Crisis and Opportunity Essay Example for Free

Crisis and Opportunity Essay1) IntroductionNowadays, we have select forthd our own world of technology. devisal and efficiency be catered through it. Yet, the earth, the native world, seems to rebel against such artificial world, by sending signals of natural crises to us. In this project, we atomic number 18 going to talk fitting about How heap benefit from piss Crisis surrounding the ascendant Crisis and Opportunity. The irrigate crisis is branched out as two sections, namely body of body of weewee shortage and body of urine pollution.The union of water supply in the world is stable it just deepens its physical forms. Nonetheless, the problem of water shortages still exists. In fact, what we lack is percipient water. With rapid advancing of human activities and technology, and unfavorable natural features like uneven scattering of rivers, the water crisis is growingly affecting our lives negatively and takes them at risk. water is polluted by increasing human activities. industrial wastes which include heavy metals like mercury and lead, harmful to living things, argon illeg bothy dumped into water get-gos cloaca is directly deposited into rivers, which normally is a source of clean water. Ultimately, global warming, was elicited by human too, depletes clean water. With changing of climates, some(a) countries present more than floods which pollute clean water while different countries cause more droughts which stir massive drying out of clean water.Now, we sound worrying about the crisis because water controls our lives tightly as we could not survive without it. On the other hand, people are developing more and more solutions. By approaching the problem optimistically, this ought to turn this crisis into an opportunity so that we and the world digest proceed sustainably. Scientists from all just about the world have come up with ideas to enlighten the problem piecemeal.2) Literature ReviewWe apply secondary research i n this paper as in that respect is simply no way for us to conduct our own research on water crisis. We mainly consulted online websites and hire some online books. We also read articles from credible magazines such as National Geographic There is also a website called Global irrigate Intelligence which is a Market-Leading website for the analysis of International water industry.From these sources, we mainly found out that water is truly limited around the world and there are people dying from consuming polluted water or simply dehydration. We also found out that the water crisis brought out some new technologies that changed the water pattern of the world.Have you ever thought of turning water from your basin into drinking water? roughly people may think that it is impossible, or even a disaster. However, in Singapore, scientists have developed some methods, which give the bounce change waste water into pure water. The re utilize water is called the invigorated peeing.How t o purify used water? Used water is collected from residence, companies, and schools, and then it is purified by three steps. First, it undergoes microfiltration. Large particles rout out be filtered away in this step. Afterwards, it undergoes reverse osmosis. Differentially-permeable membranes are used in reverse osmosis. These membranes contain tiny holes, which roll in the hay only allow water molecules to pass through, so contaminated substances, such as viruses, bacteria can be removed. Lastly, ultraviolet light is used as a back-up to ensure the remaining micro-organisms were completely killed. This makes youthful Water.On the other hand, some people might worry that sensitive Water was unclean, and thusly may affect the health of citizens. However, research conducted, as shown in figure 1 and 2, the level of primitive substance and amount of bacteria in New Water was much lower than the local man-made lake water. Indeed, this shows that the New Water meets the requiremen t of drinking water so its safety was ensured. Compare to the other sources of water, New Water is even cleaner. Therefore, it was awarded many an(prenominal) global water awards among these years, and this can surely tackle the problem of water shortage without polluting.There is another way to tackle water shortage and pollution. Do you know how sailors reach fresh water when they are on a voyage? They obtain fresh water by changing sea water into drinking water. This method is called desalination.Sea water accounts for 97% of the worlds water resource. Only the remaining 3% is consumable for humans. In some countries like Saudi Arabia, there is water shortage. They only have a small amount of consumable fresh water. However, they have a large supply of sea water. However the salinity of sea water is four times high than our body fluids. When we drink salt water, water molecules in our cells forget move out of the cell overdue to osmosis. This net transfer of water may cause our cells to shrink, which may lead to dehydration, and death in somber situations. So how can this modern technology suspensor us to turn this crisis into another opportunity?desalination refers to the removal of salt and other minerals of saline water to make it consumable. It has become increasingly popular in recent years due to enhancement in technology. There are two methods for desalination.The most commonalty type is work by reverse osmosis, which is based on osmosis- the movement of substances from a lower immersion to a higher c oncentration. It is a membrane-technology filtration and removes salt and minerals by pressurizing the sea water, forcing them to move through the discriminating membrane. The selective membrane has pores that allow only water particle to pass through, so that salt molecules and other pollutants are trapped behind the membrane. The by-product produced in the process is salt. It piddles an economic opportunity.The process in a desalination in dustrial plantThermal distillation is another way of desalination other than reverse osmosis. It is known as the multi-stage flash distillation. It distillates water by flashing a portion of water into steam in aggregate stages and then condense them into portable water.Where do we find desalination plant? In Hong Kong, the Water Supplies department has two desalination plants which use reverse osmosis. The first one is fit(p) in Ap Lei Chau and the other one located in Tuen Mun. The government is also planning to build another desalination plant in Tseung Kwan O. There are 100 countries around the world which uses this technology. Saudi Arabia accounts for 25% of the worlds desalination output, with over 2000 desalination plants around the country.A desalination plant in Saudi Arabia. away from the problem of water pollution and water shortage, water crisis itself can also be an opportunity, if we look at it from another perspective. It can urge on global awareness and promote multinational cooperation. Thus it drives globalization.Water crisis is a global