Question

What was the world population in 1800 as is given in chapter 'The Ailing
Planet' ?
(A) One billion
(B) Two billion
(C) Four billion
(D) Three billion​

Answer 1

The population was one billion.

• According to the author, it took more than a million years for humanity to hit the billionth individual. About the year 1800, this happened.

• However, by the twenty-first century, the world's population had risen to an estimated 5.7 billion people.

• Every four days, one million people are added to the world's population. More children do not imply more hands to work, but rather more people who are unemployed.
