You can't use up water. The water now is the same water we've had millions of years ago, but pollution can make water toxic to use. If you want to conserve water, then just don't pollute it.
In about 150 years everything will die

Pollution is not a threat to the rain forest. In fact pollution has mostly gone down in the last 100 years.
Uganda is a small country that lies in the mid-Eastern part of Africa. It was settled thousands of years ago, but officially gained its independence in 1962.
No, pollution did not decrease yet. Hopefully in the future it will though. I actually think that pollution has gotten worst over the years.
Water pollution has existed for all of Earth's history. Animals and fish die in the water, herds stir up sediments, towns discharge sewage, heavy metals dissolve out of rocks. etc. The problem is tha larger human settlements and increased industrial and agricultural activites are discharging more and more pollution into localized areas.
There are many forms of water pollution. Most natural. A deer that urinates into a stream has polluted it. Most people only consider man induced water pollution though when they refer to this subject though, as this is the worst form of pollution. Man induced pollution is the most preventable and the worst in terms of length of endurance. Pouring pcb's into our water will keep life from developing or surviving for years. Some pollution of the eco system is not avoidable without causing death of our population too! Pesticides are required by farmers to give us the food we need. Over use of pesticides causes problems by flowing into our water eco system. Some people feel we should allow millions to die and stop all pesticides. Other people feel that this is a small price to pay for modern life. The truth is (as almost always) somewhere between. No matter what your stance is, we should all be able to agree, the less man made pollution, the better.
right now is 2011 , in a few years its all out, without water we cant make food, or drinks so save that water theres going to be no more!!
