The Global Water Crisis(全球用水危机)
The Global Water CrisisAs we all know that there are more and more environmental events in our world . However , one of the most serious problems is the global water crisis.Water is vital to the survival of all known life forms. Water crisis is the state of the world’s water resources in relation to human demand. Global scarcity of usable water and water pollution are the major aspects of water crisis. A lot of people around the world do not have access to clean potable water, and the numbers are growing.Around the world, 1.1 billion people are living without clean drinking water; another 2.6 billion people do not have proper sanitation, this results to death all over due to water borne diseases.We see water all around us, yes 71% of the Earth’s s urface is covered with water, but we have to understand that only a percentage of that is fit for consumption. The large water composition of our planet doesn’t mean that we have an infinite supply of useable water. By simple observation, a huge portion of the Earth’s water is salty, or locked up in ice and glaciers.The Earth although abundant with water has a limited supply of fresh water. Oceans may be deemed as available water but the energy needed to convert salt water to fresh water is restrictive, only a fraction of fresh water can be derived from desalination, although newer technology is helping reverse the ratio. Water which is fit for consumption constitutes only a small percentage of all the water resources, and the sad thing is that it is diminishing because of contamination and pollution.Inadequate supply of safe water and lack of sanitation accounts for the rising number of child deaths because of diarrhea. Poor supply of water for sanitation results to deaths affecting children most especially in underdeveloped countries, such deaths are considered preventable if only we can find a way how to distribute clean water properly.Vegetation and livestock are all dependent on freshwater resources. This is our major food source and if it is threatened, it will challenge our survival as well. Overdrafting of groundwater causes decrease in agricultural yields. Low agricultural yields and deaths in livestock are direct results of water pollution. Water pollution and overuse ofunderground water resources truly harms biodiversity causing imbalance in natureArmed conflicts arise over meager water resources resulting in displaced community due to this conflict. Regional conflicts arise in roughly 260 different river systems around the world. Existing international rules grants water rights among countries but still conflicts due to regional tensions on water supply are becoming a fight for survival, and warfare is inevitable. It is not just the scarcity of water that is causing death but the conflict that goes with it.The demand for fresh, safe water increases over the course of time. Everybody must take their part in conserving water. The global water crisis will never go away if we don’t take an active part in providing our very own share. Each of us must think twice every time we turn that faucet.。

解决淡水危机英语作文高中
Water is the source of life, and without it, our planet would be barren and lifeless. However, the availability of fresh water is increasingly under threat due to various factors such as climate change, pollution, and overextraction. As a high school student who is deeply concerned about the environment, I have been actively involved in understanding and addressing the freshwater crisis.Growing up in a coastal town, I have always been surrounded by water, but it was not until I took part in a school project on water conservation that I realized the gravity of the freshwater crisis. Our project involved researching the sources of water in our town, the methods of water treatment, and the ways in which water is consumed and wasted. What I discovered was shocking: a significant portion of our water supply was being wasted due to leaks in the distribution system and inefficient use by households and industries.One of the most eyeopening experiences for me was visiting the local water treatment plant. I learned about the complex process of treating water to make it safe for consumption. The plant manager explained how climate change has led to unpredictable rainfall patterns, causing water shortages during dry seasons and floods during the wet seasons. This has put immense pressure on the water treatment facilities, as they have to cope with both scarcity and excess.To tackle the freshwater crisis, I believe that a multipronged approach is necessary. Firstly, we need to improve water infrastructure to reduce leakage and wastage. This could involve upgrading old pipes, installingwater meters, and