㈠ 水资源英语作文
水是生命之源，生命之本，人类的健康离不开水。人可以几天不进食，但不可以几天不喝水。而现在，全球有20亿人口正处于严重缺水状况！！水的危机，已经向人类敲响了警钟！
中国的水资源虽然比较丰富，但是大部分水都是海水,而海水是咸的,是不能直接饮用的;再加上大部分淡水都分布在寒冷的南、北两极和终年积雪的高山上,这样淡水资源就所剩无几了。而且分布不均，东多西少，南多北少，缺水的地方很多。
小时候我想，自来水龙头里的水不是一直流个不停吗？爸爸妈妈常常给我讲哪些地方最近又闹干旱了，不要说种庄稼，就是人喝的水都难以保证。我总觉得不可想象，水不是地球上最多的东西吗？大江、大河、大湖、大海不是有那么多吗？怎么会缺水呢！
后来，我慢慢长大，也慢慢弄明白：水是地球上所有生命的源泉。地球上的总水量为18万亿亿升。这个数量似乎能满足全球人口对水资源的需求，但实际情况并不令人乐观。现存水储备的99%是不宜人类利用的海水和极地冰，其余1%还大都在800米以下的地层，人们生存所依赖的河流湖泊的水仅占总量的 0.01%。世界上已有18个国家的人均可再生水资源拥有量不到1000立方米。据世界资源研究所的一项报告表明，世界上有34亿人口平均每年只能得到 50升水，这标志着人类正面临着淡水短缺的危机。
这一严峻形势并没有引起人们足够的重视，人们赖以生存的河流、湖泊正面临着越来越多污染的威胁。只有杜绝污染物进入河流湖泊，或者减少其数量，河流湖泊中原有的污染物才会随水流走、稀释，逐渐减少。因此，防治河流湖泊污染的最根本的方法就是控制污染源。我们知道，河流湖泊污染来源是工业废水和城乡生活污水。国家制定了一系列保护水资源的法律法规，对废水排放等各方面，都作了严格的限制和规定。
如果我们不珍惜水资源的话，将来地球上流下的最后一滴水是自己的眼泪。

㈦ 求一篇水资源是否取之不尽用之不竭的大学英语作文
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.
