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?
National Geographic kill humans
National Geographic Don’t build rockets for commercial use? 😂
National Geographic "pollution" very very very broad term there nat geo, but we know who you play for (;

As a chemistry teacher, I couldn't help but notice that chlorine was written as CL and not Cl.
Who cares, you selling yo ? i heard you got the blue stuff
🤓
I used to write CL in my chemistry notebooks till my teacher told me no. I remember writing HE, BE, MG..... I wrote all of them in capitals, haha.

It’s almost unbelievable that we have been able to reverse those effects.
It is unbelievable... because it isn't true! There are still holes in the ozone layer... they never went away. They move and fluctuate all the time through a process we clearly do not yet fully understand. They've most likely been there for millennia. The main factors appear to be solar radiation (as this is how the majority of ozone in the stratosphere is formed) and the jetstreams... as far as we know right now. I think the role of cfc's in the process is probably overestimated.
@San Te Everything you've been fed by people with left-wing agendas and vested interests, you mean. The same people also say global temperatures are controlled by 0.04% (400 parts per million) of carbon dioxide in the atmosphere yet cannot explain how earlier periods when C02 was higher than today were actually colder... there are problematic correlations. And apparently, that massive ball of hydrogen and helium burning at the centre of the solar system has nothing to do with the warming climate. Yet here we are at the Grand Solar Minimum experiencing one of the coldest years globally for several decades. You need to look very hard for yourself to cut through the propaganda if you want the real facts. There's no 97% scientific consensus that global warming is anthropogenic... that's just not true. Ask the physicists, geologists, cosmologists and actual climate scientists. Have a look at the latest data from Greenland ice core samples for example. But don't ask meteorologists who can't even predict the weather three months in advance, never mind three, or thirty, or three hundred years.

I'll be 66 years old when the ozone layer is recovered...i'm 19 now
How do you know
Do you thinck you can live 66 year
Wont be recovered if we continue to pollute the earth. You are 19 and can be a great example or an advocate for anti pollution awareness.

..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....
your a big problem
Mhm "tke" care of it.
- nix- there is billions of other planets like earth but even bigger but I agree we should take care the problem is some people don’t care about earth but most of us care
Um you know there is 50 dwarfs we can go to right
Venus and Mars are dead planets
We should protect our earth first before anything else in the galaxy.

Great video! Love the information that you have provided us!
❤
National Geographic Thanks I am so happy with that News
Thanks for giving such a good knowledge
Straight forward and simple explanation.
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 😄!
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.
It is very informative. Thanks.
Great explanation 👍
Thank you😊
That was the first good prediction I have seen...!!!
This is the kind of information I am looking to learn from this channel. Thanks a bunch!
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.
sennsir_ if only everyone can live with just what they need theres enough for evryone to go around
bulk delivery (amazon) will always be better than individuals going to stores in their car to get the same things (clothes store). Also delivery companies like ups, fedex, dhl can be forced by governments to invest in greener forms of transportation
PixelTrooper i think sennser was talking about the incessant cyclical purchasing that a lot of people have. Buying something that could last for a long time only to buy the “next big thing”. Just look at the trends for buying a new car, phone, “fashion”. Industries have taken it to the point where slight improvements in tech or design are sufficient reasons to get rid of the “old” one and buy a new one. Needs to change fast.
Stevo1361 Ah yeah, i agree on that point, people should use products up until the point they break beyond easy repair or are too outdated. been using my oneplus one for 5 years now and its only just now showing signs of aging
PixelTrooper but the amount of packaging they use is insane! Who needs that much bubble wrap!
It was really informational and eye opener; and gave us a hope that depletion can be controlled.
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.
Yeah he probably discovered the ozone layer. Three different scientist later on found out that CFCs were actually destroying the ozon and that was in 1974.
This really helped me! Thanks!
Amazing video thanks 😊
So that being said will our temperatures rise and or keeping rising? Will we lose winters in some regions? Can we reverse any of the effect in any way? Also if Antarctica will shrink even after we correct what we’re doing and it won’t essentially re-freeze and gain its size back how is it that way in the first place?
Spread the word, make this known!
I love this channel...
Explains better than my teacher..
nice, a mazda commercial right before watch the ozone depletion. Very good thanks for sharing that...................

