China has the largest population in the world.Now chinese population has reached 1.3 Billion,and 56% people live in the countryside.That is about 728 million,it's a huge number.Some parents in less developed areas still prefer boys to girls,and that is the main reason of the imbalance between male and female.Because of the poor economic situation,not all Chinese families can offer their chidren a good education.And more children have to leave in countryside to became famers that they don't want to be,that is not a comfortable life .I think a comfortable life should be like this:one can do job that he likes,and the job can offer him a good pay.so man can enjoy the job and enjoy the life.Obviously,we need to control the population
to make our lives more comfortable.
