"Water is the greatest of all things," said the Greek poet Pindar. Many scientists presume that life itself began in water. There could certainly be no life without it; most living creatures consist mainly of water. But what if one day there were no water? Why should we care about the water of the future, and what can we do about it?
Flip through any science textbook and you'll read that water is renewable, that although it's used, it is never used up. But water usage is increasing. Although water covers three-fourths of the earth, 97 percent of it is salt water, and more than two percent is frozen in glaciers and icecaps. That means less than one percent of all water on this earth is usable, while water usage per person averages 100,000 gallons per year.
The world's six billion citizens are already appropriating 54 percent of all the accessible fresh water. United Nations' research shows that by 2025, we will use 70 percent - and this calculation reflects only the effect of population growth. If per capita consumption of water resources increases at its current rate, we would be using over 90 percent within 25 years, leaving only 10 percent for all other living creatures.
There is also another problem affecting the water system - pollution. Human and other animal wastes, toxic chemicals, metal and oils all pollute. To illustrate the problem, let us go to Milan, Italy. Doesn't that sound romantic? This famed city is where fashion designers come to seek fame. Is your mind filled with images of magnificent trendy shops? But, hey, hold your breath - Milan has the highest recorded level of sulfur dioxide pollution of any city in the world, which not only causes air pollution but also contributes to acid rain. Sulfur dioxide is a heavy, invisible and poisonous gas, and is the most widespread man-made pollutant. It's used as disinfectant, refrigerant, bleach, and food preservative. When absorbed by water vapor, it turns into acid rain and poses a serious threat to the environment as it increases the acidity of soils, lakes and rivers, endangering organisms. In Great Britain, an estimated 67 percent of forests have been damaged by acid rain.
Italy's longest river, the Po, now has pollution 10 times higher than officially recommended. It is estimated to discharge 250 tons of arsenic into the sea each year. And it's not alone - according to a 1992 water resources survey, 40 percent of America's rivers and 45 percent of its lakes are impaired or in poor condition; the leading polluter was agricultural chemical runoff.
Many governments have limited the amounts and kinds of waste that can be dumped into water. In addition, nations, states, cities and various industries have spent billions to reduce pollution and construct water treatment plants. But pollution has not stopped. Many cities still release untreated sewage into rivers, lakes and coastal waters. Some factories still discharge largely uncontrolled pollutants into the water through their sewer outlets or factory drains because it would cost much more to manage the waste.
in the end i would like to say that..
save the water here and there and dont waste it anywhere!!!
hope this helped..
