全球淡水资源短缺英语作文 1
The water crisis has become one of the most urgent challenges worldwide. According to statistics, over 1 billion people worldwide lack access to clean drinking water, and 3.1 million people die each year from diseases caused by contaminated water sources; 2.6 billion people worldwide lack access to basic sanitation facilities; And residents in developing countries spend a lot of time walking more than 6 kilometers every day to fetch water. These data are deeply shocking and thought-provoking. We must seriously consider why such astonishing numbers have emerged?
Chinas rivers are like clear jade belts, quenching our thirst and nourishing our fields every day, nurturing our future generations. However, it is often indiscriminately discarded by people, which pollutes the river and harms our benefactors. We should cherish the river water, protect it, and let the clear water flow forever.
Every drop of water, every river, we cannot waste it - it is our benefactor.
The great river is the source of our life, nourishing us and we also rely on it. From ancient times to the present, we have formed an inseparable bond with the great river, but have we ever truly appreciated it?
Lets cherish and protect water from today!

The concept of obtaining fresh water from icebergs that are towed to populated areas and arid regions of the world was once treated as a joke more appropriate to cartoons than real life.
But now it is being considered quite seriously by many nations, especially since scientists have warned that the human race will outgrow its fresh water supply faster than it runs out of food. Glaciers are a possible source of fresh water that has been overlooked until recently. Three-quarters of the Earth＇s fresh water supply is still tied up in glacial ice, a reservoir of untapped fresh water so immense that it could sustain all the rivers of the world for 1,000 years.
Floating on the oceans every year are 7,659 trillion metric tons of ice encased in 10000 icebergs that break away from the polar ice caps, more than ninety percent of them from Antarctica. Huge glaciers that stretch over the shallow continental shelf give birth to icebergs throughout the year. Icebergs are not like sea ice, which is formed when the sea itself freezes, rather, they are formed entirely on land, breaking off when glaciers spread over the sea. As they drift away from the polar region, icebergs sometimes move mysteriously in a direction opposite to the wind, pulled by subsurface currents. Because they melt more slowly than smaller pieces of ice, icebergs have been known to drift as far north as 35 degrees south of the equator in the Atlantic Ocean.
To corral them and steer them to parts of the world where they are needed would not be too difficult. The difficulty arises in other technical matters, such as the prevention of rapid melting in warmer climates and the funneling of fresh water to shore in great volume. But even if the icebergs lost half of their volume in towing, the water they could provide would be far cheaper than that produced by desalinization, or removing salt from water.

It is generally believed that there is a good supply of fresh water. But to our disappointment, the fact is just the opposite.
As we can see, the world population is growing rapidly day by day. So enough fresh water is needed to feed such a big population. Whats more, with the development of industry, factories and vehicles produce poisonous gases or wastes, which consequently results in the pollution of water. Though fresh, a good amount of it can no longer be used. Only quite limited fresh water resource is available to human beings. So its high time for us human beings to take quick action to protect water resource. Stop pollution and save water, otherwise, we cannot survive on the earth. With fresh water, the world will be prosperous.

It is widely believed that froth water will never be used up because we can get itfromrain, rivers and wells. As a matter of fact, such belief is wrong and possibly dan gerous.
Scientists have revealed that despite the fact that the 70% of the earths surface is covereclwith water, a little part of it is fresh water. Ninety percent of fresh water is stored in the Antarctic zone and cannot be directly used.
Fresh water is used to feed people and propel machines. With the increasing number of the population and factories, the amount of fresh water in use is also growing rapidly. It is estimated that if such growth is not controlled, the fresh water will be used up by the next century. Another dangerous factor is that the water pollution including industrial wastes and poisonous gases which eventually blacken rivers and form acid rains.
We still have time if we act just now. We must tell all the othem the importance of fresh water and the danger we are facing. We can control the number of factories and the wastes they produce. We can also develop new ways to use our limited fresh water more economieally.
