英语大神快来!why is there an increasing number of Chinese ?student

question 1：
This problem of a rising world population is largely the result of improved medical skills,which have lowered the death rate and,at the same time,raised the birth rate by increasing live births and the number of babies who survive early childhood.There is a growing realization that food production cannot keep pace with these increases,the result of which is that in some countries people are already starving to death while many millions more suffer from malnutrition.This problem is further complicated by the fact that in places like America and Europe we obtain by trade and consume far more food and resources like oil than,say,the average Indian,thus leaving even less for the people in the underdeveloped areas to survive on.
question 2：
it' s my honor to be here to tell you something about the school life in America.Almost all the students go to school on foot or by bus.Hardly do they go to school by bike.Most of the students have luch at school,and they don't have afternoon naps after lunch.The school is over at 3 p.m.After class,students would like to play basketball,play football,swim or choose other kinds of activities to relax themselves.You can see the school life in America is very relaxing.
