Question

A very important world problem is the growth of population on the earth. The population of the world today is more than 6. 5 billion. That is a great number and we know it quite well. The important thing is not how large the population of the world is now,but the rate of the growth. It is about 1.63 percent every year after the number of dead people has been taken away.

Look at the second hand of your watch. Every second four babies are born into the world. Another baby！Another baby！Another baby！You can't speak quickly enough to keep up with the birth rate.

The population is growing faster and faster. So it goes on,day after day. In one day,people have to find food for over 350,000 mouths more.

This great growth of population will make a big problem by the year 2020 ― there will be as many as 7 ， 000 ， 000 ， 000 people on the earth. So this is one of the biggest problems you are facing in your life.
