Hey i am back . I hope you all like my new content on world population .So Let's Start

From around 8000B.c to the mid 17t h century ,the plplulation growth of world greww slowlyfrom 10 million to 500 million.It was limited poplulation to sustain life on the available land.But, in 19th century, there was a industrial revolution,then there is huge agricultural productivity,due to that there was explosion in the human members of family for making their livelihood.
From one billion population people in the early 1800s,the population exanded with increasing speed, reaching7.2 billionin,2013 .More than one third of total lives in China and India. In tere is almost 1.37 billion and 1.25 billion in India. So imagine how it is difficult for these countries toearn their their livelihoop . Because working become low and poplulation grow. That's there is not job for every person in India . So we will take steps to reduce population.
There is a simple eqation that deermines
Birth rate bcome high and Death rate go low.

In the more deveoped world, population r ates are low and even more declining . Russia and Germany among otherd,will see their populations drop over the comming decades.
