Hey, she's from Crash Course Physics!

[@lynnleigha580]

One thing I don't understand is why collecting rain water is illegal. Here it is (Illinois USA) last time I checked anyway. I find that absurd, if done properly, I believe it would save so much drinking water. I'd rather use collected rain water for my gardens and lawn during the dog days of summer when we go forever between rain days.

[@mehitscool]

only possible reason i can see why is attracts mosquitos/unwanted bugs. I;m from cali.

[@fwh79FOXR6]

LLB MAGA: You know that IL would find a way to tax you for your collected water.

[@covercalls88]

The thinking is that the water belongs to everyone and no one should collect water for just themselves. I believe certain cities and counties in Oregon has such rules against water collection. In Los Angeles the city offered rain barrels for people to collect rain water as most of rain water flows into the ocean.

[@BhangRonBooks]

You should know one thing. The rainfall is not belong to only human. The nature needs a rainfall. a tree, an animal, a bugs, a grass, etc

[@Urallrobots7313]

Government has to regulate everything so they can keep making money

[@treelife365]

Most interestingly, in modern times, we built our societies on the idea that water was abundant and unlimited...

Bring back this series.

Great well rounded documentary as always and a bit off topic, but AJ you are making an impact in the West, I'm a white British national and from the work of Al Jazeera and others I'm more informed about the world and care more about everyone because of you - you are creating more love in the world by reconnecting people to it with matter of facts, thanks. It will be very sad for humanity if the Gulf nations against Qatar get their way, you are helping to change the world clearly.

[@treelife365]

May I politely ask what your intention of mentioning skin colour is?

[@areskimeziani839]

al hamdoulilah, at long last something worth watching from AJ

[@ThorusCrusius]

1. What impact on the eco and bio system does it have if water is gained out of the air and of fogg? - Yes things are becoming dry. Desertification! Don't need to be a scientist to get this conclusion. 2. Doing laundry is not just about filtering purple colour out of water.

[@umaribnal-khattabmalaysia6831]

Every year how much rainfall the world received? How much rain water we stored every year ?In United states alone how much rainfall every year? Why we are going to use expensive things to store water why we not more cheaper things like to make small rainwater dams and lakes etc.

[@saintz177]

Good jobz. Lads keep up the good work. For humanity

[@dougwedel9484]

Trees catch water from fog. They introduce it to the soil at the top of a hill where it can trickle down the hill to supply the hillside.

[@berisf]

I think we need to protect our waters more... aw, couldn't lie about it- get a bit nervous sometimes seeing this- don't like our animals getting hurt or our waters being contaminated. Imagine what it would like? I miss it too much- want to swim deep in the sea!

[@MariasBelieves]

I want those washing beads like now in America at my local grocery store. I am all about saving at water as much as they charge for water consumption in Michigan.

[@fwh79FOXR6]

So... the real "problem" is humans.

[@BhangRonBooks]

19:30 아예 빨래를 공동으로 하는 것도 한 방법

[@Gvtteddybear]

How are the beads cleaned and reclaimed? Is this energy efficient?

[@zachfox7771]

im assume that a metal mesh would work the best, especially if the metal is cold( could be cooled)

[@fwh79FOXR6]

Most metal is very corrosive.

[@zachfox7771]

fwh79 yeah, it would want to be stainless for sure

[@Mygreenaccount]

Where can I find the sources of this information?

[@fritzstehr]

By 3:33 the doc had so frequently jumped madly from scene to scene I left because I don't like getting blinked off as if watching a TV commercial edited by a meth freak. However, if the doc was aimed at 2 year olds and dogs, it makes perfect sense to provide blink off for viewers with super short attention spans.

[@markmahan38]

Messing with weather is a bad idea. Extracting moister from the air will have causal affects that will only cause a runaway climate disaster more complications. When the solution are much simpler. And makes water a communal asset rather than a commodity. Recycling of water at the base of use, is one way to conserve water. Growing food with technology that is intergrated at the point of housing is yet another way to conserve water. Just 2 examples of water recycling and conservation. A 3rd would be rain water collection and use to water gardens and lawns.

[@menonjaya3784]

Why nobody trying to manutwvture water. Or squeeze water from the air above the seas

I think that host has constipation due to drinking of contaminated water

[@michaelsabella5924]

this is great but I hope these folks are also concentrating on some 3rd world countrys where they have no rainfall or only have access to very dirty water. I see many charities raising money to drill wells in those areas. Certainly not any gfog at all of evern close to the oceans.

[@Danybella]

TOO MANY ADS Aljazeera!!!!!!!!!!!!!!!!! thumbsdown

[@cipndale]

And humanity pretends to colonize Mars :D

I'm for conserving water but this is just more bunk from Commiefornia.

[@ranstan4557]

fake news

[@julespeace684]

Why can't we build a reverse osmosis from the ever rising sea and melting snow cap runoffs? Yes we have climate issues but we have 5 oceans and seven seas... Hello, they are doing it in the UAE... Think people!

[@r3dp1ll]

Actually it was developed and expanded in Israel. Several plants are being built right now around the globe. They will be more and more common
