The population problem may be the most serious challenge against human beings now. It is said that the population passed the six billion mark in the year 1999. And now there are about 6.465 billion in the world. There are more than 1.3 billion in China. Last year the USA gave its latest report on the problem of the world's growing population. The world's birth rate is higher than the death rate.
As the population continues to grow, we are facing more and more problems. Though we have good harvest year after year, millions of people are still in hunger. Lots of buses have been put into use, yet they still remain too crowded. Each year thousands of new buildings are built, but they still can't meet the needs of the people. Much money has been raised to set up one school after another, however, they seem too crowded to hold so many children. Maybe each person will have one half to one square meter of space to live in in the future. There will be hardly enough space for anyone else.
