Do you believe in human overpopulation?

**insert overly long winded and pompous answer here**

Overpopulation means "too many people". Any statement involving the words "too many" without any qualification, is going to be subjective. "Too many" for what? "Too many" to prevent a significant negative impact on other species? "Too many" to be sustainable living in the same way we currently do in future generations? And what do all these questions even mean? Overpopulation has as many meanings as there are people to give meaning to it, and what you think about it depends a lot on which meaning you choose.

You can think about overpopulation in different two ways. Having a lot of people is only a problem if you don't have the resources to cope with that number of people sustainably and ethically. One person can say that that a situation is an example of overpopulation, but another person can say the same situation is an example of under-resourcing and be equally accurate.

I therefore admit I am not qualified to answer this question. And I don't think anyone else is either, although I hope they try :P

Isn't that like asking if you believe the sun will shine tomorrow? "Human Overpopulation" is not an opinion or belief, it is already a fact that there is not enough food, clean water and clean air for everybody on this planet.
What's not to believe?

Haha bring up a hot topic and everyone is suddenly a scientist! Yes, I believe In it. But I have nothing smart to say.

I believe in it and I've become increasingly alarmed in my country at the birth rates. It seemed that everytime I went onto facebook someone else had babies photos up/was pregnant etc. I speak to alot of women who tell me they plan to have 3 or more children. And I can't help but be alarmed and wonder how our world's resources can cater for this influx.

The world’s human population doubled from 1 to 2 billion between 1800 and 1930, and then doubled again by 1975. At the end of 2011, it went past 7 billion. This staggering increase and the massive consumption it drives are overwhelming the planet’s finite resources such as oil, which we're running out of fast and don't have a plan.

We’ve already witnessed the devastating effects of overpopulation on biodiversity: Species abundant in North America two centuries ago — from the woodland bison of West Virginia and Arizona’s Merriam’s elk to the Rocky Mountain grasshopper and Puerto Rico’s Culebra parrot — have been wiped out by growing human numbers.

As the world’s population grows unsustainably, so do its unyielding demands for water, land, trees and fossil fuels — all of which come at a steep price for already endangered plants and animals. Most biologists agree we’re in the midst of the Earth’s sixth mass extinction event; species are disappearing about 1,000 times faster than is typical of the planet’s history. This time, though, it isn’t because of geologic or cosmic forces but unsustainable human population growth.

Today’s global human population is over 7 billion. Every day, the planet sees a net gain of roughly 250,000 people. If the pace continues, we’ll be on course to reach 8 billion by 2020 and 9 billion by 2050. I think the only solution now is to learn how to crowd surf!!

But seriously now by any ecological measure, we have exceeded our sustainable population size. Just a single human waste product — greenhouse gas — has drastically altered the chemistry of the planet’s atmosphere and oceans, causing global warming and ocean acidification.

We need to stop breeding, our selfishness to want our own children is making this world a disgusting place.

Yeah of course. This planet only has so many resources, at some point, even if everything is evenly distributed to everyone, at some point there wont be enough for everyone.

You cant seriously be asking this question. Anyone who doesn't believe in it is a moron since it exists. That is a fact. This is how it works. When we have too many of a species and too little resources between them all people start dying. You learn how this works in biology. OP you clearly never finished school or you would know this. This site is not for minors! So pick up your biology book!

that's why we need another holocaust but for everyone this time

Overpopulation doesn't just mean too many people. It also means too little resources and too much pollution for and from those people. There is plenty of space.

Asians are the majority of the world population, number in the billions and are very generously numerically represented outside of their home continent. Almost all population growth has come from the third world in the last half century. Yet we on the other side of the world, where most people can't be bothered anymore to so much as replace themselves, we worry about population growth.

Humans do great things, but they can't stop doing nasty things. Since we are on an irreversible march to our own extinction, let's do something great (to a neighboring planet, perhaps) so our species is remembered.
