Answer 1

Today's world population growth compared to the population growth 100 years ago is a big, big difference. The population has doubled many, many times, and even right now the world's population is still skyrocketing. There are several reasons for this. There have been scientific advances in health and medicine. Governments are providing cleaner public drinking water and more sanitary waste removal. With this, people are less likely to get sick. Another reason for rapid population growth is agriculture. Scientists have created newer, better methods to increase the world's food supply, and to make it healthier. They have created method's to protect crops from harmful insects, and to raise crops with less water. This is called the Green Revolution.
