Cities are often thought of as concrete jungles (混凝土丛林) that are polluted and overcrowded with people. They are, however, places where there is a great economic (经济的) chance, and that is the reason why people still pour into cities in the hope of having a better future for themselves and their families.

As more and more people live in cities, planners are looking for ways to change cities into better living spaces. The way this is done is by improving infrastructure (基础设施) while also creating more public spaces that are both beautiful and green. This can be hard to achieve, especially in cities where planning was done in no order.

Some cities have been created with the idea of a green city as the goal. One such city, Masdar City in the United Arab Emirates, is to become a model for other cities to follow. It is being declared as a truly green city that depends on renewable sources (可再生资源) such as solar energy to provide all of its energy needs. In addition, it will be a zero waste city where everything can be reused. Whether it will truly reach its goals remains to be seen, but it will also act as an experiment for environmentally-friendly ideas to be tested.

Cities that want to become greener and more habitable (宜居的) have to look at all ways of city life, and Masdar City is at least trying to do this. From the use of energy and dealing with waste to green public transportation, the lessons to be learned from such a huge project as Masdar city may just turn out to be valuable.
