I would want ted to make an video on world population problem and do some research and come up with numbers and solutions for developing countries . Also I grew thinking this alot ... Like what if only 2 billion people lived on earth and stuff. It's an idea I don't really see people talking about and having concerns .. I would like you to uptake something from here ..
there were moments when the music felt like a water clock ticking, I was picturing in my mind a hourglass that drips water droplets instead of a sand stream, ticking an anxious countdown. it was counting the time we got left on this green planet, and that's gonna run out eventually if we don't stop wasting our precious fresh water
Thank you so much for your lovely comments about the music I did. Feeling lucky and very happy to work with Kozmonot Animation Studio and TED-Ed again.
@@animegirl7364 Thank you but unfortunately there is no video with just the music. Although it is my composition, I did it on demand just for this video so they come together as a package. Sorry...
But will you guys expand on how industries like the golfing and other sport industries spend tons of gallons of drinking water on lawns. How reservoir are being used in Nevada for Golf Courses rather than sustaining the public. Agriculture is part of our lives, while wasteful leisures arent, especially if those leisures are at the expense of peoples literal survival. I adore these videos about saving the earth, but this deflects from greater issues. You are masters of non-partisan debates and conversations and can really do address outliers that effect so much more of our lives, that are right under our noses.
@@chieuleyang6768 you ever been to a golf course? Its real grass bro and grass needs hella water if its gonna be green year round. Especially in a desert like Nevada
This is basically where all the water in Dubai comes from, distilled seawater. The process is expensive, has an environmental impact and uses a lot of energy.
This video is very well done. One note to make is humans, while some do things that are very reckless to our environment, there are others who are doing amazing good for our planet. Humans are smart and we will find ways to go around these crisis’ that our predecessors left us with. That’s why it’s so important to educate ourselves and our children. As well as support new ideas and companies who are trying to produce cleaner, more efficient energy and farming techniques. It may be a little scary to look at the future, but with each generation we are becoming more informed of our footprint on the earth. And with each little decision we make to help the environment the more our youth will see that and grow up to hopefully make the big changes for our planet. Just wanted to give a little positivity to those who might be discouraged.
Positivity is definitely needed. But the biggest issue in regard to this, is the speed in which we develop these new solutions, and the reforming of the existing ones. Economic growth is still the highest priority to lawmakers and industries, due to globalized capitalism. If we don't change this priority, globally, it will result in the demise of civilization as we know it.
Bramble you can still be positive but be grounded in reality. I’m not saying to just shut your eyes and pretend everything will work out. But just to look for and support people who are trying to do good. Or if you find yourself able to make a change, make that change! You don’t need be a pessimist to get change and be more in tuned with reality. In fact you will rarely see a positive change if you’re looking at everything negatively. Just my two sense. ❤️
sad sad thing is that US government is not believing in climate change, and pollution continues to increase global warming which is melting glaciers and flooding planet and making little islands disappear , now 8 metres of glaciers ice has melted it keeps melting , i want to stop it WE want to stop it but if we don’t like Stephen Hawking said that in 600 years our planet earth will be burning hot if we don’t do anything to stop it , it makes me sad , im only 12 year old that is trying to change something.......
I’m actually incredibly shocked by this. Not only the amount of water we go through daily but also the urgency to reduce it. Ithink I’ll start taking shorter showers now...
Start by reducing meat consumption, more specifically red meat. Not saying to give up meat entirely, but try to replace one normal meal with a vegan meal each week. Raising live stock requires large amounts of water. Not saying agriculture doesn’t use large amounts of water either, but you have to factor in the amount of water need to grow feed for live stock too.
@@Spacemonkeymojo Yeah I know. I was equally as shocked. I saw many commercials on tv telling us not to waste water and turning the tap off while brushing, and i thought the same thing "What kind of idiotic moron brushes their teeth with the tap on?"
Please discuss the importance of reducing water pollution as well. It's not just a question of how much freshwater is available but the quality and health of the freshwater source/supply. Thank you!
I suggest that people buy buckets and fill them up with water and use those to take a bath instead of a long shower. That's what we do here in the Philippines, it saves so much more water!
The corrections of various types required for atleast 50 years or till the underground water table is risen good. Use alternate good quality temporary materials. Ban on all concrete constructions like multistorey, Underground tunneling for metro projects. Use of crops requiring least water i.e ban on rice plantations till safe. The world has to control on their taste buds till the right time. Harvest water drop by drop by placing winter fog nets. Harvest rain water by everybody. Dig out water storage tanks. It's now or never.
I've always been amazed at how beautiful clean clear water comes right out of the ground here in California. The rice farming industry here in Northern California uses a massive amount of water that evaporates on a massive scale.
