13. POPULATION CONTROL
There are two ways of controlling human
population
1 planned
2. catastrophic
Planned control of population:- the only
practicable method to control world population
is to reduced the birth rate. It can be achieved
by
* Education * increasing marriageable age
* family planning
14. EDUCATION
Young people of reproductive age group should
be educated about the benefits of small family.
Mass media ( radio ,television , newspaper,
magazines, poster) and educational institutions
can play an important role in this campaigning.
15. MARRIAGEABLEAGE
Present marriageable age is 18 years for female
and 21 years for males . Population experts
explain that raising marriageable from 18 to 20 or
22 would bring down the birth rate by 20-30%An
ICMR report has shown that about 49% women
in India are married before the legal age of 18
years.
16. FAMILYPLANNING
Adopting government sponsored family planning
programme since 1951, birth rate in India has
came down only slightly (from 41.7 to 28.3 per
1000 per year in about 50 years)
In 1975 , India Govt made a tentative programme
of compulsory sterilization that required one
parents to undergo sterilization after two children
. But due to public resistance , it was again
changed to voluntary approach.
