The Population Explosion: Causes and Consequences by Carolyn Kinder Yale-New Haven Teachers Institute (2012)
Until recently, birth rates and death rates were about the same, keeping the population stable. People had many children, but a large number of them died before age five. During the Industrial Revolution, a period of history in Europe and North America where there were great advances in science and technology, the success in reducing death rates was attributable to several factors.
Food Production Distribution
The remarkable facts about the last 150 years has been the ability of farmers to increase food production geometrically in some places. Agricultural practices have improved in the United States in the last two

Sewage dumped into a public water supply could cause dis-ease throughout the community. With this understanding, the science of public health was born. Today, public health measures like waste treatment, water purifi-cation, vaccination, and nutritional education are well developed in MDCs
And finally, with the advent of new medicines, disease was less of a problem in MDCs because medical science has invented a whole range of new medicines with which to treat everything from infections to pneumonia. In many LDCs, new drugs and medicines are simply not available. 22
Progress in medical science has, therefore, had a great effect on the population of most nations of the world. Nearly everywhere death rates have fallen. At the same time, birth rates, at least in the LDCs, have remained high. This combination of high birth rates and low death rates have led to the population explosion in many countries throughout the world.
The end of the population explosion worldwide will be determined by how much countries invest in family planning efforts to lower fertility and slow down popula-tion growth.
Rapid human population growth has a variety of consequences. Population grows fastest in the world's poorest countries. High fertility rates have historically been strongly correlated with poverty,
