A new study warns that about 30% of the world’s people may not have enough water by the year 2025. A private American organization called Population Action International did the new study. [23]It says more than 335 million people lack enough water now. These people live in 28 countries, mostly in Africa or the Middle East. PAI researcher Robert Engelman says [23]by the year 2025, about 3 billion people may lack water. At least 18 more countries are expected to have severe water problems. The demand for water keeps increasing. Yet the amount of water on Earth stays the same. Mr. Engelman says the population in countries that lack water is growing faster than that in other parts of the world. The report says lack of water in the future may result in several problems. It may increase health problems. Lack of water may also result in more international conflict. Countries may have to compete for water in the future. Some countries now get 60% of their fresh water from other countries. [24]And the report says lack of water would affect the ability of developing countries to improve their economies. The PAI study gives several solutions to the water problem. [2510ne way, it says, is to find ways to use water for more than one purpose. Another way is to teach people to be careful not to waste water. A third way is to use less water of agriculture.
