To state: The current global population and the number of people are being added each day to it.

Answer to Problem 1TYC

The current global population is 7.3 billion people and 241,920 people are added every day to it.

Explanation of Solution

The global population is the number of total humans on Earth. Since the industrial revolution, infant mortality has reduced and life expectancy has lengthened. All this has caused a population explosion. Population growth is one of the major global problems.

Currently, the global human strength stands at 7.3 billion people. According to UN, global population reached 6.5 billion around 2006 and touched 7 billion in 2012. The advancing technology is to blame for this exponential rise in population.

The rate at which the global population is growing is 88million people each year. This implies that 2.8 people are added on Earth every second or approximately 241,920 people every day. At this rate the global population will sky rocket to 9.7 billion people by 2050.

Thus, control of population growth is the need of the hour.
