China is one of 13 water shortage countries around the world, it’s per capita water is only a quarter of the world's average rate, ranking NO.110 among all 149 countries around the world. Currently, among more than 670 cities, there are 500 cities has the water scarcity problem, in which about 130 cities are seriously lack of water. Overall cities have 6 billion square meters per year shortage of water , in which the daily water volume is more than 16.05 million square meters, and increasing all the time. In fact, not all the cities have no water, they need water that clean and drinkable. According to the National Water Resources research about the annual emission of polluted and waste water around the six major river basins, the survey estimated that the current national annual emissions of sewage now reached 56.66 trillion square meters high, of which more than 80% of untreated sewage are directly into the waters, more than 90% of urban water are seriously polluted . All 40% of cities’ undrinkable are drinkable water being polluted , for the rive flowing through the city, in which 78% is not suitable for the drinking Source and 52% of the drinkable under-groundwater is contaminated, over 70% of people in China are using substandard tap water. Therefore, the majority reason of urban water shortage is the water pollution which means the inefficient waste-water treatment
China economy has been falling for many years. Part of this downfall is lack of clean water. You know this, but know one in this world can’t live without water ,so that means water is very important. Climate change, Industrialization, and Government policy all contribute to the chinese water crisis. Of these, the biggest driver is the government policy. The government in China has a strict policy that does not allow the people to have water because China is not using enough money for their water.
It is true that there are factors contributing to China’s water scarcity, such as a bad government policy. However, the three biggest causes of China’s water-scarcity crisis are population growth, global warming, and especially industry. It is important because
The industrialization of Canada is severely affecting the nations lakes, streams, and rivers. If something is not done to improve the situation it is going to have some severe environmental problems in its future. The following essay will be looking at the factors that cause pollution, and the effect that pollution has on the environment of Canada. It will also explore some of the methods used to treat and clean-up wastewater, and oil spills.
'Water pollution is any chemical, physical or biological change in the quality of water that has a harmful effect on any living thing that drinks or uses or lives(in) it. ' (Azeem 1). In Canada, most people live in the southern part along with many agricultural and industrial activities causing the worst cases of water pollution. Water pollution is caused by population growth and industrialization, but can be prevented if proper controls are taken into consideration to help reduce the discharge of waste materials. Water pollution has been a huge disadvantaging concern for humans as well as wildlife for over many decades, but can actually be prevented if attempted. Preventing waste materials from being dumped into lakes and rivers, controlling
Most of water consumed in China is not rationally used. The cause which intensifies the water shortage in China is water inefficient use. For instance, 65%-70% of Chinese water usage is spent on agricultural needs, but more than half of this amount evaporates percolates and loses (Roberts 2009). Besides, majority of another 20%-25% which is occupied by China’s industry is not recycled (Brown 2008a, 16; Roberts 2009). Obviously, improving water distribution technologies and management quality can be one of the options to reduce the water scarcity in China. There are many different methods of improving the water distribution efficiency. Firstly, irrigation technologies should be improved. Farmers in China may use drip and shrink irrigation methods instead of traditional “surface” ones such as furrow and flood irrigation. Drip irrigation method is used mostly in arid and semi-arid zones and it increases the efficiency of irrigation by transporting the water directly to the roots of irrigated plant. The emitters sprinkle the soil under the roots with water which is introduced to the plant by pipes, diminishing water evaporation, deep percolation and leak. In contrast, fur...
Due to industrial waste ,domestic wastes and agriculture wastes entering into water source, Chinese government reporting that nearly 60 percent of China’s groundwater is polluted. It also leads the decrease in water quality. A large amount of water cannot be used and thus foster the water scarcity problem in China.
