PBS' Nova has produced a documentary about the impact of population trends on the planet. The supporting website provides interviews with researchers, interactive tools and trailers of the two part series.
- World population expected to reach nine billion by 2050
- 98% of growth will occur in the developing world
- Only 2.5% of Earth's water supply is fresh. U.N. reports that the scarcity of fresh water due to overuse and contamination will be the second most pressing global concern of the 21st century, after population growth.
- Human activities are releasing more carbon dioxide than the world's plants can process.
- In the next 100 years the Earth's temperature will increase 11 degrees Fahrenheit worldwide resulting in a sharp reduction of rivers and lakes, causing severe flooding in cooler regions, shifting agricultural zones and threatening hundreds of plant and animal species with extinction.
- 40% of the world's remaining forests are endangered.
- Human-induced factors are diminishing the abundance of agricultural topsoil.
- Half of the world's reefs may be gone by 2030

I never worry about overpopulation and in my opinion, not should You as according with GOD's concept of Sharing we can accommodate everyone and everything without a problem!
Ha! But there is one catch through. You must believe in GOD and also believe that He and She and everything in between will do it!
Life is precious and always welcome! -
stopnoise - no.
It is exactly that sort of blind, dogmatic attitude that contributes to the problem.
If you want to talk about "GOD," think about how badly we're screwing up his gift to us - the planet.
Overpopulation, and all the things connected to it, are obviously destroying it.
We do not have enough to "share."
We need to start strictly controlling human breeding NOW, because it affects all of us.
Think about it.
You'll most likely be singing a very different tune 50 years from now.
Also, things that are ridiculously over-abundant are NOT precious.
Disposable, in fact. -
We need to start strictly controlling human breeding NOW, because it affects all of us.
Kill yourself! -
Thanks for that incredibly intelligent and considerate answer.
I hope you didn't strain yourself.
I said control breeding, not kill people.
Though, getting rid of a whole crapton of people all at once would actually be a huge help when thinking of the Big Picture. Even if keeping civilization as we know it in tact would be no small job. -
You can believe in God, as do I, but we still have to act upon it...lol, just praying and knowing God will do it, doesn't do anyone any good. We must take action. Which posing a question...what kind of actions are we supposed to take? Birth control? With religious evangelist's who reproduce to spread their beliefs and upgrade in health care are we shooting ourselves in the foot?
-
Most certainly.
This article forgot to mention that in about 30 years the fish population will be an insultingly small fraction of what it is now due to overfishing. -
Humdrum, You lesson in life will be: Orchestra! Please, give me a tune: Tan, tan Tan taaaan,
"Sharing!"
Well, I will pray for you anyways that you will make it before the end of your physical life here on earth! It would be a shame for you to miss this graduation! -
I posted something on this topic in the thread linked above.
I am reposting it here.
I think there is another side to this concept of overpopulation that perhaps all of you have not considered.
Back after the second world war, when all the "enlisted" men came back to their homes and farms, the world was scarcely 2 Billion at that point; what with the loss of literally millions of people during that war. At that time more that half of those 2 Billion were literally starving and there were food shortages in many parts of the world and yet the United States government instituted laws created that literally paid farmers not to produce food. America had plenty to eat, but why would our own government pay farmers to not produce food when half the world was starving?
It is simple really, it was because of fears of overpopulation.
People have been talking about overpopulation since before the turn of the 19th & 20th centuries. World leaders (aka the money elite and future WTO) held conferences and had statisticians prepare data to project the population of the world would be by the year 2000. Estimates ranged anywhere from 5 to 8 Billion people and economists studied what the impact of that would be. Predictions were dire and economic collapse was seen as an inevitability if the world was allowed to reach such proportions.
Many policies were established and disseminated to governments everywhere through think tanks and universities. People were gradually being prepared for radical moves on dealing with overpopulation. Birth control was floated as a possible remedy to promote to the masses, but this strategy was met with fierce opposition from Religious organizations. So more subtle population control methods were brainstormed and established.
War is always one of the ways to keep people dying. Starvation of course will always be the leader because of the policy to pay farmers not to farm only megagricorporations have taken over the food supply to 90% of the population.
None of this makes any sense unless you were trying to keep the population down.
Then comes AIDS conveniently enough that guarantees to wipe out at least 1/10th of the world's population every year in an ongoing basis. What a great disease to accomplish goals that led some countries to institute policies of genocide; lest we never forget the Holocaust or the atrocities committed by the Japanese against the Koreans and the Chinese.
It's just my opinion but population control seems to be a slippery slope. -
I'm adopting. I think it's an option everyone should seriously consider.
Why bring another kid into this world, when there already are a lot of children, suffering and underliving? -
It is a little chocking to see people that do not really believe in GOD talking about humans like they are horses or chickens and we can just do this and that and kill this and control that. Hugh! I guess I just have a better respect for humans and life than this way of thinking.
When you are talking about life on this simplistic and horrific terms you degraded it to the level of an object. In addition to that I find it quite paradoxical how people conspire to prevent or destroy other people lives. Nevertheless they never think for a moment that to them were given by the SPIRIT of GOD the opportunity to be here.
Yes! here is the solution! Everyone that thinks we have too much people on Earth and that we should eliminate or prevent some one from being born, please, start by giving us your own example, Just Kill yourself then! If you kill yourself there will be one less individual on earth and all our problems of over population maybe could be resolved by you guys!
Now, show me that you are brave and you are going to help us to control overpopulation by doing what you preach?
People, Government and Societies have always tried to control Life, but Life somehow and miraculously always find its way through. Praise GOD! -
LOL looks like earth is turning into mars.
-
So, to summarize: we're fucked.

