Increase the availability of Birth Control, potentially make it free. Educate young people to prevent unwanted births. In extreme cases introduce sterilisation. Introdce one child policies such as china's.
Usually countries just try to do it by educating their people. There is a movement called Zero Population Growth which encourages people not to have too many children.
The Chinese Government, of course, famously passed a law allowing only one child, and families are fined if they have a second child. The concerns with overpopulation is that there are getting to be too many people for each of us to get enough resources to live our lives free of hunger and disease. To have the energy to manufacture goods and keep warm. To have places to live, water to drink, social amenities like schools and hospitals. To many of us for all our waste to be treated.
The answer to overpopulation is to maintain the number of people to the point that there is enough of a population to create the social and lifestyle conditions we want, but not so many that the resources cannot meet their needs
That gets us to the biggest problem with finding or enacting a solution:
Overpopulation is a problem usually expressed as there being too many of "them". "We" are okay.
As a consequence all of the answers to overpopulation are met with the same responses as the proposals for control of global warming:
* There is no problem. * Why should "we" put ourselves out when "they" are just going to eat up any improvement we make. * We're okay, let "them" solve their own problems. * We will eventually solve the problem without population control by developing new technical answers * It's too big to tackle.
Observations of nature suggest that the problem of overpopulation will eventually sort itself out. When any population gets too big it suffers from a massive die off due to disease or social stress. In the case of human beings we could add war to the list. This could get messy as these solutions will impact everybody, not just "them". Also there is a tendency for natural or uncontrolled solutions to over-correct the problem. Instead of our present several billion folks we could end up with a few hundred thousand -- enough to breed and continue the species, but not enough to continue the civilization or the technology.
So what can we do? As individuals, very little. As individual countries, not much more. As a majority of the human race maybe.
We'd have to agree to:
* Work together for a solution. * Share what we have until we get to the solution. * Abide by the solution after it is available.
The"solution" is the hard part. Writers of Science Fiction have come up with many, but none seem overly pleasant. Controlling birth by universal birth control, licensing or social pressure is often mentioned. Reducing medical care for the infirm is a potential solution that flies in the face of humanitarians. Some writers even suggest making life or death lottery choices a routine even.
With a male birth control pill (that is swallowed or injected). If men had a birth control pill, most male would probably use it. Of course, no birth control pill protects against sexually transmitted diseases, however, if there were a male birth control pill (and an Israeli doctor claims to have invented one), the population would probably gradually go down in most countries that practice birth control.
You cannot.
People are people not experimental animals. If people want to overpopulate and kill off the human race there is nothing short of a world total Dictatorship that will prevent it.
War and disease always worked effectively in the past.
If "you" is the government, the most frequently used methods are either simply by Propaganda, or subsidizing.
Propaganda is commercials really. Want fewer children? Show pics of happy couples only raising one child. Want more children? show pics of big, happy families.
Subsidizing can be by giving a tax cut to bigger families, or stating a law about more maternity leave etc.
kkill everyone
education
no
Yes
birth control .and have the contraceptive to control the over populated country
Because it cant control its population
bomes or a gunfight
It's necessary because know the population will help know how many schools, wells, and other public places the country will need