promoting the use of waterefficient appliances. In our town, the local government has started a program to replace old pipes and educate the public about the importance of water conservation.Secondly, we need to promote sustainable water use in agriculture, which accounts for a significant portion of water consumption. This could involve adopting watersaving irrigation methods, such as drip irrigation, and promoting the cultivation of droughtresistant crops. I was fortunate to visit a farm that uses these techniques, and I was amazed by the difference it made in water usage and crop yield.Thirdly, we need to raise awareness about the importance of water conservation. This could involve educational campaigns in schools, communities, and workplaces. As part of our school project, we organized a water conservation fair where we shared our findings and offered tips on saving water at home. The response from the community was overwhelmingly positive, and many people pledged to make changes in their daily habits.Moreover, we need to invest in research and development of new technologies for water treatment and conservation. For example, advancements in desalination technology could provide a viable solution for waterscarce regions. I am particularly interested in the potential of nanotechnology in water purification, which could make it more efficient and costeffective.Lastly, we need to address the issue of water pollution, which is asignificant threat to the availability of clean water. This could involve stricter regulations on industrial discharges, better waste management practices, and promoting the use of ecofriendly products. I have participated in beach cleanups and river conservation projects, which have given me a firsthand experience of the impact of pollution on our water bodies.In conclusion, the freshwater crisis is a complex and pressing issue that requires a concerted effort from individuals, communities, and governments. As a high school student, I have gained a deeper understanding of the challenges and potential solutions. I believe that by taking small steps in our daily lives and supporting larger initiatives, we can make a significant difference in preserving this precious resource for future generations.。

However, in recent times, the world is facing a serious crisis related to water resources.One of the mn reasons for the water crisis is the increasing population. With more people demanding water for various purposes such as drinking, agriculture, industry, and domestic use, the avlable water supply is being stretched. Additionally, rapid urbanization and industrialization have led to higher water consumption and pollution, further exacerbating the problem.Climate change is also having a significant impact on water resources. Changes in rnfall patterns, such as more intense storms and droughts, can disrupt the water cycle and affect the avlability of water. Rising temperatures are melting glaciers and snowpacks, which are a major source of freshwater in many regions.Poor water management practices are another contributing factor. Inadequate infrastructure for water collection, storage, and distribution can result in water losses through leakage and evaporation. Additionally, inefficient irrigation methods in agriculture waste a large amount of water.The consequences of the water crisis are far-reaching. Water shortages can lead to economic disruptions, as industries may struggle to operate without a sufficient supply of water. Agriculture, which is highly dependent on water, may suffer reduced yields and productivity. In many areas, access to clean drinking water bees a challenge, affecting the health and well-being of people.To address this crisis, several measures need to be taken. Governments and international organizations should invest in improving water infrastructure and promoting sustnable water management practices. This includes implementing efficient irrigation systems, conserving water through measures such as rnwater harvesting, and promoting recycling and reuse of water.Education and awareness campgns are also crucial. People need to be educated about the importance of water conservation and the need to adopt sustnable water use habits. Individuals can play a role reducing their water consumption at home, such as fixing leaky faucets and taking shorter showers.Collaboration and international cooperation are essential. Different countries and regions need to work together to share knowledge and resources to address the global water crisis. Transboundary water issues also require joint efforts for their management.In conclusion, the water resources crisis is a serious threat that requires urgent attention and action. By taking proactive measures to conserve and manage water resources, we can ensure the avlability of this vital resource for future generations and mitigate the negative impacts of the crisis. Only through collective efforts can we overe this challenge and safeguard the well-being of our planet and its inhabitants.。

