Three ways of curbing the exponentially growing population of Asia are:
1) Development: Why the enormous population and the increasing rate of it is the biggest challenge faced by the developing nations of Africa and Asia while the same is a little or no threat in countries like America, Europe or Japan. Lack of Development implies high poverty, high illiteracy, high discrimination, lack of awareness, lack of medical facilities and thus in turn increased population growth.
2) Easy and cheap availability of contraceptives: Ensuring that people have easy and cheap access to contraception tools will help avoiding cases of unwanted pregnancies and births. Every state owned hospital should be made to provide cheaply efficient birth control medicines or surgeries since poor people have neither the means not awareness to use contraception. Use of contraceptives must be advertised and promoted along with ensuring cheap and ready access to these. Contraceptives do not only prove to be an important population control measure but also prevents spreading of sexually transmitted diseases like AIDS thus ensuring small healthy families.
3) Education: Education forms the backbone of an individual and economy. Education, especially women education, can work wonders in controlling population. An educated man and woman can readily understand the benefits of a small family. Without sufficient education most measures like awareness campaigns and women empowerment will prove to be insufficient and pointless.
