As the natural environment is on the verge ofbreakdown, people are making every effort to save it. Some communities vigorously develop afforested zones, and some attempt to reduce the use of plastic bags. Although the two approaches are not ineffective since plants reduce pollutants and cleanse air, and non-degradable pollutants can be cut with the reduced use of plastic bags, there is a better way, which is to develop public transportation.

The effectiveness of afforestation is undeniable yet slow and limited. When tree roots hold soil firmly, floating dust, one of the major culprits responsible for the poor air quality ,is unlikely. In addition, trees with large leafs are particularly useful in improving air quality. Those palm-sized leafs absorb toxic gases and produce Oxygen. However, planting trees and building parks takes time. At least three to five years is needed for a tree to grow up and to become robust and prosperous to serve as theshield against air pollutants. In addition, the urban land is so scarce that not enough parks can be built. For example, it is often idealistic that cities like Beijing or Shanghai have as many parks as possible, and as a matter of fact, parks are sparsely located in such cities, and thus many residents have no easy access to them.

In terms of putting a cap on using plastic bags, this idea has a good intent but often fails. First, local shops can hardly stop providing plastic bags unless their customers stop asking. However, shoppers always need these bags to contain their groceries or other items. In addition, there is no proper alternative to plastic bags. The common alternatives, bags made of cardboard paper or of cloth,are actually less environmental friendly. Although they are degradable or more durable, they are manufactured at greater cost of the environment. Also, people dispose of paper bags carelessly and often reuse plastic bags. Therefore, the use of plastic bags should continue for realistic reasons.
