How can sustainable development save urban areasINTRODUCTION: The population of people living in urban areas is increasing every year, especially in developing countries. “Urbanization” is a very popular word in almost everyone. NOW. However, many serious problems arise along with the development of urbanization. Let's take Europe's urban problems as an example. The successful process of urban areas leads to problems such as housing shortage, long commutes between residence and work, migration of people from the countryside to urban areas and traffic jams. We cannot ignore them, otherwise they will be much worse in the future. What can we do? It is widely accepted that sustainable development can successfully solve the problems caused by urbanization, such as lack of resources, high prices, food shortage and unemployment. Urbanization leads to a huge need for resources and causes their shortage. Urban production currently accounts for the majority of resource consumption and waste production worldwide” (WRI, 1996). Resources, including food resources, are limited and cannot be available forever, but none of us can live without sufficient resources. We must therefore use resources sustainably to meet the enormous needs of urban areas. The idea of ​​sustainable development encourages people to use resources scientifically and in multiple stages. In other words, getting the most out of resources. For example, some factories use a lot of water and at the same time produce a lot of polluted water. In the past, they usually discharged polluted water directly into rivers. In this way, a lot of water is polluted and can no longer be used. Sustainable development suggests cleaning polluted water...... middle of paper ......resources. It is clear that if there are too many people, we will consume too many resources in a short time. And, once the environment can no longer support such enormous needs, it constitutes a disaster for the global world. So far we can conclude that all problems caused by urbanization are not isolated. In fact, they are closely related to each other. Urbanization is an inevitable choice for human development since everyone aspires to a better life. Sustainable development is also an inevitable choice for humanity to solve the problems caused by urbanization. With the process of urbanization, the contradiction between man and nature is more and more obvious and serious. These problems not only limit the process of urbanization, but also harm humanity in the future. Perhaps we have no choice but to promote sustainable development. This is the best choice.
