This makes me feel a lot better about using water. I always felt like I was completely destroying the world when I took a shower. I'm not going to go out and use more water now, I just don't feel as bad for using as much as I do.
Lots of places DO use surface water for everything, though. In BC, where I live, we get our everyday tap water from a lake atop a nearby mountain. It basically sustains a city of 12,000 people every day. But we get rain like nobody's business, so it's different.
latitude and longitude lines cross at 90 degrees, so the shape of the country is distorted, but the areas are more close to real life. this makes it easier to compare countries by scale. its not used much in the west because it makes Africa, Australia and south America look bigger than the US and Europe, which they are.
Currently taking an environmental science course and the whole thing is about water and how to conserve it. People are actually trying to figure out ways to be able to reuse water. Right now, some ecofriendly buildings actually reuse water for their toilets. Some use rainwater for sewage and whatnot. But they haven't found a way to reuse water for drinking...so my teacher believes...
The narrator's voice gives me the shivers, not to be rude or anything but she sounds like she's on the verge of crying because she is scared. Does anyone else think that? xd
Salty water would mean that there is a higher amount of solute outside of the plant cells than inside. This, in return, draws water out of the plant through osmosis and dehydrates the plant cells. This is called a hypertonic solution. As an experiment, try to drink salt water for a while. Sure it tastes bad, but what you'll notice is that you increasingly become more and more dehydrated. This is why we don't pour road salt over plants during winter as well.
In a lot of areas, ground water is not replenished at the same rate was which it is used, and you see the ground water level go deeper. Even in rainy Vancouver. The wells in Langley see the ground water levels decrease and get contaminated by surface use.
"There's no life without it" untrue. But this is about the importance of water, after all. And it is important. Most life on Earth requires it anyways, so.
(from cont.) and uses something similar to Oxygen. We already know organisms that do not use Oxygen, but water is dipolar, so it has a wider range of things that it can dissolve. dipolar means both acidic and basic. Bases and acids are the same dissolving power based on how far from 7 in pH they are. Water has a pH of 7, but can dissolve many, many things.

Talking about porcentages is misleading. The amount of fresh water in the world may seem minimal in the context of oceans, but is a lot more we will ever need.
Using the periodic table, we can discern, and know experimentally, that Silicon acts like Carbon, making the range for Silicon-based life forms wider, and making it very interesting to see what type of liquid at higher temperatures they would use. But, there is more Carbon in the universe, because it takes less time for stars to create it. And so far as we have observed there is no life without water. There needs to be a compound that acts like hydrogen does with those weak bonds (cont.)
Many think when talking about water problems like, what are they talking about? Water forms 97 percent of earth! Forgetting the fact it's not all drinkable water.
I wonder if fracking uses fresh water or salt water. Since fracking puts water into the ground that can not be recovered so it doesn't seem like a good idea to use fresh water for fracking.
do i have to be the one to add that in the US the grass on our front loans we use for aesthetics only in the #1 consumer of our fresh water. yes world, America may be powerful as hell but most people here aren't that smart, the better of us are working on it but we'll see. kinda like the penny, we still use them despite it costing more to make that its actually worth. aren't we supposed to be teaching facts here?
I guess you've never heard of desalinization. Methods have been invented but it's very expensive. Some countries use it... and when the fresh water supply gets stressed, more countries will follow suit.
It would be better of the diagrams are proportional to the percent of the contents. You divide fresh water into 3 parts, but 0.3% should not look as big as 70% .
@Alec McKinney fences can be use as minerals for crops and trees. It is actually isny bad for your health because feces break dowb by bacteria then the trees use that mineral to grow. feces, dead animals and other dead stuff help crops to grow; that has been going on for million of years
not 9.7% missing they went over by .3 % 70+30+.3= 100.3%. i just assumed since surface water is so small they just excluded. But also agree water can be used in more then one event if not consumed such as power and drinking water. This would be hard presentation to make though with water renewal through the water system its hard to really calculate water use and amounts.
I heard on NPR that there are some farms in third world countries that actually use tainted water. I'm sure there is a process to filter the water but in the end it is still dirty water. One farmer claimed that he gets more yield by using dirty water than anything else. Especially effective on his bananas. I think its on some farm in south america.
We can use any water on Earth, whether it be fresh water or salt water. Of course we would need to desalinate that water, but then we would have a nearly unlimited supply of water. People just don't want to spend so much money on a basic human NECESSITY.
Duuude I had no idea what you're talking about. O__O Layman's terms please. Haha. Anyway, I'm not here to argue or something. But I believe that without water (fresh or salt water), we will all die, plants, animals, humans, everything. If other "periodic elements" can be an alternative to drinking water, then that'd be great. :)
I think some water is not totally treated after domestic usage and so recycled as farming water. Then again, domestic water is just a drop in the bucket.
Indeed. And in African countries, all they need is invest in solar energy, use sun's energy to distillate and basically have plentiful of fresh water! All those billions of dollars western countries pour in Africa could be directed in this project and make Africa self-sustainable. If only politics is focused on long term... we'd all be in good shape.
Ohh, no, yea. I'm talking about outside of Earth's ecosystem. Also it's not arguing it's discussing. :3 Oh uhh that's a bunch of Chemistry stuff. There's some nice videos on chemistry education here on youtube. Like crashcourse and khan academy maybe.
We can't use salt water because the salt would build up and become toxic in the soil. Thus, killing everything that grows. We don't use dirty water because it contains a large amount bad bacteria, minerals, and chemicals. Do you really want the food we eat to be grown with dirty water?
Were talking about water that contains human waste and toxic chemicals. If the human waste is free of harmful chemicals it can be composted but it takes a lot of time. But then again, the idea makes me feel squeamish. Just like the story on the Japanese scientist who can make poop burgers high on protein...
I know water is a compound of H and O. Cant you see I used his own words? (That's why "periodic elements" is in quotation) Try not to meddle with other people's discussions without reading first. Cheers.