jade, great thinking. I feel the same way. Stopnoise, it is great if you'd like to believe that. However, it is very irrational and scientifically untrue to think that humans are much different from other animals. It's sequences of amino acids in our genetic code that exists in every single one of our cells that allowed humans to grow brains and become conscious of our surroundings.
Then again, I'm not going to go on a rant or tirade to try to sway anyone's opintion because that is futile. I respect your opinion, unscientifically sound as it may be, but please realize that there are millions of people in this world who are trying to change it for the better, and who are utilizing the resources we have at our fingertips to make do with the limited resources our planet must learn to share between a growing number of people.
As for the overpopulation issue, adopting is a great way to fight this overpopulation issue we are facing. -
Urkovs, I had no idea you had such lack of consideration for humans to the point of comparing it to animals. I think some call this type of thinking "The Myopia of the Brain."
You know the say:
"If you cannot show respect for your own self, how are you going to learn how to respect others."
With your philosophy and thinking, you are hypothetically taking the whole Scientific Community Voice's and suggesting to be; (irrational and untrue); to respect human life and to recognize that we are not equal or less than the animals.
Like I said before, I do have the solution for your Overpopulation Issue!
Everyone that thinks we have too much people on Earth and that we should eliminate or prevent some one from being born, please, start by giving us your own example, Just Kill yourself!
Just think about how simple this is and how it makes a lots of sense. If you kill yourself there will be; (one less individual on earth); and all our problems of over population maybe could be resolved by you guys!
Oh my GOD, he, he, he, LOL!
I think I can bring this dialog to the Comedy Club down the Street and make some money with it.

why kind of person preaches about GOD then tells you to commit suicide.
You're no better off then them.
holier then thou?
i don't think pushing your beliefs onto other people makes you any closer to your god.
if god is all loving then i guess humans are equal to animals? and yea, we would share this planet with everything other living thing here... down to each blade of grass...-

For awhile I have been thinking I must adopt instead of giving birth to my own child, for the sake of our planet. Plus I'm not too sure if I truly want to bring a child into this world, with how grim our future is looking. But then my intense maternal instinct cries out and I get an overwhelming sensation that this will mean I'll never know what it's like to give birth or what it would be like to raise my own child, a little boy or a little girl who's a lot like me. . .
It makes me so sad that we as humans can't figure out how to stop all of this madness! It makes me angry that the people at the top, with all the money, the ones who are controlling and destroying our planet, are OBVIOUSLY thinking about themselves, and the NOW, and not the FUTURE!! If they did care about their own children, grand-children, or great grand-children, they wouldn't treat the earth as they do! Stop sucking the earth's blood dry, aka OIL, stop deforistization, stop vacuuming out every bit of fish in the sea, stop it all!
Over population is a huge crisis! At this point, I don't know if there is any turning back. 100,000 killed in Burma because of a cyclone? Dead bloated animals floating next to dead humans, God rest their souls. Our world is so f*cked up! I was always an optimist, but everyday I get more and more realistic and become incredibly pessimistic...-

That's funny because I didn't think that Malthusians still existed. Before we run our mouths lets pick up a book.
How long will we choose to be ignorant? Malthus was wrong in 1800 and you are wrong today. As the population increases so to will innovation, as the developing world becomes industrialized its birthrates will level off. Just look at every industrial country. People have more children when they are poor, this is a fact.
As a student of economics the irrationality of peoples beliefs and actions startle me.
Do we choose to forget the past so we have something to talk about or are we all just incompetent? -
I think I'll move to Mars!

The uberlords would love for us to think that we are the problem here. Too many people. If we made less weapons and grew more food, if we wasted less energy on things not really of importance, if we used proper energy sources and did not allow corporate pollution...we could support a whole lot more people on the planet.
It is not how many people, but how we are living and how we are disregarding the natural laws on the planet. -
Don't be neither surprised nor alarmed: Just commit yourself to something environmentaly friendly !
1.000.000.000 all the way up to 1810, then 9.000.000.000 by 2050.
What else are we going to accomplish within these 250 years?
Depends on me, depends on you!
We are looking for a partner for an interesting agro-forestry project! Any one with more than thoughtful words out there? Visit: therightchoice.tv and welcome to, more food, more energy, more pure air!

