we think to provide decreasing population all nation has implemented the birth control policy to each nation to make the possible solution of this problem(over population) to decreases them population and sterilize them included that they have only 1-2 kids per couple and make them to get reward from the government as follower the rules and regulation,,and whose person dos'nt follow do the punishment without violence their human rights,
Sterilizing people can be suicidal for the elected governments. The last time someone did that was in Peru during the 1990s. Alberto Fujimori tried to control the high birth rates of the rural population and in the end he was jailed for this.
What do you think is the best way to decrease population?
A long-term population decline is typically caused by sub-replacement fertility, coupled with a net immigration rate that fails to compensate the excess of deaths over births. A long-term decline is accompanied by population aging and creates an increase in the ratio of retirees to workers and children
