One of the most important world problems is the growing population on the earth. The population of the world today

is more than 6,500,000,000. 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 is the speed of the growth. It's about 1.63% every year.

In order to give you some ideas of the birth rate, look at the second hand of your watch. Every second, four babies

are born in the world. Another baby! Another baby! Another baby! Another baby! You cannot speak quickly enough

to keep up with the birth rate. The population is growing faster and faster. In one day, people have to find food for over

350,000 mouths more.

This growing population will make a big problem by the year 2010-there will be as many as 7,000,000,000 people on

the earth! So this is one of the biggest problems that you are going to see in your life.
