what are the causes of overpopulation?

Lack of birth control planning in most poor countries.

Populations grow explosively when the birth and immigration rates are high and the death and emigration rates are low. Less developed countries have high birth rates either because standards for family size haven't changed or because some religious wackjob won't let them use effective birth control. And the countries have low death rates due to improved sanitation and healthcare. Hence, explosive population growth results.

What is fair about someone coming in and changing my standard of living because they want more.\n\nOne way or another it will be resolved here. We will either become an exceeding poor nation with few resources to help the overpopulation. Or others will have to survive in the own country  and people here can survive the best they know how.\nLife goes on either way.

I've also heard of studies similar to those you're referring to; I agree 100% w/ you that high population density is a pretty feasible reason for homosexuality and violence, these may well be nature's "control mechanisms" for avoiding LOCAL overpopulation. As far as the whole world being overpopulated, I don't agree w/ you.... food production nowadays, for example, could feed more than 100% of the world's population adequately if equally spread among all human beings; furthermore, global birth rates are rapidly declining, which could actually lead to global UNDERpopulation just a few centuries from now.

The government is unfortunately less inclined towards preventing problems, such as overpopulation, and more inclined towards fixing current ones, such as providing food for the ten children in a family.  I definitely hear what you're saying though, and I think a tax benefit should be given as incentive for not having children.  Talk to your congressman.  Unfortunately, though, I doubt you'll make any progress on this problem under the current administration.

The population tends to increase faster than the food supply.\n\nIn general, at least with humans, the population increases exponentially while the food supply increases linearly leading to shortage/hunger.

I dont think it has anything to do with population.  I think it has to do more with the fact that there are a lot more things to do than ever.  People work more that one job, kids are into lots of sports, going to the malls, etc.  This happens in large and small towns.  I lived in a small towm most of my life and now that I am in a larger city, I interact with people a lot more.

It is a symptom of a much bigger problem, namely overpopulation. This world is finite and if humans don't find a way to thin the herd mother nature will.

High birth rates are a global problem.  It would be better if everyone limited themselves to one or two children.  That kind of global thinking won't happen, though, until education is valued by governments and all people are made aware of the world overpopulation crisis.

pro choice.\n\nwith 6.2 Billion people on the planet, don't you think it's about time we start thinking about population control?\n\nNow if only the rest of the planet would start thinking this way

Japan´s population has very low population growth, and has been going on for 20-25 years. \n\nChina is not overcrowded. Have you seen the amount of land they have? But yes, population grew at very high rates, so since the 1970, goverment has been teaching about birth control and forcing just 1 child per family.

I agree with the ruling but could never do it myself. Lets face it overpopulation is the root of all our problems. pollution, hunger, disease, war. So it is a necessary evil. Unwanted babies very sad.

If it's 1 child, it's because there are 2 many people and too little money and food resources to feed so many. With no population control policies the government would have a disaster to manage