The Water CrisisGreater efficiency in water use is needed to meet the growing demands of a changing world【A】Per capita 人均water usage has been on an upward trend for many years. As countries industrialise and their citizens become more prosperous, their individual water usage increases rapidly. Annual per capital water withdrawals取回in the USA, for example, are about 1,700 cubic meters立方公尺, four times the level in China and fifty times the level in Ethiopia. In the 21st century, the world’s limited suppl y of renewable fresh water is having to meet demands of both larger total population and increased per capital consumption. The only practicable ways to resolve this problem in the longer term are economic pricing in conjunction with结合conservation measures.水危机提高水利用率以满足不断增长的用水需求A 很多年来，人均用水量一直呈现上升的趋势。
随着国家工业化程度和居民生活水平的提高，个人用水量也随之急剧增加。
例如，美国的年人均取水量大约为1700立方米，相当于中国的4倍，相当于埃塞俄比亚的50倍。
在21世纪，有限的可更新淡水供应必须满足不断增长的总人口和不断增加的人均用水量的諝求。
从长远来看，解决这一矛盾唯一可行的方法是将征收水费和有效的水储存措施结合起来。
【B】Agriculture consumes about 70% of the world’s fresh water, so improvements in irrigation can make the greatest impact. At present, average efficiency in the use of irrigated water in agriculture may be as low as 50%. Simple changes could improve the rate substantially, though it is unrealistic to expect very high levels of water-use efficiency in many developing countries, faced as they are with a chronic lack of capital and a largely untrained rural workforce. After agriculture, industry is the second biggest user of water and, in terms of value added per liter used, is sixty times more productive than agriculture. However, some industrial processes use vast amounts of water. For example, production of 1 kg of aluminium铝might require 1,500 liters of water. Paper production too is often very water-intensive. Though new processes have greatly reduced consumption, there is still plenty of room for big savings in industrial uses of water.B 农业消耗了世界上大约70%的淡水，因此改进灌溉方式对节水的效果最为显著：目前，农业灌溉用水的平均使用率可能只是50%。
虽然在很多发展中国家，由于长期缺乏资金以及存在大量未经培训的农村劳动力，其灌溉用水的使用率达到很高的程度是不现实的，但是简单的改变可以充分提高水的使用率。
工业是紧随农业之后的第二大用水行业，就每升水的附加价值而言，工业的产出量是农业的60倍11然而，某些工业生产过程需要使用大量的水。
例如，生产1公斤铝需要使用1500升水。
纸张生产也是水密集型产业。
虽然一些新的加工工艺已经大大降低了用水量_，但是工业用水还是存在很大的节约空间。
【C】In rich countries, water consumption has gradually been slowed down by price increases and the use of modern technology and recycling. In the USA, industrial production has risen fourfold since 1950, while water consumption has fallen by more than a third. Japan and Germany have similarly improved their use of water in manufacturing processes. Japanese industry, for example, now recycles more than 75% of process water. However, industrial water consumption is continuing to increase sharply in developing countries. With domestic and agricultural demands also increasing, the capacity of water supply systems is under growing strain.C 在发达国家，由于水价的提高，现代技术的使用以及循环用水，用水量已经逐渐下降了。
在美国，1950年以后的工业产值增加了4倍，而用水量下降了超过1/3。
日本和德国在制造过程中也类似地改进了用水方式。
例如，日本工业循环使用超过75%的处理水。
然而，发展中国家的工业用水量一直在急剧增加。
随着家庭用水和农业用水需求的增加，水供给系统的容量面临着越来越大的压力。
【D】Many experts believe that the best way to counter this trend is to impose water charges based on the real cost of supplies. This would provide a powerful incentive for consumers to introduce water-saving processes and recycling. Few governments charge realistic prices for water, especially to farmers. Even in rich California, farmers get water for less than a tenth of the cost of supply. In many developing countries there is virtually no charge for irrigation water, while energy prices are heavily subsidised too (which means that farmers can afford to run water pumps day and night). Water, which was once regarded as a free gift from heaven, is becoming a commodity which must be bought and sold on the open market just like oil. In the oil industry, the price increases which list the market in the 1970s, coupled with concerns that supplies were running low, led to new energy conservation measures all over the world. It was realised that investing in new sources was a far more costly option than improving efficiency of use.八similar emphasis on conservation will be the best and cheapest option for bridging the gap between water supply and demand.D 许多专家认为应对这种趋势的最好方法是根据水供给的真正成本征收水费。
这会强烈地刺激消费者采用节水系统或者循环用水。
很少有政府对水收取实际的费用，尤其是对农民。
即使在富裕的加利福尼亚，农民的水价也不到供应成本的1/10。
在很多发展中国家，实际上对灌溉用水是不收费的，而且能源价格也大幅降低(这意味着农民可以日夜使用水泵），一度被认为是上天赐予的礼物，现在正逐渐成为一种和石油一样必须在开放市场上购买和销售的日用品D在石油行业，20世纪70年代轰动市场的石油价格攀升，以及人们担心供给量会较少，导致了在世界各地出现了很多节能新举措。
