Coral reefs cover less than one percent of the seafloor, and yet they’re home to a quarter of all marine life, making them some of the most biodiverse places on Earth. But their future looks bleak. Decades of environmental threats like warming waters and ocean acidification have pushed reefs to the brink. Can we use science to bring them back?

your puns are getting worse per video!
i love it.
Daan van Dongen hahahahhahahahahhaha
I don't care how long it takes, people need to revive coral reefs
I wanted too become a marine biologist someday and this is one of the reasons why.
I hope you do. Good luck!
Me too!
Lol thx
"To two too" said the grammarsaurus.
It's a tough and gueling journey. But, if u really love it then you will endure it no matter what!
im so happy that channels like these really educate us well about our climate and how to prevent climate change :)
And this is why I want to become a marine biologist.
Great video!! Thank you!!
Good luck! The corals need you
I'd like to expand on the answer: All marine life needs you. Bonne chance.
Thank you very much, guys. Hopefully I will be of some benefit to all marine life - and, thus, to all life on Earth. And good luck to anyone else starting out on the same endeavour!!
Good luck earth needs you
Thought I was the only one with this reason! Gogo go go!
Thank you, this helped me with a school essay🙏🏾
This channel needs way more subscribers! Thanks for the awesome video.
Nice animation, even nicer information. Thanks for uploading videos like this, both ur channel r awesome. You made my day, once again, thanks.
Great video as always
Hot mess videos are very informative & knowledgeable ! Way to go Team PBS
Every coral reef may also serve a porpoise. Great episode. Thanks for sharing!
One thing that was both shocking and enlightening was to learn the paleontological record for coral namely how coral reefs have convergently evolved numerous times only to get wiped out in subsequent mass extinctions bringing disastrous circumstances for what species had lived at the time. And never before has one species been the driving force behind a major mass extinction, all of them required the concurrence of multiple coinciding disasters both to push life to the brink and then drop it off the edge. We have somehow in our short sighted arrogant greed as a species found a way to do both...
That’s why they call us the 6th mass extinction event
We truly are horrible, but we must not let the greed and ignorance of a few destroy our beautiful home.
@@jordanz4264 The Great Barrier Reef is one of the planet’s natural jewels, stretching for more than 2,300km along Australia’s north-east.
But as well as being a bucket-list favourite and a heaving mass of biodiversity across 3,000 individual reefs, the world heritage-listed organism is at the coalface of the climate crisis.
Yet this week, a report on the amount of coral across the reef showed the highest level in the 36 years of monitoring in the north and central parts.
Glaring so hard at that pun right now.
Hey Joe, this is a very great video!! I wanted to let you know about something called coralliths. They can also potentially help restore reefs!
It's super informative thank you so much
this really helped me to do my speech for school
Would have liked to see the effects of disease carrying plastics on corals included. I know this channel is specifically about warming, but related issues like pollution from petroleum products seems relevant. Do the grown corals resist diseases carried by plastic pollution better than wild counterparts? Are the chemicals in plastic affecting coral reproduction like with other animals?
love the vid bro !!!!!!!!!
Love this channel
very good explain .
Thank you for the great video
Grats on the 69k subs
This is one of the more hopeful videos on climate change I have seen today. good work guys!
Flora & fauna of the sea is just as precious and ethereal as that on land. Both must be protected and conserved at all costs. 😌
Thank you
A Labour of Love 🤲🪸
Most underrated PBS channel after Infinite Series. Content Quality is quite high. Unfortunately people fail to realise that.
Awesome video !!
And 5 th 😯
Wait until Jotaro hears about this
We can use molten salt reactors to reverse ocean acidification or to create carbon neutral synthetic fuels. Please make a proper video about advanced fourth generation nuclear power
I'm so depressed that my favourite place is dying
Porpoises, dolphins, and ex-Trumpies: all Flippers
Thank you scientists
Please save us from stupid ignorant people
Many years ago, electrified metal grids were used to quickly create coral reefs to stimulate fish breeding and create habitats. Couldn't that be used to restore coral formations that have been harmed by warmer water?
Nice video! Unfortunately coral reforestation has no sense if Environmental conditions are not the proper
Thanks for a hopeful outlook on a hard topic. Rather than being discouraging and grim, you give ideas and encouragement.
What about breeding projects? Yes DNA manipulation is cool and all, can we breed varieties of coral to withstand harsher conditions and demands?
Why not seed artificial coral reefs in cooler waters?
Individually gluing pieces of coral onto dead reefs could only help a tiny area just because of the impossibility of people being able to physically cover 70% of the planet. But we might as well try everything we can.
Zom Bee Nature. Remember that coral reefs only cover less than 1% of the sea floor

