The Global Water Crisis - Bytesize Science

Actually now there are people that have made bill boards (forget where) that take the humidity out of the air and turn it into drinking water. Its in a place where the humidity is around 98% so its worth the while. But we are finding very clever ways to get the water back.

Fresh water comes in many instances from aquifers that have been around for millennia and are being regenerated much slower than they are being depleted. Most of water that is used will end up in the atmosphere, and most rain falls on the ocean, so we are turning drinking water into undrinkable water. There currently is no cheap, energy efficient way to turn salt water into drinking water.

Water is a closed cycle. We may have problems with distribution but not supply. The same is actually true of fossil fuels. We will hopefully learn to speed up the cycle.

[@simonnance]

unless you plan on using fossil fuels at the same rate as they are being produced, they aren't "closed cycle". Water's persistence in the atmosphere is very short (though most of it rains in the ocean, and salt water isn't drinkable), CO2's isn't.

I don't get the argument, that we need to speed up the development of bio fuel, "that doesn't need land and water". But of course there is a huge need for land and water, specifically for bio fuel, because it has to grow somewhere, right? Some arguments seem to be very confusing to me.

[@nemodot]

are we dumping fresh water into the sea? I thought only rivers did that. But there will always be precipitation and we can stop loosing the fresh water by building dams. There's water in the ground that gets renewed every time it rains. I mean, there will never be huge ships filled with fresh water like today's oil. I hate that comparision.

[@Jeffmorgan1991]

Fresh water is though as we keep dumbing large amounts of it into the sea

[@ladywhyasker]

Ten minute showers are inexcusable? Yes, those guys are the worst. Not the water polluters or those who refuse to fix leaky water systems.

[@brageallum6995]

I think she means fresh water is finite

[@Koba4329]

@ 1:59 "we need to try and find solutions" hahah... get it, solutions... water.... yeah

[@nemodot]

How is water finite? Is it going out of the planet? Water is not the next oil. That's absurd.