Water is something that never goes away.. it transforms, renews and recycles... and always will. We can never kill water. That is a fact.
Water is recyclable since we live in a biosphere. As long we don't pollute our rivers and skies, our water will always be available to us.
I wish they'd re-record this with someone who wasn't wavering so much vocally. The info and animation is great though.
Still we should have respect for her

@Sebastian Hellums u suc
very much helpful from the point of view of my lesson
Absolutely brilliant!!!
Thanks for the lesson, it has given me a good idea on how to start my university essay.
IMO, what she said is true. Early forms of life came from and lived in water. So there really is no life (to begin with) without water. Peace. :)
Very quick! synopsis of global water consumption- Serves as great into for deeper exploration of water or tangential topics

I have been saving rain water for years for use around the yard,. It's not that much just about 200 gal.when full.I keep my consumption down.
don't cry boo, water isn't gonna hurt you~

water used to produce electricity is also used to grow crops, for human use and of course in industry. something smells wrong in TedEd land

Great short
Nice video, thank you ted ed.
Wow, very nice. Didn't know that about water.
..aw. .... she is worried that we got less water... please don't cry lady..
So... i'm assuming we don't have to worry about fresh water for a while... right...?
o~o
why would you think that
Is there anyone who's watching this video during lockdown? If yes then please like👇.
@Leon Detavernier 🤦🏻♂️😂😂
@Leon Detavernier I can very well understand your condition. Btw is this a homework that you've to complete within the lockdown?
Didn't think we only had 2.5 % freshwater... that gives me worry XD.
she does sound kinda worried and concerned

What about the water in the atmosphere? Does that account towards "surface" water?
In the future could we purify ocean water efficiently?
How about just "other compounds?"
doesn't tell when we won't have enough
Why can't we have seawater drying beds to convert seawater into salt and fresh water using the sun?
0:43 das not how you use literally
Not as much as it could. We pollute the water so at some point it gets unuseable :/
What about the water in the atmosphere? Is that also surface water?
What about living beings? Who much water do all the living organisms on Earth hold in their bodies?
It is a very very small amount. It may seem like a lot but it is actually not.
If we invested to make the process of desalination cheaper, we could use water from the ocean, making 70% of the world drinkable.
sorry, i got it confused with the Gall-Peters projection
Now I feel scared about what would happen if all fresh water were to be gone...
Because Brawndo has what plants crave! We're scary close to the prediction in the movie "Idiocracy".
People get nervous sometimes.
the voice sounds like about to cry...
0:43 There's nothing quite as ironic as using the word 'literally' figuratively
We can't use salt water because the salt would build up and become toxic in the soil. Thus, killing everything that grows.
We don't use dirty water because it contains a large amount bad bacteria, minerals, and chemicals.
Do you really want the food we eat to be grown with dirty water?
It's a global concern, but aways demanding local attention.
In what way?
actually human waste can be used as a fertilizer, but it can contain pathogens, so its not recommended
That wouldn't be a bad idea if we didn't consume so many chemicals
only 8%? That makes me feel alot less guilty over wasting water by taking long showers...
Why can't people use salt water or dirty water for agriculture
Were talking about water that contains human waste and toxic chemicals. If the human waste is free of harmful chemicals it can be composted but it takes a lot of time. But then again, the idea makes me feel squeamish.
Just like the story on the Japanese scientist who can make poop burgers high on protein...
What about the Sea? You didn't mention it???
I know water is a compound of H and O. Cant you see I used his own words? (That's why "periodic elements" is in quotation) Try not to meddle with other people's discussions without reading first. Cheers.
I feel nervous just after watching this
why cant we just turn alot of the salt water into fresh water by cleaning it and taking out the salt?
I just don't get it. There must be a lot of water because I drink one gallon a day. That is crazy. Anyway, I am glad to be an American.
I like turtles

its more accurate
How much goes to watering grass?
