water scarcity in future ? is it true ?

Question

I read a lot, heard a lot about pepole talking about fresh water is going to scare resource in future ? there will be politics, war all for the fresh water.
can somebody tell will this happen and why ?
and if yes, by what time or year it happen ?
its not possible to predict the time but if things keep on going this way, One country that is U.S. keep consuming the natural resources and keep contributing in pollution and global warming at current pace, how far is that situation from today.

Answer 1

Yes is very true rivers are drying out and there is less and lees fresh water overall

Answer 2

It already is, in certain areas. Out in the western US, for instance, everyone's battling about damming up rivers and draining them off. It's a real problem, especially with the drought conditions so many states have seen for the past few years. Even here in the East, where we look at our basements (now indoor pools) every spring and laugh bitterly at the word "drought", we get into some pretty serious fights about the factory upstream killing all of our fish and giving our kids cancer downstream.

How much longer can we keep doing all this to our planet? Not much. The experts gave us ten years (two years ago) to change our ways before the damage due to global warming was irreversible, and there are those who think that was too generous. We're seeing the effects now to the point where even energy companies are like "Oh, sh!t". You're right about the US (although China and India are going to be major competitors for Worst Polluter Ever status soon enough), and the sad part is, we have the technology to make the changes already.

Answer 3

Fresh water shortages is a distinct possibility, as a side effect of global warming. Most fresh water supplies come from glacial runoff or from other forms of melting ice. Ice naturally melts and freezes as a part of the seasonal cycle, but if the global temperature rises what will end up happening is glaciers vanish, effectively turning off the source of fresh water.

Now we'll always have fresh water, but what happens here is the fresh water gets very localized--some areas will have plenty, others will be locked in a permanent drought. People living in water-deprived areas will either have to pay to have water piped in, or they'll move to an area with fresh water. Of course, that presents another problem in that once everyone starts crowding around the fresh water sources that remain, those sources will begin to dry out as well.

Eventually I think we're going to end up building a ton of desalinization plants all along the coast, in order to turn seawater into potable water. No matter what happens though, it's going to be expensive. Better to act on the problem now and do everything you can to stop global warming!

Answer 4

I believe it will happen. As we inhabit areas without fresh water such as inhabit the desert and then water it to make it green, ex. Palm Beach California, and have to tap into other fresh water supplies to bring water to the area, there is less water available downstream. As those areas become more populated, there just won't be enough water to supply the needs of all the people. San Antonio relies on an fresh water aquifer and each year there is less water and the population is growing. I live at the end of the Rio Grande River and it is a real concern here. There are discussion about building desalinization plants-to remove the salt from the sea. I know that the US uses more than its share and it needs to stop but as far as pollution I see much more pollution coming from south of me in Mexico. There are tons and tons of raw sewerage dumped into their rivers and little to no environmental controls. When they burn the crops way down in Mexico, the air is full of smoke in Texas. I have been in Mexico and it is like driving through a fire. I see multinational companies moving to countries that don't have strict environmental controls. They don't move to these countries just because there is cheap labor, there has to be more and a lack of environmental controls is a big money saver. These are the corporations that need to be watched and controlled. Everyone needs to join in to help save our world.

Answer 5

You're late. It's already happened. Coca Cola and Nestles have bought all the water bearing land they could in Europe. They are working on the US and Canada now.

Answer 6

This may happen in the next 1 million years. We have enough bottled water until then. Don't worry.
