Water Fight!: Crash Course Kids #36.1 - By Crash Course Kids
Transcript
| 00:09 | we've talked a lot about water , you know a | |
| 00:12 | lot about water and that's a good thing because without | |
| 00:15 | it , none of us would be here . Earth | |
| 00:17 | has a certain amount of water that's been circling the | |
| 00:19 | globe for millions of years . Remember that you're drinking | |
| 00:23 | the exact same water that the dinosaurs used to drink | |
| 00:26 | . You also know that the vast majority of the | |
| 00:28 | world's water is in the ocean . That's great for | |
| 00:31 | whales and clown fish and octopus is , but it's | |
| 00:34 | too salty for us to drink . So instead we | |
| 00:37 | let nature do the work through the process of evaporation | |
| 00:40 | , condensation and precipitation . Does this sound familiar ? | |
| 00:43 | The water cycle evaporation takes water from the surface of | |
| 00:47 | the ocean and turns it into water vapor , leaving | |
| 00:49 | the salt behind . The water comes back down to | |
| 00:52 | earth in the form of precipitation , rain , sleet | |
| 00:55 | and snow . This fresh water is all the water | |
| 00:57 | we'll ever have . It's a limited resource in a | |
| 01:00 | closed system Now . We've also talked about how people | |
| 01:03 | sometimes change the level of fresh water they have access | |
| 01:06 | to buy polluting , damning and over using water . | |
| 01:10 | And we saw what happens to animals , like the | |
| 01:11 | vaquita and freshwater fish in the Elbe River in Washington | |
| 01:15 | state when we mess up the water supply . But | |
| 01:17 | what happens to people when there's less fresh water ? | |
| 01:24 | The short answer is when access to water goes away | |
| 01:28 | , it can get pretty scary . Of course we | |
| 01:31 | need water to drink . That's a biggie . But | |
| 01:33 | we also need water to grow crops , keep toilets | |
| 01:35 | running and make things and we use water for a | |
| 01:38 | bunch of other stuff like washing our cars and keeping | |
| 01:41 | our lawns green . So to see how people are | |
| 01:44 | affected when there's less fresh water available , Let's take | |
| 01:47 | a look at some places that don't have quite enough | |
| 01:50 | . And then our investigation starts in sunny California , | |
| 01:56 | maybe to sunny California as of today , California is | |
| 02:00 | in the middle of a drought . A big one | |
| 02:02 | . It's not raining as much or as often as | |
| 02:05 | it needs to . On top of that . Southern | |
| 02:06 | California is at the end of the Colorado River for | |
| 02:09 | millions of years . This river flowed from the Colorado | |
| 02:12 | mountains all the way to the sea where California meets | |
| 02:14 | Mexico . But today the river often dries up before | |
| 02:18 | it reaches the ocean . So less water gets to | |
| 02:20 | California than before . So what goes on when California | |
| 02:23 | doesn't have enough water ? Well , you know what | |
| 02:25 | can happen when there's one really cool toy in a | |
| 02:27 | room full of kids . The kids fight in , | |
| 02:30 | California produces nearly half of the fruits , nuts and | |
| 02:33 | vegetables grown in the United States . So how much | |
| 02:36 | water that California has access to has big effects on | |
| 02:39 | lots of people . As a result , water scarcity | |
| 02:42 | is creating conflict . Do I get to flush my | |
| 02:45 | toilet or do you farmer joe in California get to | |
| 02:48 | water your crops to work out disputes like this ? | |
| 02:50 | The fight for water is taking place mostly in courtrooms | |
| 02:54 | . For example , some people in California are pushing | |
| 02:56 | for new laws to regulate who gets how much water | |
| 02:58 | and many other states are experiencing drought too . So | |
| 03:01 | the conflict isn't just confined to California among all the | |
| 03:04 | states along the Colorado River arguments are breaking out about | |
| 03:07 | who gets how much water from the river . And | |
| 03:09 | these arguments are raising big questions . Like do we | |
| 03:12 | keep sending water to cities in the desert , far | |
| 03:15 | away from the river , even though those cities close | |
| 03:17 | to the river are low on water to and do | |
| 03:19 | we like farmers use the water so that they can | |
| 03:21 | keep working and growing food ? Or do we send | |
| 03:24 | it to homes so that people can take showers and | |
| 03:26 | cook dinner ? These are tough questions , and the | |
| 03:34 | fact is the problems in California aren't new . Water | |
| 03:37 | has been a major source of conflict among people in | |
| 03:39 | different parts of the world for thousands of years . | |
| 03:42 | Next time we'll take a look at different ways people | |
| 03:45 | are responding to the scarcity of fresh water and maybe | |
| 03:48 | it'll spark ideas from you to help find a solution | |
| 03:51 | to our water problems . |
