Instead of wasting money on war and nuclear weapons, Developed countries should invest more money on protect nature and reduce the threat of global warming.
While war business is more profitable than green projects, it will always have an advantage over global environmental problems. The only thing the capitalist system understands is how to produce more and more goods, it is an endless procedure.

Excellent message. I wonder if dictators like Russian Tsar Vlade the Warmonger would follow your excellent advice.

Co2 can be converted into Graphene. We have the solution.
It's sad that nothing will be done until it starts to heavily affect people who live inland. I genuinely don't think humans will ever care tho.. 😔
something's being done, slowly were getting there, we just need to raise more awareness
It is too late, even if we stopped all emissions tomorrow it has been scientifically proven that things will just get worse. The time to do it was in the 80s
@@sew_gal7340 HAHAHAHAHA THEY SAID 'WERE TOO LATE" BECAUSE THEY PREFER TO WASTE TIME CRYING ABOUT STUFF THAT DOESNT MATTER TO THEM INSTEAD OF ACTUALLY GETTING THINGS DONE HAHAHAH
Its not humans that will never care... its the capitalists who are the problem. They are psychotic and evil.
Only when it becomes profitable for billionaires and billionaire corporations will they actually move to stop producing these poisons and waste products
I appreciate the work that went into producing this. It's absolutely viral to drive the urgency of this problem to the public.
Co2 can be converted into Graphene. We have the solution.
The public knows, so do the governments .. the problem is, the governments don't care because they're owned by the very people doing all the damage and have no problem leaving their grand kids' a world in ruin where their families will die so long as it makes them just a bit richer today.
you should have the urgency of this problem driven into you every morning instead of breakfast.
and then you will sing a totally opposite song buddy.

We need more of these videos. Insight into a world a lot of us don't know.
Climate change is very informative. The world is unaware that the acids and carbon in the ocean destroy aquatic life, which has an impact on the food chain. We need to hear more stories like this. Bravo for this video's superb reporting.
The lower the pH value, the higher the acidity of a liquid. Solutions with low pH are acidic and solutions with high pH are basic (also known as alkaline). Prior to the Industrial Revolution, average ocean pH was about 8.2. Today, average ocean pH is about 8.1.
pH is a measure of how acidic/basic water is. The range goes from 0 - 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.
Based by this science and a wee bit of simple mathematics (Now, I know most of you in the USA will fail to understand this simple mathematical formula as your school test scores reveal), shows that at the current rate, oceans will become acidic by the year 3400. Well past that date if indeed, the polar ice melts.
Ocean acidification turns out to be a very serious concern and the subscriber is highlighting the need of the time in this video which is appreciable
Wow, we truly have messed up big time
Its not 'we' that have messed up... its the capitalists who are the problem. They are psychotic and evil.
The awareness created in these are amazing things we can do.
I have never heard this before! How come? This should be news stories all over the world.
Start reading National Geographic Magazine.
I've known about it for years now. Gotta be plugged in, looking around. Watching educational tv, listening to educational radio. Looking at news sources around the world. Most would rather ignore anything serious.
Because it's not true. I suggest you check out a lecture by Dr Patrick Moore, he's a PhD in ecology and a founding member of Greenpeace. He's been trying to debunk this fear-mongering for years.
@@elmartillo7931 Founding member of Greenpeace? Sure.... 🙄🙄
@@christopheespic Yes until he started speaking out against them, and it's interesting how it's so easy to delete things when they're made electronic
We need more videos like this it’s for people awareness.Really informative videos
Ignorance is Bliss - surely you've noticed.
We need strong journalistic entities like you reporting on issues like this with the seriousness and urgency that you've reported here. We need to nourish collective awareness so that everyday people can know and act against the existential threat we and all life on earth are facing. The time to act is now.
Such a fascinating topic more people should be aware of!!
Everybody has known about this for decades.
Very sad to see the beauty of the sea slowly dying off.
We need to take care of this planet so future generations can enjoy the wonder and awe of the sea!