More than $31 billion worth of food is wasted every year in Canada and when energy, water and other resource costs are factored in the true cost could be up to as much as $107 Billion each year according to a report published by Value Chain Management International, a consulting firm, which suggests that millions of kilograms of food is wasted every year in Canadian homes, restarants, & grocery stores. This finding shows a 15 % increase from their findings four years ago when the cost was $27 Billion,in 2010. They also go on to say that this is 2% of Canada s GDP and larger than the total economic output of the poorest 29 countries on the planet.
In Canada, all three levels of government (federal, provincial/territorial, and municipal) have roles and responsibilities with respect to fresh water management. The...
Mexico is high-urbanized country. Almost 78% of its citizens live in cities (Castro and Heller 2009). That is why citizens of urban areas suffer the most from the appreciable water shortage. The situation with water supply in urban areas is critical. As an example, Mexico City, with population about 20 million people, faces quite serious scarcity of water. It obtains water from 3 main basins, all of them are overexploited (UNESCO 2006). The solution of the government to this problem was to pump water from the aquifers. However, these palliative actions of the government have not solved the problem, three aquifers from which city gets water are overused (UNESCO 2006).
The human race needs three things to survive; air to breathe, food to eat, and water to drink. A large majority of the public thinks these resources are infinite and plentiful. What they fail to realize is that they are not infinite, air can become polluted, food can carry pesticides, and water can transmit diseases very easily. In order to keep these necessities safe, many companies are taking the initiative by trying to cut down on pollution and stop using harmful pesticides. Water, however is not getting enough attention, especially in urban areas. Framework exists for these urban areas to be able to have successful water management, but some countries cannot afford these ideas or simply do not want
HOW TO REDUCE WATER POLLUTION My research question is how do we reduce water pollution in Canada but first I will explain what water Pollution is and how it is affecting us. Water pollution occurs is when our surrounding bodies of water become Contaminated either by sewage being poured into the water as a way of disposing of it easily, or the daily oil spills that occur and destroy ocean floors contaminate our water although we can clean up these oil spills we unfortunately cannot do it before all damage has been done, the constant dump trucks pouring garbage into the oceans and Atmospheric deposition when water particles mix with carbon dioxide sulphur dioxide and nitrogen dioxide and they create a very unconsecrated acid and when it rains, snows
The main sources of water in Bhutan are natural spring water, natural rivers/streams and deep groundwater and water quality is reported as first class conditions expect at localized urban areas. Four major river sinks are Amochhu, Wangchhu, Punatsangchhu and Manas. The main activities that cause water pollutions in Bhutan are ongoing development and human actives such as urbanization, rapid growth of population, more hydro electric projects construction and other infrastructure development and industization activities which produce huge amount of waste leading contamination of water bodies in the country degrading quality of safe drinking water of the nation. Human waste and solid waste dumping in the rivers and urbanization waste water.
Developed countries struggle with managing water consumption. Our high demand in agriculture, industry, and domestic use further complicates this issue. With increasing urbanization and extravagant changes in lifestyle, our use and wasting of water will only increase. As of this year, nearly 1.1 billion people live without clean drinking water and 2.6 billion live without adequate water sanitation. The McDonald's down the street, however, will sell you a 1/3 pounder burger for only 150 gallons. Changes in lifestyle can easily reduce this number and help not only save water, but money as well. Currently, with our diminishing water supply, one of the main goals of humanitarian organizations is ensuring that everyone has t...
Water scarcity is harmful to human life because when water is poorly managed throughout the world, those who need water are deprived of nutrients they truly need, causing them to die. This eventually affects the global population. Therefore, many experts have proposed several solutions such as the LifeSaver Bottle, TrojanUVPhox treatment system, and Waste Water Recycling. The problem of water scarcity has increasingly spread throughout the world as of yet, The UN reports that within the next half- century up to 7 billion people in 60 countries which is more than the whole present population will face water scarcity (Sawin “Water Scarcity could Overwhelm the Next Generation”). As well, the demand for freshwater has tripled over the past 50 years, and is continuing to rise as a result of population growth and economic development.
Less than 1% of the water supply on earth can be used as drinking water.
