POPULATION EXPLOSION

Population explosion is not only a problem in India, but all over the world.The population of India was around 361 million during the census of 1951. It reached over 1.34 billion now.India, is the second most populous country in the world, while China is on the top.With the population growth rate at 1.2%, India is predicted to have more than 1.53 billion people by the end of 2030.

WHAT IS POPULATION EXPLOTION

Population Explosion refers the sudden and rapid rise in the size of population. A drastic growth in population beyond normal limits is called population explosion. It is more prominent in under-developed and developing countries.


CAUSES OF POPULATION EXPLOTIONPOPULATION EXPLOSION

1. Accelerating birthrate: • Due to lack of awareness about the positive impact of

using birth control method , there has been a steady growth in birth rate.

2. Decrease in infant mortality rate:• Improvement science and technology and wide usage

of drugs has reduced the infant mortality rate.

3. Increase in life expectancy:• Due to improved living conditions, better hygiene and

sanitation habits, better nutrition, health education etc. the average life expectancy of human population has improved significantly.

4. Increased immigration:• It happens when a large number arrive at an already

populated place with intention to reside permanently.

EFFECTS OF POPULATION EXPLOTION


1. Over population:

It is a condition where

population surges to a

level that the earth cannot

accommodate comfortably and poses a threat to the

environment.

2.Unemployment:In developing countries like India with a backward economy and little scope for fruitful employment millions of people find no work to do.

3. IlliteracyPopulation explosion is the key reason for illiteracy in India. Because of illitteracy people are not caring the environment

4.Poor health:When there is high population growth people do not get adequate food and nutrition. Then they may suffer from poor health.

HOW POPULATION EXPLOTION EFFECT THE ENVIRONMENT

More population means more mouths to eat food which requires more agricultural production. More cultivable land has been made available by clearing forests and by reclaiming wet lands and ponds. Advanced agriculture requires utilization of more water, more fertilizers and more pesticides. And it demands more space to construct houses and availability of more consumer goods. It also requires more means of transport, more consumption of fossil fuels, and more pollution of land, air and water thus growth of population leads to pollution of land, water and air

EFFECTS OF POPULATION EXPLOSION ON ENVIRONMENT


EFFECTS OF POPULATION EXPLOTION ON ENVIRONMENT

As the population grows, more And more forests are cleared.

The two most common reasons for deforestations are to make houses for increased number of people to

live in, and to use wood as a fuel in the industries. As a result the trees

that help us in reducing the air pollution through the process

of photosynthesis are not able to

do so any more.
