Human footprint of water shortages

In a sunny autumn morning, we drove on the highway along the river.My mother and I looked out of the window and stared at the river which my dad just told us that it is Colorado River.Couple minutes later, my mother turned aroundand said, “En, well, it is not river.Actually, we called it stream in China.In my mother’s mind, a river must be a lot wider and deeper.My dad told us that is was not its original appearance, and he did not know when the water in the river got le and le.It is not only Colorado River, but also all interstate rivers in US and the

rivers all over the world are facing this situation.After the pa few weeks, I researched some information about how populationgrowth effects the water resource of Colorado, United States, and the world.As the population growth, the problem of water shortage became more and more serious.In 2011, there are nearly 6.5 billion people on the earth.If everybody in the world joins their hands, they would encircle the earth 16 times.Today, many countries face chronic water shortages due to intense population growth, such as overusing river water and underground water, lacking acce to safe drinking water, and people waste a lot of living water.Overusing river water and underground water is serious water problem we have to face.In the United States, there is longstanding friction over use of the Colorado River, as well as other interstate water squabbles.Affluent river water was dumped out for agricultural productivity, energy

production, high-tech manufacturing and other heavy water-use industries.In China, a super big city is called Shanghai which has a serious population growth problem, and it doesn’t have enough water to support the big population.The government figured out to use underground water to support the urban area.But now, because underground water was

overused by people, Shanghai sinks with the speed of one centimeter every year since 1990.Clean and safe water is the lifeblood of healthycommunities, healthy

ecosystems and healthy economics.According to Peter Gleick, president of the Pacific Institute for Studies in Development, Environment and Security,“Forty percent of the world's population — that's 2.6 billion people — lack acce to sanitation services, which leads to hundreds of millions of cases every year of water-related diseases.The fastest population growing area of the world is Africa.Today,many Africans daily per capita water consumption le than the water Americans use to flush the toilet.The world’s biggest problem today is our failure to meet the basicneed for water for billions of people.The Environmental Protection Agency has proposed new ways to regulate water pollutants, and economists say charging more for water would promote conservation, but whether Americans will pay more for a resource that many view as a human right remains to be seen.
