㈠ 水資源英語作文
水是生命之源，生命之本，人類的健康離不開水。人可以幾天不進食，但不可以幾天不喝水。而現在，全球有20億人口正處於嚴重缺水狀況！！水的危機，已經向人類敲響了警鍾！
中國的水資源雖然比較豐富，但是大部分水都是海水,而海水是鹹的,是不能直接飲用的;再加上大部分淡水都分布在寒冷的南、北兩極和終年積雪的高山上,這樣淡水資源就所剩無幾了。而且分布不均，東多西少，南多北少，缺水的地方很多。
小時候我想，自來水龍頭里的水不是一直流個不停嗎？爸爸媽媽常常給我講哪些地方最近又鬧乾旱了，不要說種莊稼，就是人喝的水都難以保證。我總覺得不可想像，水不是地球上最多的東西嗎？大江、大河、大湖、大海不是有那麼多嗎？怎麼會缺水呢！
後來，我慢慢長大，也慢慢弄明白：水是地球上所有生命的源泉。地球上的總水量為18萬億億升。這個數量似乎能滿足全球人口對水資源的需求，但實際情況並不令人樂觀。現存水儲備的99%是不宜人類利用的海水和極地冰，其餘1%還大都在800米以下的地層，人們生存所依賴的河流湖泊的水僅占總量的 0.01%。世界上已有18個國家的人均可再生水資源擁有量不到1000立方米。據世界資源研究所的一項報告表明，世界上有34億人口平均每年只能得到 50升水，這標志著人類正面臨著淡水短缺的危機。
這一嚴峻形勢並沒有引起人們足夠的重視，人們賴以生存的河流、湖泊正面臨著越來越多污染的威脅。只有杜絕污染物進入河流湖泊，或者減少其數量，河流湖泊中原有的污染物才會隨水流走、稀釋，逐漸減少。因此，防治河流湖泊污染的最根本的方法就是控制污染源。我們知道，河流湖泊污染來源是工業廢水和城鄉生活污水。國家制定了一系列保護水資源的法律法規，對廢水排放等各方面，都作了嚴格的限制和規定。
如果我們不珍惜水資源的話，將來地球上流下的最後一滴水是自己的眼淚。

㈦ 求一篇水資源是否取之不盡用之不竭的大學英語作文
To save water in the film is not a fool?
Said film of water on earth was not spent, and tell people to save water, rivers or the Earth will become arid. But the water go? Based on material conservation theorem, it is in any case water, how much water, through a variety of cycle (natural cycle and artificial cycle), water or in the face of the earth, or so much. Of course, I said that "water is not used there will be no rivers and the earth will not change people's water and drought", is not to say that "water can be polluted to drink, the earth's environment can be destroyed the residence." But even if the water was contaminated, but to live with little water to the natural cycle of purification,
Pollution of water and damage to the environment are large instrial and chemical instries, the water was contaminated after purification treatment can be discharged through the artificial seawater net (short), and only the high cost of water. Water is a highly profitable monopoly instries, the more money with much more, from two years ago, a ton of money to rise to 3 present a ton of money, like so many people not to use it? Even if the money will rise to 6 is also a ton of people do not like to use it? 1-5 million of goods drinking water / 500 ml It is also not acceptable? Waste (use) of water is not contaminated, even open their own day-long water hose go to buy 100 tons of water or a
100 bottles of drinking water drained commodities, it is a waste of their money, water continues to flow in the face of the earth, fresh water or fresh water, or less.
Who can say where the earth was no water to drink? Earth will never have that day. Earth's greatest resource is water. Long-term aircraft carrier sailing in the ocean, but it will not take a lot of fresh water from the shore sailing, a Nimitz-class aircraft carrier the amount of fresh water daily purifying enough of New York City, half a day water consumption. Now what can not be separated from economic and social money, each person will be the volume of each enterprise's ability to spend money on their own, much money to spend, less money, spend less, save for those who can not afford to go in terms of. To spend money on the community to contribute money to the prosperity of the economy and increase employment, renewable sources of wealth. Conservation is not always right, as the current economic recession,
Policy of expanding domestic demand to stimulate consumption. Not an excuse to consume resources, resources are used to people, not just the water, people used to wear to see the food and drink to be playing live in the consumption of resources, a few dollars to feed people a meal, a few hundred thousands of thousands of dollars are also eat a meal, over a hundred dollars to rent a room to live, tens of millions of millions of the building is occupied, and several millions of yuan a car is a car, dozens of dollars to buy a set of clothes , also hundreds of thousands of thousands of dollars to buy a set of clothing, Can we say that people with high consumption to waste? Not. They bring a lot of growth and creating a lot of jobs, increased the state tax
Admission, they are in the promotion of social progress. To protect water resources from pollution problems to solve rather than to proceed from the start to save water, little by little to save millions of people a month are not enough water in a large steel water a day, so water conservation is not the protection of water resources. It is to avoid pollution problems. That the use of fresh water will become salty after it is ignorance, because the Earth are no fresh water, fresh water from the (ocean) water evaporation of water formedfrost snowessence ice from rain, ice and airfrost snow rain water essence it is not salty, as long as there isfrost snow rain water ice and air in essence there will be fresh water, ice and rainfrost snow
Undine the air is always some gas. Fresh water (including underground fresh water) is the main source of rain and melting of ice (hail) Xue, China's average annual precipitation of 600 mm, 300 mm have been considered the absorption and evaporation of the surface, there are 300-mm inflow of rivers and lakes, China covers an area of 9,600,000 square kilometers, population 1.3 billion annually to our God of fresh water per capita are: 0.3/1300000000 = 9600000000000 * 2215 cubic meters, the amount of water can be reused several times over a few times or more, so China does not lack of water.
"Rolling rolling east to the river," "rivers to the sea", "Dajiang gone," we have heard these words many times, This shows that the flow of water is never and will not leave the people to stop, you used and unused, rough moment will keep the river flows into the sea. The annual flood period, the volume of river water into the sea Can we say that the water people waste it? At that time, people also pray to water less. Drought in some areas since ancient times is nothing to do with water, let alone in the universe, the Earth's movement in sports, some of the areas of water will become more arid, drought in some areas will become a flood plain, as the Yellow River flow, sea level rise,
Sichuan lake side cover, as the rationale for this is easy. To resolve the shortage of water resources in arid regions is the West South-North Water Transfer East lose water in dry areas and the construction of more large reservoirs. Those who advocate the use of water were not there would be no ignorance in order to raise the price of water and the fool.
