But many people despite the fact that there is no alternative to water, objects to its high cost. There was another solution that recycled water should be used, but no country has come to accept that they want to drink or take a shower with water used for their tooth brushing and toilet use. So the best and only alternative now is to use sea water. It is not a new phenomenon, since the Middle East where is also scare rainfall and thus less water has been using desalination plants for decades. As the population of the world explodes especially in the poor countries, there will be an increasing need for water and the only other solution besides the so called conservation (which you would have to teach to developing countries people) is desalination. You know people still see water as an infinite resource and they waste it ruthlessly. But as global warming becomes a phenomenon, water is being increasingly seen as a finite resource.
It has been said that the next wars will be on the basis of water. It is already become true like in states like Georgia accusing the neighboring states of siphoning off their water. And India is being accused by Pakistan of building dams on the rivers and stopping the water to the agriculture crops in Pakistan. There is increasing pressure on the Colorado River on which several western states depend on for their water supply.
