Reasons Of Population Explotion

Now since we know what is population explotion , its aftermath as well as some of its reasons so lets move on further with our knowledge.

The world population has not been stable. Like for example in 1820, the world's population had reached 1 billion. A hundred and fifty years later, in the early 1970's the world's population had reached 3 billion. In 1999 , the population doubled to 6 billion. And now we can do the math that in 2050 the population would increase to 7.5 - 10.5 billion. If it goes on like this then in no time the world is going to shrink and human's would overwhelm from it.

Why is it so that the population is increasing????

The main reason for this is that with better food supplies and medicines, deaths are reducing, while the number of births still remains fairly high.

increase in birth rates due to medical improvement, decrease in death rates due to better medical facilities and improvement in the field of medicines, availability of health facilities,

Besides these . Migration is another reason which determines the size of the population in a place.

Therefore population can be stable if it is balanced....

THE KNOCKING EFFECTS.

Hey, do you know that the effects on our Earth and its natural resources due to the increase in our population is not simple at all. I have found some of the effects.The effects are very dangerous. The knocking effects are-

1. People are cutting forest trees and using that land to build houses, industries.
Land is becoming scarce.

2. Since people are using forest land. Therefore, it is effecting the animals, birds and other organisms of that nearby areas. Sometimes some animals like elephants enter into the towns in search of food. Birds also come to the cities in search of food.

3. More people means more need for natural resources like water, minerals and more agriculture to feed the population.

4. The population of people are increasing and the wastes produced from the houses are also incerasing. These wastes are pollluting the EARTH. These wastes also seems to be very dangerous for the animals and the ecosystem.

5.People are now fighting for water availability, for land and what not. Everybody wants to get more but the availability of resources to feed the people is less.

These are some of the knocking effects. I do hope that we will, and can reduce these effects and save ourselves as well as the nature.

POPULATION boom!!!!

Population a boon or a curse!!!

How can population be a curse to us? Many of us might think that. Well for some of us, increase in population can be a boon like Sudan, a country located in the African continent, has experienced a loss in population numbers due to emigration. But in countries like India population has increased to such an extent that it has led to population explosion thus exploding like a bomb kaboom!!! this has caused problems like less of adequate resources for each individual, malnutrition,poverty, unemployment etc. So,it is an intense problem and must be dealt wisely.

DECREASING SPACE.

Hey freinds, before saying something, let me ask you all one question. Have you ever realised admist a traffic jam or in a crowded bus that why there is so much vehicles, people, noises all around. Of course, you think how to get rid of these disturbances first.
All of us have realised that the world has changed a lot. The green fields, trees laden with fruits and flowers, clean rivers are all disappearing slowly.The spaces are filled up with houses, buildings and industries. And the population of human beings are increasing which is effecting our natural resources to a great extent. Because of our growing rate, all these weird things are happening on the Earth. Its a high time now to do something. So, we have to join hands and put our efforts together to reduce the human population as well as save our MOTHER EARTH.

Overpopulation

Population increase is a major problem now-a-days.It's leading to overpopulation.

Overpopulation is a condition where an organism's numbers exceed the carrying capacity of its habitat. The term often refers to the relationship between the human population and its environment, the Earth.Steve Jones, head of the biology department at University College London, has said, "Humans are 10,000 times more common than we should be, according to the rules of the animal kingdom, and we have agriculture to thank for that. Without farming, the world population would probably have reached half a million by now." The world’s population has significantly increased in the last 50 years, mainly due to medical advancements and substantial increases in agricultural productivity.

The overpopulation is causing a lot of problems,such as:

* Rising global temperature.
* Shrinking amount of cropland per person.
* Decline in amount of wheat and rice grown per person.
* Shrinking area of tropical moist forests.
* Decreasing oceanic fish harvest per person.
* Increasing number of people dying of AIDS.
* Declining human sperm count.
* Growing gap between rich and poor.

I want to show how population is increasing through this maps:
