How pollution is changing the ocean's chemistry | Triona McGrath 

I've been researching this regularly for about a year in academic databases. Everything she says is true.

Cortana in real life

Greed is destroying humanity and the environment

This was in my chemistry exam today, would have been great if I watched it before my exam.

We want to Stop Ocean Acidification to save our lives.

4:15 "Unless we can start slowing down our carbon dioxide emissions, we're expecting an increase in ocean acidity of 170% by the end of this century. ... This is within our children's lifetime." ONE HUNDRED SEVENTY PER CENT!

I bloody love an Irish accent.

This is the real problem with our planet. More people need to bring this into the mainstream

I could listen to her all day, love her accent

Interesting topic 👍☺️

If you evaporate seawater, does the CO2 go back into the atmosphere, or is it left behind as part of a different chemical?

Isn't the melting of ice sheets dilluting the acidification, maybe even overcompensating it, also bringing coralls to deeper i.e. cooler water?

Thankzz very helpful

Top most news of chemistry...hatsoff

We should try our best to protect our Earth!

awesome

Remember folks, "Never doubt that a small group of thoughtful, committed citizens can change the world; indeed, it's the only thing that ever has." Margaret Mead

As much as we discuss energy and trash reduction by changing our own personal life habits, ultimately that is a very ineficiente way to try and tackle the problems of climate change and subsequent ocean acidification, a better aproach is to openly support organizations, politicians and policies that seek to tackle the issue directly. There are many that do. That is not to say that a change in lifestyle is not welcome nor that it wouldn't help, is just that is simply not enough. Please, if you care for these issues contact your representative, donate, lobby, organize public demonstrations, this is how you do as much as can.

i know we have the resources to end world poverty... i do believe it is in the best interest of everyone to help. i know we can create more jobs with greater impact to the world for everyone. it is very straight forward and simple. the only issues we face a s a human species we can face together and end them completely. we have the technology and great minds. lets change this world.

Her honesty worries me.

If you care about climate change, then you should check out a video called "LFTR in 5 minutes". If you're feeling pessimistic about the future of the earth then I think this will give you hope.

So grateful for the 2x speed feature

I love how I keep seeing videos on pollution, overpopulation, habitat loss, deforestation, and a whole bunch of other stuff that humans have a negative impact on. BUT, no one does anything about it. I know there are small group of people who fight against this stuff, but in the end, no one really cares, they might say they do, but do u not use ur phone a lot? Do u not use electricity? Do u not drive a car? We humans are just going to end up killing our own planet, and ultimately our own species, along with many other species. No point in rambling about this stuff when no one in that entire audience is going to do anything to bring positive change. EDIT: A lot of you have been saying that we aren't told what we should do in order to prevent this. But we are! Students are taught about this stuff in school, and back when I was in tenth grade, I remember there was a unit on Climate Change in our science text book. So yes, we are definitely taught how to prevent this, and even if we're not, most of it is common sense, turn off the lights, try to carpool, etc., but only a small portion of people actually do that stuff. One source of the problem is our leaders, for example, in Brazil, the Amazon Rainforest is being exterminated, but there's no strict laws preventing deforestation. Similarly, in China, so many animal species have gone extinct there, yet there are no strict laws preventing poaching, etc.. If the leaders actually made some strict laws and enforced them, then I'm sure these problems would decline. I'm not even going to use a Donald Trump example only because Donald Trump is actually retarded. Lastly, we are the biggest source of the problem. The only people that can control a leader are the citizens. There's not enough programs, fundraisers, etc. that contradict poaching, deforestation, etc., so of course the leaders aren't going to enforce any laws regarding these issues.

My biggest issue with talks of this nature, is they leave me feeling completely helpless in how I can actually affect change ??? plus predictions without certainty just compound the confusion & apathy. I feel like a "drop in the ocean" (pardon the pun).

how a normal average worker can help in his daily activities to stop poluting his enviroment; reduce and divide the plastic in natural substances , do not buy new furnature but buy old ones so no new trees need to be cut down ,do not buy plastic that disolve into water , cause they really don't disolve they get smaller but the whales are eating this and all the other life inthe oceans, now you might not think this but this is very important, BLESS AND SAY THX TO ALL THE ELEMENTALS OF AIR ?EARTH? WATER? FIRE AND ETHER., you might think does nothing but its really not true, your thoughts are energy and when you give love and apreciation towards nature and all that is involved it strenghtens!!Do this everyday !!! bless each water you drink and each food you eat.study nature !!!visualize earth being very beautifull and filled with trees and in perfect harmony each day for at least 17 minutes:)love to all that is.

There was only one reason I clicked on this video... ay boys? ;D You know what i'm talking about ey? Ey? the title had the word Chemistry!!!!

I'm more concerned about the sea animals 🐳🐋🐟🐠🐡🐙🦀🐬than humans 👺 and whatever it will have on them

Everyone recycle and reuse as much as possible! We need to eliminate plastic bags, bottles, cutlery and straws!!! Use cloth grocery bags, you can buy paper straws off eBay and amazon! Use glass bottles as to go cups for beverages, and use chop sticks or wood cutlery! We have options and we have the power as individuals to make a massive difference! Also check out and donate to 4Ocean they are cleaning our beaches and oceans! I’ve already donated and plan on donating again! Please help the wildlife desperately needs our help and as adults we are responsible to leave this planet in a good state for future generations!!! We cannot let the wildlife die!!!

thank you for helping the earth bless you

Too many people just don't care; question is, how do we change that?

Epic video tho

What's the worst mistake you ever made, throwing something away? Was that the worst day of your life? Was your life over?