issue. It cannot be clear upd by only the cooperation of a few countries full cooperation from countries all around the world is required. Therefore, some international cooperation was established in order to friend countries joining hands to solve water crisis. One of the examples is the origination Water Council.The World Water Council organizes the World Water Forum once every three years. In the forum, representatives from different countries join together and come up with some solutions to solve the water crisis. It includes signing of protocols, reducing pollutants in order to help geographic areas that are facing an immediate water shortage. This can not only help to solve the water crisis, but also create peace among countries.3) Discussion and AnalysisWhat are the benefits of use New Water sort of of local rootage water? First, it can solve the problem of water shortage. In Singapore, there is not enough water because there are only a few rivers running through this small country, but it is thickly populated. Reused water is using the same amount of water many times, so we can have illimitable water source without worrying being used up. Moreover, using New Water can help protecting the environment. Waste water cause water pollution, which can contaminate fresh water source by using New Water, water can be reused and it will not cause any further pollution.This is beneficial to the environment. Furthermore, New Water can boost tourism. In Singapore, the NEw Water visitors centre is a new attraction. It attracts tourists to visit as it provides opportunities for them to explore Science and learn more about water. Last but not least, New Water can help Singapore to make money, as it can sell this technology to other countries. Some countries, such as, China and Europe has already started using New Water instead, as it is purer than local reservoir water. In concl usion, New Water is alternate solution, which can change water pollution and shortage into a profitable opportunity.Now, let us move on to desalination. Some people think that although desalination may seem to be a solution to our circulating(prenominal) water crisis, it has certain potential implications that cause harm to our environment. Fossil fuels or atomic power are used in the majority of desalination plants. The burning of fossil fuels releases a large amount of ascorbic acid dioxide into the air. The increase in this disastrous greenhouse gas consequently makes global warming worse. Alternatively, but still, nuclear power is dangerous. The radiation leakage in Japan had spread concerns all over the world. Radiation is carcinogenic. muckle living near the nuclear power plant had to be relocated. It even made Japanese sea nourishment un-consumable. Besides, the food chain is affected since water and soil is polluted by radiation. Furthermore, membrane-technology is expen sive.The production cost of water per molar concentration cube is HK$7.8- HK$8.4. However, the advantages of desalination outweights its cost because it can make water available to areas that have a meagerly supply of fresh water. Why Saudi Arabia needs a lot of desalination plant? It is because it is located in a place where there is short supply of water. With desalination, they can change sea water into fresh water. It provides a reliable and sufficient supply of water to the growing communities, which reduces the crisis of water shortage. More people will have a steady supply of water and lives will be saved. People will no longer die from the lackage of water. The costs of human lives are much more important than the costs of desalination.The cost of desalination is only short-term and it can be solved by using renewable energy instead, such as solar energy and wind power. Also, the cost of desalination will be lowered once it is developed and widely used around the world. To sum up, desalination is another powerful way to change water crisis into an opportunity.A coin has two sides. Water crisis does not only bring disadvantages, but it is also an opportunity for countries to join together and solve this global issue. This can improve international relationships and bring peace to countries.On the one hand, some people may argue that water crisis would not bring any peace to countries, but instead it brings conflicts and chaos. Some research show that as water crisis is getting more and more serious, water source becomes a weapon, and it may be a curse to other countries. Therefore, if one country is located at the upper course, while the other is located at the lower course, the one at the upper course can control the flow of water.However, the establishments of international organizations help to solve this problem together by promoting the saving of water supply and improvement of technology. This can create communication channels and may help to maintain peace in certain countries. For example, the 6th Water Forum held in Marseille, from 12 to 17 March 2012 was a great success. Participants from over 145 countries join this event. They discuss global water problems together. Through debates and in-depth dialogue, they were able to know more about water crisis and many stakeholders commit that they would try their best to conserve water in order to help the needy. This shows that water crisis can raise global awareness and promote international cooperation.(+ but piecemeal and suggestion) (favourable risk and insight)4) ConclusionThe water crisis does not have to be devastating. Flipside, there are advantages of it on bringing opportunities to communities, the world and to us. In face with the same problem, people unite and untangle the cluttered yarn of puzzle, mystery and problems. Because of the water crisis, people start organizing Water Forums so that opinions all around are synthesized, analyzed and become a grand solu tion. working scientists, assisting each other and aiming at the target, invented ways like the New water and desalination of water.Even the darkest darkness will end. And the sun will rise. There is always a solution to a problem. However, we could not just rely on the technology to solve this problem but we should also help conserving water and raise the global awareness. To solve the problem entirely we must start from its roots. Take a shower instead of a bath. Dont leave the water running when you are brushing your teeth. Switch glowering any dripping taps. This will also decrease your electricity bill and help to build a greener environment where water is plentiful. If we still consume water at a stage like this, we are exploiting resources from our next generations, which doesnt make the planet sustainable. With the cooperation of everybody, we strongly believe that water crisis will definitely change into an opportunity and the world would be a better place to live in.5) Reference and AppendicesAsias Water Crisisand Opportunity (No.2 2011) Solutions http//solutions.bv.com/asias-water-crisis-and-opportunity/Peak Water Crisis or Opportunity?
