INTRODUCTION

What is Overpopulation?

Definition

Over-population is defined as the condition of having more people than can live on the earth in comfort, happiness and health and still leave the world a fit place for future generations.

Overpopulation A Fear

It took the entire history of humankind for the population to reach 1 billion around 1810. Just 120 years later, this doubled to 2 billion people (1930); then 4 billion in 1975 (45 years). The number of people in the world has risen from 4.4 billion people in 1980 to 7.6 billion as of October 2017. And it is estimated that the population would reach dreadly 11 billion by the year 2025. This means that more people are now being added each day than at any other time in human history.

What is population explosion?

A sudden, large increase in the size of a population is known as POPULATION EXPLOSION.

Three Main Causes of Population Explosion are listed here

CAUSES

Improvement in Public Health

Improvement in Public Health

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.

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 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

Conquest of Disease

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.
