Global Shortage of Fresh Water
Many people believe that the world’s supply of fresh water will never be used up. They think that fresh water comes from such a variety of sources that it is always sufficient for use. Such an opinion leads to a shocking waste of water.
As a matter of fact, the earth is short of fresh water. Furthermore, with the rapid growth of the world population, the rising demand for water by industry, and the serious pollution of our surroundings, the world is facing the ganger of running out of fresh water. Actually, in some big cities, fresh water can not meet the daily needs.
Therefore, to find new ways to save water is an urgent task. First, we should pass strict laws to control any waste of water. Second, scientists must work even harder to purify sea water, and try to find substitute to reduce the use of fresh water.
全球淡水短缺
許多人認(rèn)為，世界上的淡水供應(yīng)將永遠(yuǎn)不會枯竭。他們認(rèn)為，新鮮的水來自于這樣的各種來源，它總是足夠的使用。這種觀點(diǎn)導(dǎo)致了一種令人震驚的浪費(fèi)水。
事實(shí)上，地球是缺乏淡水的。此外，隨著世界人口的快速增長，對水的需求不斷增加，以及嚴(yán)重的環(huán)境污染，世界面臨著枯竭的危險(xiǎn)淡水。其實(shí)，在一些大城市，淡水不能滿足日常需要。
因此，尋找新的方法來節(jié)約用水是一項(xiàng)緊迫的任務(wù)。首先，我們應(yīng)該通過嚴(yán)格的法律來控制水的浪費(fèi)。其次，科學(xué)家必須更加努力地去凈化海水，并設(shè)法尋找替代品來減少淡水的使用。
