A very important world problem is the growing population on the earth. The population of the world today is more than 7,400,000,000. 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 the rate of the growth. It is about 1.63 percent every year.
Every second, 4.2 babies are born in the world. Another baby! Another baby! Another baby! You can not 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. The rapid growth of population will make a big problem by the year 2025. There will be as many as 8.1 billion people on the earth! So this is one of the biggest problems that you are going to see in your life.
