China has executed the birth control policy since 1970s'. Through these years the benefits of the birth control policy are taking place in China. One of the main benefits is that the policy helps China to protect its environment better. It is well known that desertification, industrial pollution and household garbage are all vital environmental issues. In fact, the essential cause of these problems is the increasing of population.
People need food to survive. To grow more crops and to raise more livestock, forests are being cut down and grasslands are degenerating. Desertification in northwest China becomes more serious day by day. Every spring, sand is blown up by wind and form sandstorms. Without the block of forests, sandstorms travel from northwest all the way to the east coast of China. People in this area suffer a lot from sandstorms. Furthermore, these sandstorms even indicate a kind of horrible change in climate.
The developments of industries are driven by the demand of marketing while the demand of marketing is the consumption of the population, so the increase of population stimulates all the industries including some nonstandard factories which participate a lot in the industrial pollution. The industrial waste endangers water, air and soil which are all colsely related to the survival of plants, animals and human beings.
Household garbage, which seems normal to us, is actually polluting China’s environment with an incredible quantity. In China, people use up 30 million disposable lunchboxes and 3 billion plastic bags per day. Perhaps people can still say that it is reasonable for a country with a population of 1.4 billion. However, it takes several years to decompose a disposable lunchbox naturally. More terribly, the environment needs hundreds of years to “digest” a plastic bag. By the day when a year 2008 plastic bag decomposes, probably the whole planet is already covered by plastic bags.