Does a thinner ozone mean that the polar icecaps reacting to more harmful rays could be contributing to more ice melt?
Shaun-David Fidler that's not true your just trying to scare people😳
Shaun-David Fidler I just did a quick search and apparently, snow is very effective in reflecting UV rays, so I wouldn't necessarily say yes. Although the melting of the polar icecups leads to more carbon dioxide being emitted in to the air which further accelerates the melting of the polar icecaps.
I live in New Zealand which is very close to Antartica and i believe New Zealand has very high rates of skin cancer due to being so close to this hole. the sun in New Zealand is harsh.
ice melt don't matter .. you radiated to death ,.. can't go out side .
he's asking a question. Why do you overreact immediately???@@sarahredwood537
Thanks for knowledgeable video
Thank u very much...
It is very interesting to watch. Expand and open insight into the impact of air pollution caused by nature, namely the combustion system, volcanoes, while there are also human activities in everyday life, fossil combustion systems, gas factories, or vehicles that cause the depletion of the ozone layer. from air pollution, especially CFCs. This is important for the public to know so much that the air pollution produced can reduce the activity of human activity itself and prevent global warming and an increase in the earth's temperature which has an impact on life.
50 years?

Came here for this comment
Much appriciations
I loved the information and what I liked the most was the animation
Please call for leaders and business companies or any concern agencies to act every minute to save our earth
So, How exactly does the Ozone layer recover? I Feel like It’s unrepairable and will only get worse.
It recovers through a natural photochemical process that converts diatomic oxygen to ozone in the stratosphere. Ozone is chemically very reactive, so it quickly reaches an equilibrium where conversion to ozone via solar radiation equals the natural ozone depletion rate (the ozone hole resulted when CFCs accelerated the depletion rate-- the hole appeared over Antarctica due to the Earth's thermodynamics)
no words to tell . the words are still not found
Helpful! ❤️
Is not just by pollution, but the heat of the sun also 1 of the cause
Nooo you cant do that the earth will be too hot!
Sun: haha ozone layer go brrr
thanks....
good explaining for me
It would only fix if we stopped pollution
I would like that kind of sunscreen
superb still research about ozone layer . when the whole will cure . no no no no no words to tell really really very very awesome

Very helpful 💯
this video is sounds and narrated like a science about cat. love it
0:26 Correction: Earth's atmosphere is made up of five layers; not six.
theperfectionist , they didn’t show ionosphere in the video. Including that makes it 6.
Amazing this video ozone hole
If CFC causes holes in ozone layer or makes it thin, why on the poles? Who uses AC, Refrigerator, Sprays in the artic circle?
So CFC emission from NY, Tokyo, HK etc all traveled across the globe to the artic circle where it breaks the ozone molecule.. someone explain this. By this logic ozone holes should have been created on top of temperate zones where CFC should be high.
Ozone (o3 molecule)'s lifespan is very short, 30 mins. So does it matter?
'Most ozone (about 90%) resides in a layer that begins between 6 and 10 miles (10 and 17 kilometers) above the Earth's surface.'
Why flights which fly in the same area not affecting it?
True.
The temperatures and pressure in the polar regions are ideal of ozone depletion.
@@mizzkattie101 so it's expected right. UV radiation is less in Artic and Antarctic poles. Hence less.
CFCs and Chlorine free radicals don't really "rip apart" the Ozone molecule, but other than that this video is very informative and well-done!
It's about scaring people with aggressive trigger words! "A chemical reaction occurs and two new products are created" doesn't sound as spooky. It's on the mend and that's all that matters :)
Wow
Very interesting
You forgot mentioning that there are still problems, like the clear ozone-layer thinning above a region in China, which indicates continued CFC production there. We need to continue raising awareness!
China will be our doom
Wait I thought the ozone layer was healing.....

