Update:
Removing salt from water is called "desalination" homes. It's most popular in the Middle East where most countries use it for agricultural purposes. Removing all the salt from the water, although easier nowadays, requires energy and thus can generate pollution (just like our bottled water now). Orale.
The UN owns Yellowstone National Park. A lot of fresh water comes from these mountains and our own Government gave it to the UN. Ha! And people think the UN is acting in people's best interest. Does anyone else see Global Governance here?
The Polar Ice caps aren't going to disappear. Glaciers retreat and grow over time. Science knows this, but environmentalists will propagate this information freely for the uneducated. When you understand where our information comes from and how it is used to manipulate us into thinking there are catastrophic events coming due to humans existence, then one can understand that we are being duped into believing this.
Read some facts before you start blathering about the poles melting completely.
Have you not noticed that there are no glaciers in the UK, but all these rivers and streams of fresh water all over the place?
Distillation is a means of purifying water - water vapour evaporated from impure water (eg. seawater) leaves the contaminants behind and is re-condensed as fresh water.
That's happening all the time - it's called Rain...
Two thirds of the world surface is covered by water - that's enough to keep it raining.
(Also, 'reverse osmosis' purification of Seawater would still cost far less than we pay in the UK for water rates, but rain is free so the water companies prefer that...)
There is a process that gets the salt out of salt water (ocean water) but as far as I've heard it's a bit expensive to actually go through with. That and if the ice caps melted we'd probably find some way to get water. Like wells, lakes, and what not.
This and a lot of other Idea's view's people should be thinking about Population, Pollution,Renewable Energy,Sustainability and if the ocean's are the source of drinking water what of the salt byproduct ?. It can not be pumped back into the Ocean's as it would become as Barren as the Land and even if Life can be created on another planet only about 6% of the population would go. The rest to die with the Earth Medical Science has made some amazing Discoveries and Cures but has thrown out the Natural Balance of life I myself should have died years ago.
That is certainly something that you should be concerned about, and the problem is already surfacing even though the ice caps are just beginning to melt. The higher temperatures from global warming increase the vapor pressure of water and thus the amount of water in the air. But it is also causing causing more extreme temperatures which increases the rate of evaporation from soils. The net result is that in areas that get their rain from ocean patterns are seeing an increase in precipitation and floods, while the interior of continents are experiencing greater evaporation which leads to droughts.
The Pearson drought index for the latitudes at which food is grown is now about -2, which indicates the areas are under drought conditions. Not only are ponds, aquifers, lakes and rivers drying up, but the drought conditions are causing a reduction in crops and livestock. So part of that world will get plenty of water from rain, perhaps too much, and part of the world will become like desert.
Those areas around the oceans would be the only ones to benefit from desalinization, but it may not be needed if they're experiencing more rainfall. Depending too much on desalination is a bad idea as it requires a tremendous amount of energy to desalinate ocean water, and using fossil fuels to do it would just make the problem of global warming worse.
If the polar ice caps melted there would be increased precipitation (rainfall) so there would plenty of water from rivers, lakes, reservoir's etc
Same places we get it now. Rainfall and groundwater. Polar ice caps would take several thousands of years to melt. We will not be affected in our lifetimes.
As long as we have enough money, we have the technology to deal with it.
Because that's one thing I'm worried about, so how would we live without glacier water? Or is there enough science in the world to purify the sea water? Or would the sea water be less salt concentrated so it would be easier to purify ( if all the caps melted completely) ?
I suppose dams/reservoirs would be bigger
