Urbanization and sustainable developmentTang 1 IrisWe all know that the rate of urbanization is an index allowing the development of a country to be valued. However, although urbanization brings great comfort to some individuals, it also brings negative effects. Problems such as pollution, overpopulation and high unemployment arise during the process of urbanization and are difficult to solve. Faced with the chain of problems, a new development path – sustainable development – ​​was proposed. Just like its literal meaning, the word sustainability has something to do with continuity. It has been used since the 1980s and first appeared in UK legislation in 1993. Sustainable development can help solve some of the problem caused by urbanization, including environmental damage, overexploitation of resources and disasters natural. in other words, pollution. For example, water pollution is serious today. Factories continually released wastewater laden with toxic chemicals. Considering the goal of sustainable development, we can find some ideas to solve the problem. First, the sewage system should be improved during development so that drinking water can become purer. Moreover, rainwater can be separated from industrial and domestic water, it must pass through another system so that people can harness it more efficiently and correctly. Emissions of wastewater containing organophosphate pesticides should also be limited, as they heavily pollute water and harm not only fish and aquatic animals, but also people who use the polluted water. Air pollution caused by overurbanization is one of the most serious problems... middle of paper ... it's an event "just a coincidence because several small earthquakes occurred before the big one" (Zhang, 2008), but it proved that if we can predict dangers accurately, many losses can be avoided. Just like above, sustainable development helps a lot to deal with the problems caused by urbanization.References: 1.Anonymous.