This video was amazing. I learned so much from watching your video would definitely recommend this. Great work
Thank you London's Natural History Museum.
more stories like this please.... the world lacks knowledge that the acids and carbon in the ocean kills living being inside the water, which will then have repercussion to food chain... well done for this clip... excellent reporting.
@@brokencountry283 that is SO idiotic and about a 6 grade level of science...if you never paid attention in class fool. plants need MORE than carbon to live, and animals aren't PLANTS child. so hey, if you want an earth just for plants and a few animal species left...that nihilistic vision is on you. a planet to hot for humanities food crops and it's livestock. where water is scarce and arable land even scarcer.
lastly to move the education scale up to uni, there are different types of photosynthesis which you simplistically equated to needing carbon to live. oh WOW, here's a surprise, being a CHEMICAL reaction, not MAGIC, it has limitations ONE of which is HEAT which when it increases it disrupts photosynthesis shutting it down completely or shutting down the carbon process. not all photosynthesis is equal child, go back to school.
@Broken Country says how much knowledge you have in your head...read or go back to grade 1....Ocean acidification is a consequence of increasing carbon dioxide (CO2) emissions, a greenhouse gas driving climate change. The ocean absorbs around one third of all human induced CO2, causing a change in seawater chemistry called ocean acidification. It presents a serious threat to marine life, ecosystem health and people whose livelihoods depend on the ocean.
Literally every country in the world: I'll ignore that
Politicians renege on promises. Entrepreneurs promise new 'green' tech - though it'll end up polluting the seas (and the rich are just after making more money). I'm giving away a FREE novel on TH-cam, Zen And The Art Of Saving Life On Earth. If enough people read it... 🤔
Humans are bad at making short term sacrifices for long term benefits. Look at obesity rates.
@@neillynch_ecocidologist How do I give you money?
Fun fact. All rain, especially during thunderstorms, is acid rain. Sure, some CO2 might contribute, but it's mostly nitrous and nitric acid. Lightning fixes nitrogen oxides naturally and these when dissolved in water make acid.
not a fun fact, and one everyone knows.
And now I am wondering if nitric acid is stronger than carbonic acid. It seems to me that HNO3 dissolves CaCO3 better that H2CO3.
Another question: why no one says that the atmospheric CO2 might be increasing due to huge amounts of CO2 released by corals' and bivalves' shells dissolution (pure CaCO3 that releases CO2 in this process) which occurs due to acidification caused by various reasons? May be human impact on CO2 increase in the atmosphere is not as great as we believe? After all an expert from Hawaian CO2 capture project says: there are 150 times more CO2 in the ocean than in the atmosphere. So whatever ocean does is way stronger than what we do with all our industry.
Thank You for the information.

Very informative and revealing. The Economist never fails to deliver well supported research with verifiable information.
Yes very informative except for one thing - does not discuss the most important issue facing humanity, overpopulation. Typically men can put down their subjects, but because women dominate voting, this will never be discussed. Instead grannies will march us towards the cliff.

frustrating and sad
It sounds like we have no idea for sure why exactly sea creatures are disappearing due to a lack of research. It's hard, as a land dwelling human, to care about what happens under the ocean but I feel like we need to put a little more importance on studying what covers three quarters of our planet, since our survival depends on being part of a functional ecosystem. Thank you to the people responsible for this report, and to all those studying our oceans.
The answer is in the title even, acidification. What kinda bot are you?
@@enternalinferno the human kind, i guess. Maybe one with a critical mind, that might be what's confusing you. So you're stating that the video itself lied when they said acidification 'could be one of the causes of this decline.'? You think they know for sure and they just aren't telling us that? I looked it up for you, the quote is at 10:57 . feel free to watch it for yourself.
@@enternalinferno PH of water is within normal ranges. So what is the evidence of acidification vs natural variance? Normal ph of ocean water ranges between 7.8 and 8.2. Current ph at 8.1. So ph is on the high side of the normal range towards less acidic.
@@volkerengels5298 Understood. Thank you. I will trust the numbers you are giving.
