition to Antarctica, breaks down how we managed to fix this huge problem, and looks at our next big environmental challenge — climate change — with the unbridled optimism that drove her to fix the ozone hole.

    Hi! Christina here — I wanted to share NASA’s World Avoided scenario with you. As a child of the ’80s, the threat of the ozone hole was always something I was aware of, but this model really helped me understand the catastrophe we would’ve faced had we ignored it: https://earthobservatory.nasa.gov/features/WorldWithoutOzoneThanks so much for watching our video! Let us know what you think in the comments below.

    In movies we see actors and actresses saying we gotta save the world. They actually saved the world in reality. But the heat is still increasing. Every year it's a record for highest temperature. Usually it's cold in December were in live. But today it feels normal like any other day.

    Yeah, how about "acid rain" back in the 70's? Its always some catastrophe that is pumped up by the news media. Ever hear of influenza? Yeah, a mutation is now labeled as a "variant" now because it sounds new age and sexier. Yeah.....

    Why did all the cfcs go down to the South Pole? if most of population is on other continents. shouldn’t have the ozone layer in those places be affected more?

    Switching CFC to an alternative is much more practical than any climate change proposal raised nowadays.

    I was waiting for the pandemic to be mentioned. I read in a news some months or a year ago, that the ozone's been healing faster due to the global pandemic's restrictions. Less people go outside and using stuff that damages the ozone.

    Literally , when I was in 10th standard , I had thought there is a hole in earth 🌍 surface , from where the O3 ( ozone ) is releases.😅

    I thought this was going to be, “we were all wrong, we went nuts over some normally occurring phenomenon.” Instead the story is “we did good.”

    With woke and cancel culture that we have today, we could have never achieved it. Glad people listened to what scientists said.

    LOL complete garbage! Fodder for those who are easily scared and manipulated. They only use the "science" that supports their narrative. Can't believe many of you fall for these scams.

    Or maybe we are in another earth have you thought about that? Some of us are still sleep. But some others are in a future mode of consciousness to help and uplift humanity to a different frequency Mentality and then you have those bad who have had tried to stop it. Nevertheless in this earth that stuff is not going to work because humanity doesn't want anymore wars. Together we are building a better world. Look inside and find your pure essence of who you are and where you come from

    How come we seldom hear anything about the greening of the planet? Oh! I know, it’s probably because we can actually see that it’s growing and the alarmists prefer to focus on things we cannot see. Just sayin!!!

    Only 100 companies around the world are responsible for 70% of climate change. Capitalism is the reason we must change the global economic system in order to address many problems, not only poverty but climate change, especially the plant system. It helps and reduces the number of births. It helps and changes the pattern of industry, recycling and lifestyle. In general, the extraction of lithium for electric batteries may be worse than the extraction of petroleum

    I like how she said Practical. Climate change requires far too much public support, for Ozone, it was rejecting CFC and companies used an alternative. Phasing out gas powered cars, machines, meat industry etc is definitely a bigger challenge, but thanks for putting this together, Vox ! It gives us hope that we have come together for mother earth once and we will do it again.

    I think the reason why they didn’t tell anyone was to keep people more green. If everyone knew the ozone was healing, they wouldn’t work so hard to recycle anymore and then they would just take advantage of it.

    Hey, woke up and fed up now, not seeing and feeling change? Doing what you can do be a better partner? A human being. Yet still not enough? Taking personal counselling, Continuing to pray 🤲🏾 trying to keep yourself humble and spiritually, hiding the pain hoping things will change for the better. But physically and mentally it hurts lord I pray I work as hard as you believe in us to come together baby 🙏🏾❤️😇

    I guess she needed to add a fourth P to the story: Producers. Back then they directly attacked the producers of the chemical, and therefore went straight to the source. These days the narrative is aimed at the consumers and personal responsibility, a narrative invented by stakeholders such as BP. This ensured that for decades the big players stayed out of the picture. Change isn't possible if that remains the case.
