Earth's ozone layer is gradually thinning out due to pollution. What do you think can be done to slow down the impact of CFCs on our ozone layer?

As a chemistry teacher, I couldn't help but notice that chlorine was written as CL and not Cl.

[randykern]

It’s almost unbelievable that we have been able to reverse those effects.

Ozone : protects from 98% radiation
Rest 2% : *laughs in UV.

National Geographic is better than my science teacher!!!

I'll be 66 years old when the ozone layer is recovered...i'm 19 now

..this is a big problem.. Forget mars forget other planets, WE ONLY HAVE EARTH, THAT'S THE FACT, we have to tke care of it....

With the way that people shop on Amazon, I wouldn't count on that prediction to be accurate. Sadly, fast fashion & the mentality of seeing things as disposable will continue to hurt Mother Earth.

Let’s not forget that the scientist Dobson found out about about the ozone layer in the 1950s and CFCs weren’t really used then so.

We should protect our earth first before anything else in the galaxy.

Great video! Love the information that you have provided us!

[CoobaJ]

A climate video that ends in a happy ending!

[psuedoFREK]

Thank you for the insightful video. I think it's a testament to the good will of humanity that delegations were able to reducethe usage of Cfc emitting products to the degree that a global crisis has been averted before it caused too much damage.

[JaffaBuiscits]

Does a thinner ozone mean that the polar icecaps reacting to more harmful rays could be contributing to more ice melt?

[AbirChoudhury]

This is the kind of information I am looking to learn from this channel. Thanks a bunch!

[younesbesseghir]

101 is the best of all!! I tried to find an answer for a lot of questions and to gain more knowledge about everything but google was not enough 😄!

[hinkalhellokitty]

It was really informational and eye opener; and gave us a hope that depletion can be controlled.

[sanketpatil]

That was the first good prediction I have seen...!!!

[hashirbp]

I love this channel...
Explains better than my teacher..
