　　The human race has experienced a consistent increase in population since the beginning of its history. Famine and disease have done little to offset this steady increase. Too many people are added annually to the population of the world. So both the causes of population increase and the results of having more people are worth careful study.

　　Culture evolution is the major factor responsible for population increase. Early in human development, people invented tools to hunt animals. Later they built shelters to protect themselves. Step by step, they made life easier. As a result, fewer died from natural forces, such as harsh climate and disease.

　　In the past, when population grew, there was unexplored territory to inhabit. But now, almost all the habitable land has been explored.From joozone.com.

　　The world‘s population may reach 8.7 billion in 2033. It is clear that world population is a serious issue that needs careful attention. Human beings are unique to solve problems through cultural evolution.Facing the world population explosion in the near future. We must carry out the birth control program in order to save the mankind and save the world.

　　Almost every country in the world faced the population problem.China has the largest population, so the one-child policy was necessay. In America, there were 2 billion people 20 years ago, now there were 3 billion. Some day they will have the same amount people as we had in china, will they apply our population control policy? Anyway we could be sure they will not critize our population policy at that time.

　　These steps are there to be taken, but there appear to be some countries that are not seriously trying at the moment. If we cannot achieve that we will certainly not control population.

　　That said, I don‘t feel pessimistic that we are going to run out of resources: we are becoming more efficient at producing food faster than the rate at which population is increasing. There is, however, a risk that we will wreck the environment so effectively that the world will no longer be an attractive place to live. That really would be a dismal outcome, to reach world population equilibrium only to find we‘d destroyed the natural environment in the process.

　　Now, the population question already the worldwide basis question, we must pay attention. in 2000 the world population achieved 6,000,000,000, because the population question has been in the world the most major problem overpopulation brings many questions, caused the developing country population to account for the world population 4/5, but China adopted the birth control policy to have the effect.

　　One day,god is talking about the population problem with goddess.

　　He says,"Millions of years ago,we invented people.At that time,the population wasn‘t a problem and it was not large.But now,the population is a serious problem.The is growing so quickly that the earth cann‘t afford the population.Goddess,can you see the east of chinese dragon----China.The population of China is very large.What should they do?"

　　Goddess says,"They should try their best to control the population.they had better take measures to control the population.Tere is a good e癫痫病好治疗吗xample that the government of China has taken ‘one child policy‘to control the population.I believe sooner or later,the population grows slowly."
