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....