However, at 8.1 it is still at the high end of what is considered the normal range for seawater. And considerably above the ph of pure H2O at 7.0. So any claim of acidity is overstated as the standard would call drinking water highly acidic and a greater threat.
Seeing as carbonic acid, the main threat as I understand it, basically breaks down at 25 C to water and CO2. Then, CO2 is respirated and eliminated from oceans rather than enhanced at elevated temperatures, I fail to see the threat.
Current mollusks, coral and crustaceans existed and in fact developed at much higher atmospheric CO2 (1000-2000 ppm by most estimates) as much as 60 MYA without injury of acidification. And many studies show ability adapt to dramatic change very few generations. Even the worst predictions I read show any injury to be a few species specific rather than general extinction events.
@@jameshughes3014 Being ignorant and just saying 'we don't know for sure' isn't having a critical mind. Honestly, nothing is 100% certain when it comes to ecological changes because everyhthing is entangled. But if you haven't got an actual alternative suggestion then your so-called critical thinking is just hot air.
Great video. I'd never heard of it before. I'm amazed how this isn't more common widespread knowledge.
Know what you mean, I amazed it's not more common knowledge, that the average temperature during the Medieval Warming Period was 1c hotter than the average since victorian times, or that the average temperature during the Roman Warming Period was 2c hotter. Must be because if disproves all the climate alarmist BS, and shows it as the tax grab con, it's always been
Thankyou for giving insight into this matter.
Solid na Documentary na naman
Cute that "The Economist" figured out that economists killed the Earth.
🤣
THE MILITARY INDUSTRIAL COMPLEX. THE WEST.
let's not beat around the bush they literally scorch the earth with fire, explosions, nuclear bombs, set light to oil fields blow up gas pipelines displace millions in countries of nomadic herdsman. The U.S government and its allies need to be held to account for the destruction of the environment and millions of suffering lives. they have the audacity to host climate summits and fly there in private jets and entourage. A country built on the blood of Indians. Stop supporting The mainstream media if they won't hold them to account and would rather guilty trip the new generations for their emissions.
Economist usually avoids biophysical reality like the plague as it mentions the unstated costs of the industrial system it thoughtlessly promotes.
✨🌎🇺🇸 Excellent Field Environment Reporting 👍
In many cases, I would be of the opinion that technology can be used to solve a problem. But when it comes to capturing the CO2 emissions that are already out there, I really think all these different ideas/projects going on now is just not right. They are not a reasonable solution, we cannot have millions of units maintained to deal with just what we had already. This is really, like inventing the wheel when it already exist! Instead, helping nature to recover and to grow more to capture this for us is absolutely the way to go.
The only way to end it quickly is to allow it to happen and maybe half hte population will die off and hte earth can heal again
@@sew_gal7340 When you say half the population, it's surely referring to humans and most likely it's the poorest that will die, not to mention all the other species that will die and eco systems that will get destroyed. Yes, humans may as well die off, but we are not alone.
If we wanted to clean up our c02 emissions to date (not future emissions) using the tech at 13:30 it would take something like 27 trillion containers 27 years to clean up and would cost 11 QUADRILLION dollars... and if you put the shipping containers end to end, they would wrap around the earth nearly 3.5 million times! The co2 cost of building and running all these carbon capture devices not included.. its a joke.. please tell me my maths are wrong... But didn't he just say it would capture 37 tonnes a year.. and cost $425 per tonne.. $16k per year! also this is only co2 we have put out so far.. we would need to scale this up even more for all the future co2 emissions which are still rising!
@@DuncanAtkinson yeah, I will not do the math, but I agree. it's like a gimmick, no value just an idea (a bad one). one of the dangers nowadays is that there are many not viable options still being pursued because people see opportunity to make money.
@@wowJhil or worse funded by the oil industry as an excuse to continue to drill for more oil
On one part I am concerned on how ocean carbon capture can be problematic in the same sense as atmospheric carbon capture. But at the same time, it seems to be something that can buy vulnerable coral and reef populations enough time to live through climate change (so that we don't permanently lose them). I can imagine implementing such technologies, on say, the Great Barrier Reef. Hopefully this promising technology comes to fruition and hopefully it doesn't introduce more problems than solutions.