One thing we need to do is move water from the ocean back inland to places we need it and if we can do that while generating clean energy we have a chance to mitigate climate change and still have a prosperous future. It is really, really hard but it is not impossible. The biggest idea I am trying to express is tunneling aqueducts from the coast, in this case the west coast of the USA inland to feed combination geothermal power and sea water desalination plants. The idea seems to be so big that no one has considered it possible but I believe it is not only possible but it is necessary. For over a century the fossil water contained in aquifers has been pumped out to feed agriculture, industry and municipal water needs. The natural water cycle cant refill fossil water deposits that were filled 10,000 years ago when the glaciers melted after the last ice age. Without refilling these aquifers there is not much of a future for the region of the United states. As a result ground levels in some areas of the San Joaquin Valley have subsided by more than 30 feet. Similar fossil water depletion is happening in other regions all around the world. TBM and tunneling technology has matured and further developments in the industry are poised to speed up the tunneling process and it's these tunnels that are the only way to move large volumes of water from the ocean inland. The water is moved inland to areas where it can be desalinated in geothermal plants producing clean water and power. In many cases the water will recharge surface reservoirs where it will be used first to make more hydro power before being released into rivers and canal systems. It's very important however to not stop tunneling at these first stops but to continue several legs until the water has traveled from the ocean under mountain ranges to interior states. Along the way water will flow down grade through tunnels and rise in geothermal loops to fill mountain top pumped hydro batteries several times before eventually recharging several major aquifers. What I am proposing is essentially reversing the flow of the Colorado River Compact. Bringing water from the coast of California first to mountaintop reservoirs then to the deserts of Nevada and Arizona and on to Utah, New Mexico, Colorado and Wyoming. This big idea looks past any individual city or states problems and looks at the whole and by using first principles identifies the actual problem and only solution. Thank you for your time, I would like the opportunity to explain in further detail and answer any questions
We can use the process distillation to separate salt from water and use the water that we distilled for drinking purpose and agricultural use , We can use fog catchers And Solar powered water filtration
You mentioned that the majority of our eater is used for agriculture, but neglected to mention that the VAST MAJORITY of that water goes to ANIMAL AGRICULTURE. Adopting a vegan diet is the most sustainable lifestyle choice. ❤❤🌱🌎
Hi, amazing video, but I have a couple of questions: I'd had liked to know the stats separately of agriculture and cattle raising, especially since you said going vegetarian reduces 1/3 of the water consumption, does that means cattle raising consumes the other 2/3. also, a great part of the agriculture products are destined to cattle raising itself, does the 1/3 agriculture water includes the products destined to them? or which is the proportion destined for human consumption in correlation to the cattle raising. thanks in advance if you get to read and answer this comment !!
Once water desalination plants become cheaper to build it will make water an infinite resource to use. We just need to figure out how to lower the cost.
And how to not polute the ocean with the brine that come from desalinated water. Besides, it's not a perfect technology because still it could harm the humans and the animals.
So proud of the fact that Ted-ed has the guts to explain that the main issue is by far, actually animal agriculture, which is an issue most organizations like Greenpeace aren't adressing. For anyone wanting to make a difference, I urge you to read "Cowspiracy".
This is going to be a long one. At first I thought freshwater shortage shouldn't exist because water doesn't vanish after we use it. But I realized that once we consume freshwater, it turns into sewage, which needs sewage treatment plants to be acceptable enough to return to the environment. While the treated water is technically freshwater, it can't be used because people wouldn't be comfortable with it. This freshwater gets mixed into rivers and ends up in the oceans, turning into saltwater. The only way for it to turn back into freshwater is through the water cycle, which we can't control and stays pretty much unchanged, or via desalination plants, which are extremely costly. So the reason we're having or will be having a water shortage is because we've found a very easy way to turn freshwater into saltwater but not the reverse. In other words, our freshwater consumption is increasing (because of increasing population and industrialization) but its supply is constant, or decreasing even, as glaciers and polar ice melt. This seems problematic but it can be easily fixed by increasing our freshwater supply. Even recycling sewage water would be a permanent solution because as our consumption increases, the amount of recycled water increases as well. It's a self-sustaining system. Or perhaps we'll find some other way to do it.
But we are already taking the water out of the river, and than put the cleaned water in the river. It's not like we magically lose water somewhere when it hits the sea
@GearsW You are correct but we always pump in water from the upstream of a river where it is the purest and then pump out the treated water to the downstream of it, where it is rarely reused. We could totally reuse that water but there would probably be huge public backlash over it. And while we don't lose the total water when it hits the sea, we do lose quite a bit of freshwater. Once it hits the sea, it mixes with the saltwater there and becomes saltwater itself, which is so costly to turn back into freshwater that it's much cheaper to just pump more water from our original river upstream. Hence our only source of freshwater is the river upstream. And the river does not have an infinite supply of water. We cannot pump more water of out it than flows through it, otherwise it will dry up. Hence the problem.
Sidhu Saab ❤️.... Naam padh k aagya notification ch... Proud PS - Sidhu sir, please study how much water every year we give to paddy in PUNJAB only and if we replace paddy with other crop how much water we can save.!
Wait, red meat? Isn't the meat which requires much more water than any vegetable? 80% of the agricultural water goes on feeding the livestock and growing plants for them...