What if we could genetically modify the algae to work the same way in warmer temperatures? And as a safety mechanism, only be able to live a short time outside the specific host coral. So that they don't do more harm than good. Could that work?

What I find an interesting way to point out the reality of climate change to people, is through showing the interrelated ways everything is affected. It's easy for anyone to think it's fiction because the reality sounds dramatic, but only because we don't see the bigger picture. It's really simple: one thing affects another. So it should be obvious that anything we do, has some kind of a consequence. Once people understand that, it's easier to convey the reality like videos such as this one.
Coral are not endangered of extinction. Once the sixth great mass extinction is over the few coral specials that survived will evolve into new forms as they take on new environments and whatever else survived the mass extinction.
...puns are my purpoise in life...
Similarly make a video on rainforests.
i need some sources
Lol, I don't think there are many pikes in the coral reefs..
I'll tell you what it is... It's evolution baby!
Someone pour a BUNCH of tums into the ocean
Wow ocean acidification is a very very backburner issue for coral. I don't like that you brought it up. The heat from the CO2 is an issue way way before the acidification. Almost not even worth mentioning.
Why not glue fake colorful coral to the sea bed? My mom uses fake flowers all the time.
Needs the taps turned off filling the atmosphere with C02 whilst taking up more C02 by planting more trees, hemp, vertical sea farms et al until C02 and methane reduces. On personal, political and collective levels.
Even in this channel Joe makes puns.
Wana cry when seeing whole see ecosystems around me dead.
The reefs are fine

Coral reefs are not dying! Bleached coral is a temporary phenomena that the reefs quickly recover from. Since most of the worlds corals live in the warmest tropical waters and it is known that during periods in earths history when oceans were warmer that coral reefs flourished, then how can warmer water be killing them? It makes no sense but does appeal to scientists emotionally attached to their anthropogenic climate change models and also gives them lots of grants due to the interest their catastrophic predictions generate.
Can Hot Mess tell us science, climate change information hungry viewers about cold water corals? They seem to get forgotten compared to the stony corals that are more visible. Maybe not as susceptible as they don't need zooxanthellae to survive, but they are still at risk from us pesky upright apes!
we should use genetic engineering to create highly resistant strains of existing species
I meditate to save them
Even if coral reefs can adapt to a changing world, the animals on the polar ice caps won't evolve to a warming world. The world shouldn't warm.
Just commenting to help the algorithym
Sorry mostly dead already this summer predicted mmmm bad mildly put.
Hi 2nd
Ima be dead by 2100 soooooooo
Nice animations...
Enjoy the collapse.
See: Chasing Coral www.chasingcoral.com/
I love how people say "overfishing' like there's some magical non-zero amount of suffication, torture and polution acceptable because "it tastes good"

Could you drop videos more frequently plz? Rather than uploading 1 per week it would be better if you could upload 2 per week.
Kabirul Hassan says the commenter who barely has any idea how much work goes into each video. Just be grateful ffs
@@MiracleWinchester well if i like the channel i can definetly ask for more... i dont think they would mind that
If you want them to make videos more frequently, then they'll need more money. They need to pay people for all the work that goes into these- art, writing, research, voiceovers, etc. Their Patreon is right there, or you can donate to PBS.
@@SongbirdOfficial let me do what i think is good. please keep quiet. if u think they have so many problems then u donate
Derpion the Derpy so true!
This is pretty sad, but it's also natural selection. Only the resistant corals will survive
Well, technically it is natural selection, it's just that the selective pressure is too big because environmental changes are too drastic because they're happening too fast for the corals to adapt.