The ocean is protecting the atmosphere from warming and excessive carbon dioxide. The warming is also preventing oxygen from dissolving into the water. Unfortunately, it's also killing ocean life, and it will take a very long time for it to recover. Studied this while getting a degree in environmental engineering.
Well put together documentary
Tx for this excellent video very informative.
There will never be a "silver bullet" for ecological & climate restoration, but rather a variety of strategies & techniques will need to be applied that best suits different contexts.
This is why global cooperation is so important - countries need to learn from each other then implement the techniques or strategies best suited for their local ecology / ecologies (most countries have a range of ecological systems within their national border).
Human sectors also need to work together to protect & care for the ecological sytems, processes & services ALL human systems FULLY depend on - govs, business, NGOs, civil society, groups & residents etc.
Our oceans are, by far, the most important carbon sink that our climate system depends on to remove excess carbon from the atmosphere so maintaining ocean health is critical.
Several techniques have been suggested to reduce ocean acidification such as ocean fertilisation & silicate weathering. 3D printed or mesh coral reef bases onto which corals can attach is also available.
But nature is still the best solution because ecological services are provided FREE OF CHARGE and have been developed & perfected by nature over billions of years.
Great documentary.
Oceanic acidification happens first. This happened in the past, during the Paleocene-Eocene Thermal Maximum. The world warmed by 5-8°C, there were rainforests in North America. The amount of carbon dioxide in the atmosphere sky rocketed, the oceans absorb carbon dioxide and the ocean suffers first. Then once the ocean can’t take anymore, the air becomes more concentrated with carbon dioxide and the heat on land sky rockets as well.
I love it when it's hot outside.
Animals and fish love it too. As it gets warmer expect to see more-and-more of them just lazing about sunbathing. Don't disturb their rest though! You wouldn't appreciate it and neither do they.
@@EmeraldView Heat kills about a 100 times more people, than cold.
Animals and fish don't love it. They die of it massively.
Guess you are not the standard of everything.
@@gardenjoy5223 I was being facetious. 😋
Yes this will be devastating for wildlife.
@@EmeraldView Aha. Thought it was your age :)
With too little oxygen in the water, because it is too warm, we already had die offs in the millions! Horrid.
@@gardenjoy5223 tell this to those who survives in harsh winters. Both heat and frost crop thousands of lives every year globally.
I’d like to see other potential contributors to falling ph levels. I have a pool, and one option to lower my ph is to add fresh water. I think we need to add the melting ice caps to the equation. Also, in the San Francisco Bay Area, we push so much treated water into the bay that the salinity (and ph) has dropped in the bay.
Problem is that there's still a continuous injection of carbon dioxide worldwide to the oceans. The melting of ice caps may slow that rate for some decades, but after that, assuming we haven't sill cut down to zero our human emissions, the ocean will keep on become more acidic once again.

Main causes of C02 emissions:
Burning fossil fuels:
The largest source of CO2 emissions is the burning of fossil fuels such as coal, oil, and natural gas for energy. This includes emissions from electricity generation, transportation, and industrial processes.
Land-use changes:
Deforestation and land-use changes, such as conversion of forests to agricultural land, can release large amounts of carbon dioxide into the atmosphere.
Agriculture:
Agriculture, particularly livestock farming, is a significant source of greenhouse gas emissions, primarily methane and nitrous oxide.
Industrial processes:
The production of cement, steel, and other industrial products can release large amounts of CO2 emissions.
Residential and commercial buildings:
Energy use in buildings for heating, cooling, and electricity can also contribute to CO2 emissions.
We know the cause, we have some solutions. The only things that are preventing us from making changes are the people, governments and companies that are currently profiting from our current way of life, its not sustainable. Words are getting us nowhere... Actions speak louder than words.
There are 2 billion people in the World today whose only source of energy is burning wood. Keep them in mind when you blaim combustible energy sources. Humans need energy to exist, so all combustibles will be in active use for a very long time.