Yes, I'm disappointed with the end of this video. A big reason animal products require so much water is because crops have to be grown to feed the livestock, when we could just be eating the crops ourselves. I don't know why ted would mention shelled nuts first and meat second.
@@Lucas43434 The creators probably thought people would disregard veganism for a sustainable future. Even if veganism is the best way to reduce our environmental footprint, Ted-ed understands the hate/backlash it would receive. That and they also might be biased so they can continue eating their meat because most plant based foods are significantly way more sustainable than any meat ever grown.
Sadly, suggest to someone [especially Americans] to stop eating meat and they immediately shut down or become incensed. I'm not from a professional psychology background (I only have an interest), but it seems to me to be a response of the discontinuity of presenting someone with an idea that makes sense but they simply do not want to accept: The bad feelings come from their Cognitive Bias - the ego being unable to consolidate these two competing ideas. I actually think very sly, subdued attempts like this video might be the best way to get to people.
@@alexp.7637 Mass starvation and drought are not my type either. I'm just saying we'd save 99% of the water we use in agriculture by switching to insect, plus we'd have a better nutrition. The only barrier separating us from an insect-based diet is immaturity.
Years ago, we got plenty of water to drink and for everyday use. Nowadays, we have to pay for it either buying bottled water or paying to water distributors. Clear water is also wasted by people in so many ways listing all of it would make this comment section like a thesis.
its so frustrating how inefficient we humans are, 1. when we go up stairs we have to work hard, but on the way down we have to work to not go too fast 2. when it's raining we cover ourselves to not get wet, but we create rain to get wet in the form of showers etc.
We need to start eating more bugs. The biggest thing we can do is cut down on large livestock ranching (cows, pigs and sheep) They are disastrous for the environment, greenhouse gas creation, obesity epidemic, global poverty and the water shortage. If we were to replace even half of our consumption of these animals with other sources (insects for example) the world would be so much better off. The University of Wageningen has published a really cool report on this.
I'm under 18 and I felt that 1 way to save more water was to reduce the rate of *Global Warming* ,to reduce the rate of *climate change* so that the temperature will not rise.The rising of temperature results in more usage of water(drinking&stuff),hence waste more water. So in order to reduce the rate of *Global Warming* ,us people can plant more plants,reduce the usage of cars,use more bicycle instead and limit the amount of water used by afluence,those afluence keeps wasting resources. Many people might think that its their business,but their action affects all of us.
I am so glad TED Ed made this video. Over 15,000 scientists have claimed that if the world went vegan it would stop climate change, for the majority. Obviously, this isn't the most practical thing to do with culture and people's lack of adapting to this lifestyle, but it is a definite move towards saving our beautiful Earth.
Well all you need to do is like the island i live on, we pump water out of the ocean,purify it and then re-add some important minerals since the water would be so clean
@@emelgiefro I know that "nobody cares" but what he said was relevant towards the video even if he did sound somewhat narcissistic. But being vegan helps a lot. Have you thought about reducing your meat consumption? It would help tremendously. Eating a more plant based diet could reduce your environmental footprint. It could reduce land use, water use, emissions, and more. I'm not asking you to go vegan, but I am asking you to please try to eat something more plant based at each meal. Please try it out sometime and look up more research about it. There are many documentaries such as "cowspiracy". Please have an open mind and give it a watch. :)
@@kazumades5283 Taking shower instead of bath will help too. Current situation isn`t that bad tho. We don`t need to make meat illegal to live. We have to thing better way to pure water and it will be ok. Global warming is much bigger problem, and not as easy to solve.
@@pohenixwielki3178 I do agree there are other things that we can do to help. I also never said "we should make meat illegal". However I do think you are belittling how much animal agriculture actually destroys the environment. Feel free to join our discord server discordservers.com/server/363108109797031936 to talk to vegans/omnivores about this subject. We cover health, ethics, and the environment. I didn't come here to give you statistics, but trust me when I say there is an overwhelming amount of evidence. If I gave you it, you wouldn't want to read paragraphs about it. If you really feel doubtful about it. Join our discord server, tell me your username and we can discuss this.
Agriculture would use up an EXTREMELY smaller amount of water if we cut down on meat consumption. This is not a vegan point of view, but an environmental one. We feed the animals we eat more plant food than we ourselves consume. The production of livestock meant for meat is responsible for a ridiculously big amount of water spending. If we all reduced out meat consumption, we would do wonders for out water reservoirs.
A video that goes deeper into the underground aquifers would be great people who don't live around a huge one don't understand the importance of them being preserved.
I'm not sure if any countries do this, but how about a tax for high water-consuming products, something similar to the carbon tax that already exists? 'Cause suddenly, companies get even more interested in reducing costs that pollute the planet, while people feel in their pockets the consequence of pollution. Wow, i even felt a bit of eco-extremism from writing this.
I kind of hate it when people use "olympian swimming pools" or "football fields" for measuring lengths or volumes. We have measuring systems here, hello???
