Population--my opinions

When I was in childhood, in china just had few cars on the street,fewer people than now, and also less busy traffic. However, because from I began my education, i always in the best schools in our cities, there are so many students in one class--at least 60! Therefore, we just had very little space for each person, sometimes it was hard to cross between desks......

Now, in china still have large population, we already use family plan to control, but because the population base in too large,so it is still a seriouly problem to the govement! However, now in my city and also some others ,some not very good schools need to face a problem---close! There are not enough students to them,because the birth rate is reducing a lot! Also, because the family plan just alow some parents have one baby, so some of them use some methods to know the gender of baby, then choose male. In addation,in China, the law about family plan now is allowing some couples have two babies---if these two people are the single in his and her family. However, because the fees of one baby is already expensive to them ,so almost of them still perfer to choose having one baby.As a result, in schools ,it is very hard to make banlance of male and female! One of my friends is a teacher now, she told me in her class have 45 kids now, 32boys and just 13 girls!

Family plan is really good to control growth of population but it has lots of problems! How we can get better banlance of them, i think the best way is educating people better! Tell them how the important of this problem,and tell them the right idea about how to face and deal with this seriosly problem!
We just have one earth ,just one world can live on,at least until now we do not find another one can instead of it! Therefore, we should pay much more attention about it, because the large population has lots of problems,such as food shortage,and bad environment, also not good quality of life!