Thank You For This awesome Documentary❤❤❤. (Please Save The Ocean🙏🙏🙏) (Please Save The Earth🙏🙏🙏).
On top of the acidification is the sheer volume of debris and chemicals being washed into the ocean after every major weather event. Petroleum products, garbage, soot and topsoil, pesticides, debris from damaged and destroyed homes....
Most of it causes no real harm to the ocean. It had happened before the human era too. May be there is some damage for some animals, but it only means a feast for other animals.
@@user-ed5zl2cw2h No, in fact quite the opposite.
@@deepashtray5605 in short term there is damage of course, but long term other factors have much more weight. (I mean evolution time frames where a whole species is considered, not an individual animal).
@@user-ed5zl2cw2h Even without factoring in storm debris there are a number of "whole species" being directly threatened right now by all the garbage, debris and chemical waste we are dumping in the oceans, including species of sea turtles, whales and dolphins, and many pelagic bird species such as the Laysan albatross.
@@deepashtray5605 I believe it's definitely necessary to manage our waste and environmental impact better. But I am afraid it's not possible to completely eliminate the damage we bring to other species. Humans are invasive species, very adaptive and currently growing in number. Unfortunately we by design not only adapt ourselves but adapt the environment in order to survive and grow the population. As animals we won't limit ourselves in order for other animals to thrive. It takes a lot of education and wealth to change priorities in a particular person, so they would start considering anything beyond their survival and procreation. Most of human population is not that wealthy and educated. So unfortunafely the trash will keep coming into the oceans. Hopefully in smaller amounts. (FYI: it's still allowed by international law to throw away food waste from ships into the ocean, only internal seas like Black sea are protected. Yet still sailors throw away not only food waste but also beer cans and other non-food waste even in the Black sea.)
How does melting ice caps affect the ocean acidification?
The salinity declines and the sweeter water acidifies even faster.

What can be done? Nothing, deal with the fact that the Earth has always been changing and will continue to.
Just remembering haven’t heard about acid rain for a long time
Right. Because nations took action and outlawed certain chemicals.
Hmmm
Polar caps contain fresh water,
Maybe they are supposed to be melting.
I like tech but huge sea grass and kelp farms sound sustainable and could produce more jobs, products and sea life to hide from predators.

Great topic!!
Yes I think we should all pay as much as we can to the various privately owned companies that collect carbon taxes. They need it more than we do .
The Economist does not have the interests of the environment in mind.
Dangerous drivel. As regards ocean acidification, it is estimated that the ocean’s global mean surface pH may have declined (i.e., become less alkaline and thus more “acidic”) by -0.07 to -0.08 in the last 200 years - from pH8.12 during pre-industrial times to 8.04 to 8.05 today (Wei et al, 2015). N.B. The decline in pH occurred before 1930.
However, and very importantly when you look the data after CO2 emissions began rising precipitously in the 1930s, the oceans have become less “acidic”!!!
By way of comparison, from one season to the next, or over the course of less than 6 months, pH levels naturally change by ±0.15 pH units, or twice the overall rate of the last 200 years. On a per-decade scale, the changes are even more pronounced. Oceanic pH values naturally fluctuate up and down by up to 0.6 U within a span of a decade, with an overall range between 7.66 and 8.40. This is decadal rate of pH change is larger than the overall 200-year span (0.07-0.08) by a factor of 8.
Thank you!!! We need some sanity here.
Read about all of the cycles of the Earth, we have had this cycle twice in the time the Earth had water.
I'm puzzled as to the inclusion of Heimdal in the video. Or, perhaps with a little more generosity and less skepticism, why Climeworks (direct air carbon capture) was not. Without further information it's hard to envision either as more than tech-saviourist, wishful thinking.
Up to that point, I thought the video was well done.
We should farm native plants and animals we should eat the invasive animals to reduce destruction of wild life and reduce hunger a bit more.
The only answer currently is nuclear fission, unfortunately the nuclear industry is highly reluctant to update there reactors to a safer non-uranium and water design like Thorium Molten Salt Reactor. So if you're planning on fish&chips in the distant future you will be paying dearly for it, from a aquaponics Farm that grows tilapia a reasonable cod substitute. The farm will most likely be powered by a thorium reactor purchased from China.