I too believed this nonsense until I heard about the Replacement Birth Rate.
If you look it up at the United Nations site you will find that most countries now have a lower birth rate than the replacement rate of 2.1.
Now, for some years, in Europe, those countries have been begging their people to have children. As the population ages, with better health care and a lower birth rate, some nations begin to have severe problems. As people retire, who will do the work?
And of course, the current infatuation with Abortion doesn't help the matter much at all.-

Humdrum,
Then I sincerely suggest that you never have children.
Sounds like more profound wisdom from the "me" generation.
What's next? Dispose of everyone over 30?-

Urkovs,
Another voice from the tribe of the great unwashed that don't believe in God?:)
Hmmmm..maybe if you did you would have a much different viewpoint?
That's ok, you can believe anything you want but kindly don't impose your standard of humaness on the rest of us ok?
Other animals, including whales and dolphins did not crawl up on land and stay. They did not walk and did not learn to use tools and did not learn languages like humans did.
They did not decide to build houses and cities and did not discover electricity or how to build cars.
They did not decide that they needed to go faster and figured out how to fly through the air or into space above.
Now, how are we exactly the same as these other animals?
I beg to differ with you.-

BIRTH CAP! BIRTH CAP! BIRTH CAP!

I've known for a good long while now that, if I ever have any kids, they'll be adopted.
I don't claim to hold any profound wisdom; I have my supposedly informed opinion on the matter, just as you have yours.
Though that's very true about more developed nations having lower birth rates, there are far too many "underdeveloped" / developing nations, complete with massive populations, to just write off, in my opinion.
My Christian grandparents actually feel the same way about overpopulation, as do their friends; I'd consider them wise well before I'd consider myself wise, much less some stranger on the internet, no offense.
Also, thanks for not telling me to off myself, as one "Christian" just did. That's just missing the point entirely. -
As far as I'm concerned, the Malthusian principle is only truly showing up now. Innovation has brought us this far, but as far as our food supply is concerned, you'd better tighten your belt because our industrial model of agriculture that currently feeds us is on the brink of collapse.
Nature operates on a cyclical base, and we all have been taught time is linear. Here's where we get the rude awakening, because if we don't think about it and limit ourselves and treat our planet with care, she'll just run of of resources that are available to us, we'll die of war and disease and starvation, and either a few of us will be left and start over or another species will take over.
And limiting ourselves is the only way to decrease population because Humdrum is right, there are too many "underdeveloped" nations trying to live the American lifestyle, which is completely unsustainable.
We're about to run out of oil, our soils are degraded and salinated and eroding away, and we're spewing that carbon out like its no big thing. War and disease are good population checks, but if we were smart about it and used that intelligence that seems to "separate" us from the animals (I personally think they're smarter than we are, look at the mess we've made for ourselves), then we would rethink our current notion of progress. Anyone catch Vanguard last night? City on Steriods? Yeah. -
This is why adoption is critical. Especially as educated people we owe it to the world to take a hard and honest look at these facts - go beyond acknowledging their existance. Is it a hard decision regardless to give up the idea of 'producing' a child versus being content adopting?>

Wow! So we can adopt, kill one another, wait for deseases to ravage us, assume someone else like the government is working in clandestine ways to control the population or assume God will step in! Looks like we're in good shape and can just keep on popping out children here there and every where ad nauseum because, Gee! we're not animals after all. We're God's chosen, or is that only the Jews that are the chosen few, or only the Islams, or Mormons, or - well - God will figure it out won't s/he?
On the other hand, there are so many good oportunities to influence the future of life (all of it) besides the goodness of adopting those already here on this planet. All one needs to do is pick a topic (overpopulation, fresh water shortages, food shortages, resistance to wars, restoration of vegetation, purification of commons, reduction of energy usage, etc, etc, etc) and dedicate themselves to doing something about it. That way those that are adopted have a life worth living.-

stopnoise ... sorry, even with all the intelligent comments in between i am amazed that someone who may claim spirituality would say something like this. incredible. this is why we see those who follow religion adamently and adhere to outdated birth control practices have 19 children and i, who would love to have just one, feel guilty about not taking steps towards negative population growth (the only way to save the planet at this point it seems...)

notonourwatch - I concur! We must respect our unique human qualities by using them for the better.
In the recent (and historical) aftermath of natural disasters, disease, and the numerous human conflicts, it becomes apparent that we are not in control. We must remain humble in the presense of Earth, Mother Nature, God, or whatever you believe. We've gone too far and the earth is letting us know. In the back and forth future of humanity we must try to find a balance in life.

HollybyGolly - I agree with you. I believe we can still save our planet, but we have to start working together instead of slinging insults and hate at each other.
People have said they can't see bringing a child into a 'messed up world like this' for hundreds, if not thousands of years. That one child may save the planet. Stranger things have happened.