i love the trolls that think thet are doing something by coming here and trashing everythging Nat geo does when they really make Nat geo money by increasing views and leaving comments and returning to comment again...
The money is channeled for more documentary, archeological, research & developement projects. What else do you know?
True😂
If i remember right, there was before the growing ozone hole massive patent issues about CFCs. When I see a unicorn chasing a polar bear, only then can I say with pride that I have had it all.
thank youu Mam
If ozone layer getting thinner, why don't we use ozone generator such as air purifier to make more ozone ?
Thats bot how it works ozone
making Ozone isn't the problem, making ENOUGH and finding a way to get it all pumped up there is, odds are by the time we figured it out It would have recovered anyways unless we find a way to mess it up
china is still destroying it .. we gonna have to invade countries and save the world ...
Ozone is toxic to us. We need more ozone in the upper atmosphere.
@@cowpoke02 hahahhahaa
No such thing as ozone hole at geographic poles. What we actually have is atmosphere going in and out of polar openings in vortex style just like all other planets with atmosphere. Polar openings are located at 90 latitude, at geographic poles, rotation axis of earth. Read Marshall B. Gardner's book pdf for compelling evidence of polar openings. Ozone = O + Zone. O is a symbol for polar opening. Zone means area. Read between the lines.
Who said ozone isn't a chemical element?
Ozone hole is an illusion created by polar openings. What's actually happening is atmosphere of earth goes in and out of polar openings. Most of atmosphere on the outer earth came from inner earth. Inner earth atmosphere is denser compared to outer earth.
@Food for thought Again nobody said ozone isn't a chemical element. And you understood nothing.
@Food for thought Me trying to create an etymology for the ozone hole fits the bill.
@Food for thought You are confusing ozone chemical with ozone hole.
Good explanation
sangat bermanfaat dan menarik untuk dipelajari, memang benar bahwasanya di planet bumi dikelilingi oleh lapisan ozon yang berfungsi sebagai pembatas antara radiasi ultraviolet bumi dari matahari. lapisan ozon ini tersusun dari lapisan molekul yang reaktif, megandung 3 atom oksigen, dan terdiri dari 6 lapisn. akan tetapi lapisan ozon ini akan rusak dan menipis , adapun apisan ozon menipis disebabkan oleh bahan kimia CFC yang ditemukan pada refrigeran, aerosol, produk plastik, dan bisa juga ditemukan pada polusi kendaraan, pabrik, dll.
very useful and interesting to study, it is true that the planet earth is surrounded by an ozone layer which serves as a barrier between the earth's ultraviolet radiation from the sun. This ozone layer is composed of a reactive molecular layer, contains 3 oxygen atoms, and consists of 6 layers. however, this ozone layer will be damaged and thinned out, while the ozone layer thinner is caused by CFC chemicals found in refrigerants, aerosols, plastic products, and can also be found in pollution from vehicles, factories, etc.
If only i could be a president XD...Id declare ''none shall use fireworks and any more products that can cause great pollution...Or else i will bring back the military base (batas militar)
Im glad tho whenever its night time
You'll need to ban oil company's from making plastic & billions of dollars from such a profit. & then you'll need to stop the nuclear plant on the the coast of ireland from leaking & all the wars in the middle East. But where there's money & power you'll never win .
nvm i hate doing that stuff😂
Hahahhaahhahahah kung ganon lang kasimple
sana nga HAHAHA
I think "batas militar" is more of martial law rather than military base🤔fellow filipino here😂🇵🇭
i thought it is now healing?
We must protect our earth .
Trump would unlike this even before watching it..
Sadly he isn't the only one who has no clue and doesn't care. I mean as long as he has money, he can buy ozone, right? Why should he care? :P
China China China
What's better freeing a nation from cronycapitalism with regulation cuts & job growth by not caring or care and have everyone inslaved ether way we are going down this path together so I hope we will be able to no longer use fossil fuel or coal for electricity and find a better substitute for them we need some Nicola Tesla type thinkers here to fix our grand&great grand parents mistake.
tua domini don't worry too much. Although conservatives usually can be found in the older generations, in the US at least the growth of sustainable energy has overtaken that of the addition of fossil fuels already, whether Trumps administrations likes it or not. The only thing that needs to happen is the replacement of the existing infrastructure.( quick search for example time.com/4662116/renewable-energy-fossil-fuels-growth/ )
Hole above china? Uhh who said the o-zone rotates with earth WTF it would be a missing ring not a hole. For the record yes it rotates with earth but not at the same rate and would still equate to a missing ring not a hole above a specific country.
NASA not long ago said that the ozone layer hasnt Been thicker in over 50 years....
I recently read a statement that it's slowly regenerating (you can see it here: www.nasa.gov/sites/default/files/ozoneposter_front.jpg ) which is probably due to the efforts organizations have been doing to counteract this. Keep in mind though that looking at the images, you can see regular fluctuations that might occur naturally, so be careful not to draw too many conclusions from it.
Also keep in mind facts change really fast, espeically about the climate change. I did a paper on climate change 4 years ago, it said we had like 80 years before any impact, now it's going to 50 years or something.
Lacrosse nah dude. The impact has already taken place. If you're in the US, just look at the coasts of Florida. If you're not, there's countless other examples. 'Before the Flood' is a documentary that shows some places that display this.
Great video!

When I was a kid in 1980s they really scared us with ozone hole. I do not accurately recollect but 1 molecule of Chlorine from CFC will kill 50000 molecules of Ozone due to a chain reaction. Glad to see the hole shrinking.
Sorry, strange question. Does the hole/patch in the ozone happen at both poles the same time or just one side at a time?
Nice, the Ozone layer should recover within a few decades to better than ever before as long as the harmful chemicals remain banned. Good News, I like it.
Then we can concentrate on ground level ozone being the harmful chemical.
www.airnow.gov/index.cfm?action=gooduphigh.index
just gotta keep it out of Trump's hands, if he finds out about this he'll probably unban all of them and then toss in a MAGA for good measure.
@@IonianGarden It is true that CFCs are nontoxic and that incredibly small amounts of ozone can kill a human. However, ozone is great when it's in the upper atmosphere.