I worked in the CO2 laboratory in college at the PRRC at I can tell you CO2 is highly reactive.
Great job, humanity. What's next?
*capitalists. i didn’t cause this…
Extinction
Bicarbonate might be injected in great quantities to buffer ocean acidity -- it is already applied in plankton farms. However, somebody need to pay for it...
Let's grow lots and lots of kelp, and put the computer data farms underwater (either the Economist or Bloomberg have done a video on that), and change our proteins from cows and seafood to insects. That would help! Oh, and yeah. Back to bicycles.
Are you sure you want to heat the ocean with data farms? :)
Nobody ever talks about breading " the world is over populated it simply can't sustain
"If the world were to end all meat and dairy production and transition to a plant-based food system over the next 15 years, it would prevent enough greenhouse gas emissions to effectively cancel out emissions from all other economic sectors for the next 30 to 50 years.
That’s according to new research published today in the journal PLOS Climate. The paper’s authors say such a shift would “substantially alter the trajectory of global warming,” as animal agriculture is estimated to account for around 15 percent of global greenhouse gas emissions."-Vox (Title etc, follows-
"This is how much meat and dairy hurt the climate"
*That would give us at least 30 years to transition from fossil fuels to renewables!*

design an experiment with 11 flat bottomed flasks, each containing air with, 0.00%, 0.01%, 0.02%, 0.03%, 0.04%, 0.05%, 0.06%, 0.07%, 0.08%, 0.09%, 0.10% of carbon dioxide and a thermometer. keep them equidistant from a heat source and monitor their temperatures over a 24 hour period, to confirm how co2 affects atmospheric temperatures.
The surfers are swimming in acid. This is horrible!
Wow, wow, wow. Breathe! The ocean is still slightly alcaline. It will never be any close to what you consider being an acid. Your skin (pH 5.5) is way more acetic than the ocean.
It's going to get worse when we start digging up resources from the ocean.
What's the worst situation, for the future children will find a horrible world 😢. In my case, I'm reusing plastics as much as I can. And I take care my garden. It's not too much but at least is a small step
I don't understand some of the comments here, what do they have against combating climate change? and how is this topic even still debated, it is well established that we caused climate change and it should be stopped. Really bewilders me how there are still people not believing it exists.
It is NOT established that humans cause climate change. Since the last Glacial Maximum temperatures have fluctuated dramatically with no human intervention. 6000 years ago the Arctic Ocean was ice-free in Summer.
@@romanpolanski4928 What is your source for that? Knies et al. (2014) put the Artic Ice cap being in place from around 2.6mya.
@@romanpolanski4928 yeah its true but were warming the planet faster than it can adapt .-.
@@XlendneryGD Not so. During the Dryas and Younger Dryas Episodes at the end of the last Glacial Maximum the temperature changed by 5 deg C in only a century.
@@romanpolanski4928 well yeah but the current heating is because of us unlike the cooling your telling me. This mean we have the possibility to control if it we wanted
I worked at a lime company. Couldn’t crushed lime stone be spread in the oceans? To raise the PH?
I think what youre thinking of is to make the pH increase in value. So like 8.05 to 8.15. That actually makes it more alkaline and less acidic.
Now with lime stone, I'm not sure if it would do that as isn't lime stone acidic naturally?
@@asiancuteness8517 that’s what I meant
@@asiancuteness8517 mo, it’s very alkaline
Folks all the animals mentioned in the video consist of limestone, or better to say limestone consists of these animals. Dumping 0.1% of the limestone that already covers ocean floor (above limestone stability critical depth) is not going to change the ocean's pH in any way.
Wow……. The whole body of the ocean could become highly acidic. That is so depressing
woods hole oceanographic institute studied coral in a very low ph environment near underwater co2 vents and found , much to their surprise ( and disappointment) that the coral was thriving .
they also found that coral in the ocean reacted much differently than coral in the laboratory
Lord...whole Earth is in danger.