Rick Grimes says "Coral". Triona McGrath says "Carl".

How can a 9 minute vudeo already have two dislikes, when it was posted 5 minutes ago?

She is right. I will try to decrease carbon dioxide gassing. Let's do it together.

On top 🐸

can we hope for a sparkling ocean by 2050?... we're so fucked 😭

I know a guy named Carl. He's got a pretty cool shell.

Ocean is deep...they measure the surface.

Ocean acidification poses a grave threat to marine ecosystems worldwide. As carbon dioxide levels rise in the atmosphere, oceans absorb a significant portion, leading to a decrease in pH levels. This acidic environment hinders the ability of marine organisms such as corals, shellfish, and plankton to build and maintain their calcium carbonate structures, essential for their survival. Consequently, coral reefs degrade, shellfish struggle to form shells, and plankton populations decline, disrupting entire marine food webs. Preventing ocean acidification is crucial not only for safeguarding marine biodiversity but also for preserving the countless benefits oceans provide, from food security to climate regulation. Efforts to mitigate carbon emissions and reduce ocean acidification are imperative to protect the health and resilience of our oceans for current and future generations.

Just another reason to support the development of renewable, nuclear and geothermal energy.

It's a theory that long ago this is what happened to mars and will repeat here on our planet.

The principal problem of the acidification in the sea is the people don´t want to listen this problems.

the world Will end for the human actions

Hopefully I die before king-crab costs $1000 per pound.

does she talk about the trash contanants? and how no one wants to clean them up because "we didnt do it"?

And yet, 90% of the Ocean's remain undiscovered.

cortana?!

Dont get me wrong, I am ok with the ambiental matter but all these people who wants to preventing it are doing it wrong. You have to look and make people concern about the economics consecuenses of climate change and ocean acidification. When the consecuenses of climate change hit the powerfull CEO wallet I bet there will be a comitment to take action in less a year

Why does she have canadian accent with a tiny hint of irish

Fukishima!

Tablespoon professor financial plain vast lead endure.

They should really stop chem trailing then.

Putin will react the same way he did with greta now ?

Ultimately we need to reduce the human population without reducing its research efficiency. At our current level of technology selective procreation is the only means of achieving this. Selective procreation will never happen in democratically governed nations because it is against the short term interests of the majority. Thus we need nations to switch to some form of autocratic government. However, achieving this peacefully and in a nondestructive manner is exceedingly unlikely. TLDR; it doesn't look good.

If you want solutions let's first talk about genetic engineering: We could create new variants of endangered organisms that are more tolerant to acidification while the people of the states are kicking Trump and other Republicans out of the government in next elections. All the rest of us should also prepare to vote green. Renewable energy with energy storage + electric cars are way to go if you dare not use nuclear. Ocean fertilization is one serious subject to be considered and forestation is always good. Advanced algae ocean farming would be best way to satisfy rising demand for food. The last line of defense is industrial level carbon removal(if possible) and space based shades for the poles(if those can be relatively cheaply constructed from the moons materials).

Well all that is running out over greed & stupidity. They just don't care.

The last time I was this early. Global Warming wasn't a issue

Humans have shown little interest in changing. Our planet is doomed.

why she is naked ?

She's putting all the expecting data... Future reality could be far more worse.

Its too late for the human race, this world is too far gone. Perhaps in a parallel universe we are doing a bit better.

stupid youtubers get over a million views but this has only 57K??? Shows how much people care about our earth...

Go vegan and yes people can just do it. Yes it easy. Go try the beyond burger. It's in the meat isle. All vegan.

Soon all things on earth will change. Psalm 37:9-11,29; Revelation 11:18. Want assurance? See jw.org

don't speek of polutin, f propaganda, this has been done in 1993!!! for f sake :James Dyson shows cyclonic diesel exhaust filter to Blue Peter in 1993, and your parents denied cose of f comodity ffff comodity!!!!!!

Hawaii? Seriously? You open your talk by talking about Hawaii? You should be collecting data from the coasts of Europe, America or Asia. Not Hawaii! People won't relate. Expecially those who don't want to relate. Even if it applies to the whole world. People's little minds will only hear that it is in Hawaii, and they won't care as much or at all. Come on! You should be smarter than this! What a waste of an important message... :( (It still gets my like, btw)

And again human trying to be smarter than Mother Nature.....I see some business behind....

BUT Water (H2O) has a ph value of 7.14. And being acidic would make the value LESS than 7... But your graph shows the low point of 8.03, so it is not technically acidic. And I don't know so I am asking - What difference would a 0.35 difference in Ph level have?

Them legs though!

We are not going to solve these issues. I say live your lives well and take what you can from the environment, until our inevitable extinction.

That voice...

I've never got to go to an ocean. I'm 28 years old now. I have always wanted to see an ocean... Except now I really don't care. It's very hard to care about the ocean and it's lifeforms when you grew up landlocked and never got to travel until you're an adult... All i feel for the ocean is bitterness. Oceanic pollution has literally zero bearing on *my* life. And you fish-heads will receive no help or sympathy from me.

I thought she was going to talk about real pollution, not a naturally occurring trace gas that is essential for MOST life on this planet. Also, I don't know where she is pulling her percentages from, but they have no basis in reality. "26% increase in ocean acidity"? This doesn't make any sense. What is the baseline? What is the starting pH and ending pH? What does this "26%" correspond to? We the actual need data to get a proper context. This is how fearmongering from a political activist disguises itself as science. SOURCE: 04:00

first :D

I pleasure moaned a little when I heard her accent

looks like garbage political science but i could be wrong.
