A sudden increase in the size of the population is known as population explosion. The world population had reached from 2 million in 1900 to about 6 million in 2000. Such population explosion can be because of many reasons such as:
Decline in death rate
Decline in maternal mortality rate
Decline in infant mortality rate
More individuals with reproductive age
Increased rate of immigration
Increase in life expectancy.
Methods for controlling Population Explosion:-
1)The most common method to control population explosion is encourage small families about different control measures such as contraceptives.
2)Periodic abstinence is the natural measure for control. In this mode, the couple avoid coitus from day 10 to 17 of the menstrual cycle. These are the days when ovulation is expected. This period is known as fertile period as the chances of mating between the egg and the sperm is maximum at this time.
3)Withdrawal or coitus interruptus is another method for control where male partner draws his external genitalia or penis just before ejaculation. This is done to avoid insemination.
4)Lactational amenorrhea is absence of menstruation during lactation just after parturition. The chances of conception are minimum during lactation. But this method is effective for about only 6 months after parturition.
