What is population explosion?
Three Main Causes of Population Explosion are listed here
CAUSES
People have concerns about surviving daily living, such as meeting basic needs: food, water, and housing. First, access to safe drinking water was related to the incidence of epidemic diseases such as cholera and child survival. Less than 50% of the population had access to safe drinking water before 1990. By 1990, access to safe drinking water had increased by 75 per cent. But between 1990 and 2000 the numbers of people without access to safe water are projected to increase. An increasing number of countries both developed and develop-ing are approaching the limits of sustainable water use based on their own re-newable resources.
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 centuries. Much of the world experienced agricultural success, especially in the last 50 years. Between 1950 and 1984, for example, the amount of grain harvested worldwide increased from 631 million tons to 1.65 billion tons. This represents a gain of 2.6 times at a time when the world population increased by only 1.9 times
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.
