[b][size=4]Earth population 'exceeds limits'[/size][/b]

[img]http://geology.com/articles/what-is-earth-science/earth-science.jpg[/img]

There are already too many people living on Planet Earth, according to one of most influential science advisors in the US government. Nina Fedoroff told the BBC One Planet programme that humans had exceeded the Earth's "limits of sustainability".


- Current world population - 6.8+bn
- Net growth per day - 218,030+
- Forecast made for 2040 - 9+bn
[size=1][url="http://news.bbc.co.uk/1/hi/sci/tech/7974995.stm"]Source[/url][/size]

Earth population 1980 - 4,453,831,714+
Earth population by 2020 - 7,584,821,144+
Earth population by 2050 - 9,346,399,468+
[size=1][url="http://www.infoplease.com/ipa/A0762181.html"]Source[/url][/size]

With the price tag of "standard of living" going up and up each year, with more people going below the poverty line, less jobs becoming available with more people claiming benefits, when it too much, enough?

What's the answer? Cut down on the love making, or is it time to move onto the Space race of liveable space stations/another planet (Mars)?

It was already too much many decades ago. The earth under normal natural conditions has a maximum capacity for about 1 billion people, yet we keep stressing the planet even further to suit our needs. At some point, something's going to give. Food supplies are already short in many parts of the world and current energy resources are getting thinner (not saying that if everyone starts investing in alternative energies that nothing more can be gained). That space race isn't going to happen in the next 50 years (Mars) and we won't be able to colonize other planets in time before we suffocate.
At some point it will either be voluntary sterilisation or some form of war that will sterilise/erradicate a big chunk of humanity for the planet's resources, there's no doubt about that. Humanity has become a plague that feeds of the planet like a parasite.

Can you provide a source for that? Because I disagree, and my evidence is the fact that we are 6 billion+ people and there is still more space.

As for the comment on food supplies, the fact is that we have enough food to feed everyone in the world right now. It doesn't happen because we don't distribute it correctly, leaving some people with nothing and leaving others with so much that they end up wasting what they have.

yeah just wait for the day when we have a "third sex"... aka you where fixed at birth... you are still a male or female, just never will reproduce... done just to reduce the population randomly

and most places there are a shortage of food its because of the location they are at... like in parts of africa where its hard to support large crops of food and has to be brought in from other locations

It's a quote by many biologists and it's been quoted by Sir David Attenborough on many occasions in his documentaries. The keywords are "natural conditions", because what we are all living under and reshaping the earth to suit our needs are unnatural conditions.

I find it hilarious people worry about this problem. Trust me, if there's too many of us, the Earth will take care of that all by itself.

A better question is how many people can the Earth comfortably support, which, since we haven't stopped reproducing, is apparently more than how many we have right now. That's an issue humans can self regulate.

I'd also like to point out that along with these "fewer jobs, more poverty" claims comes advances in medical care and technology unheard of 50 years ago. If resources are really the issue, we could give a lot of it up, fewer people could work at manufacturing jobs, and we could drop the life expectancy some.

Really, so some how figured out that there are to many people and think the growth should stop? There have been people over the last 400 to 500 years claiming there were to many people in the world, whats any different now?

Sorry, but the science doesn't add up, there is more then enough resources and capacity to handle. The majority of the world is open and un-used. The resource constrains are man-made. The majority of the scientist making these claims alarmist who make these forecast that never come true or that are never held to account for.

As countries develop, the population growth will eventually stabilize and possibly reverse. Statistics have already shown that while we are living much much longer, we are also choosing to have kids later in life on average. Can't find any scholarly sources that are free to the internet. Really wish the sources that you have access to through college libraries were open to the public.

there's a fantastic TED Talk (13 mins) in which the speaker shows how religion affects birth rates around the world. The point to take away from it (towards the end) is that religion doesnt affect birth rate, women are having fewer and fewer children, and the global population will level out at 10bil.

There are two different things here (physical vs resources) - the Earth physically can easily sustain 10+ billion people. The whatif on xkcd said you can cram all the people in Earth in the state of Rhode Island. Resources wise, we should be able to sustain more people, but we may have to change habits for that.

I say we find something useful to do with all that space in Russia :p

Although seriously, I think at some point in the future to remain sustainable, we're going to have to probably start heading down a very GM centric route in regards to animal & plant production.

I don't see how the above is any different than the last 8000 years hell the last 50-70 gave us the green revolution

Overpopulation is a myth. Every person on Earth could fit into the land area of Texas and have a comfortable living area to themselves. Yes, some places on Earth are crowded and some places simply can't be populated, but there is a lottttt of room that can be used. The US alone probably has the capacity for billions of people. Granted it would involve cutting down a lot of trees, but it's possible.

It's more about having the resources to comfortably sustain ourselves and being able to continually replenish our resources, rather than how much space we have. Hence why the issue is more considered as sustainability rather than overcrowding.

I think there is plenty of space like some of you mentioned, but we have to learn to take care of our resources and environment and then we will be fine. If we do not then we will start to perish due to lack of food, water, energy we use to do the work, disease, pollution, etc.

youre right about a "very GM centric route" but there are a LOT of GM crops already. even animals are mass produced. kinda sickening to think about, but necessary, unfortunately.

again, the issue isnt about the land mass necessary to sustain the population - there's plenty of that. it's all about the resources.

If you were present with the ancestors of the crops before humans started medaling with them you would think you were on Pandora

This GM has already happened, Its been happening for thousands of years.

You say everyone can fit in Texas , what about farmland?

The UK is a giant farm if you look from the sky yet we need to import food.

That's because all that farm land is used for corn to make ****ing fuel and corn syrup.

There are ample resources, though they are finite and non-replenish-able. Contrary to popular belief, we can end world hunger. As for sustainability, the answer lies in how much better off one wants to be than the next guy.Overpopulation is only a challenge for someone who wants the cake and eat it too.

And how does she know that exactly? No one has surveyed the earth's resources to determine what it can sustain. Furthermore, we have a situation where a large amount of the population is starving and without access to clean water, shelter, or basic medication, yet there are others who waste (the west) vast amounts of food, energy, and water. As well as hoarding wealth and resources that could be shared throughout the world and give everyone a good standard of living. The John Travolta's of this world, with their private planes and runways, and gigantic mansions make me sick. All the while people are dying because of simple preventable illnesses and malnutrition.

Yes there are too many people on this planet - hoarding resources that belong to all humans. Additionally, it has been shown countless times that educated humans have smaller numbers of children. So you see, if we all had equal access to the same resources and education, then the population would regulate itself.

Once again, it's not about space, it's about resources. It's funny that only a few of you seem to get that. Sure we could cram more and more into a tiny space and let the rest of the Earth be farmland, but the Earth does have its limits.
Unless humanity starts changing the way it consumes energy and other resources there will be a huge problem in the next 100 years.
Oil and food will be short and those will be sold at premium prices that most will not be able to afford.
We need different energy and food sources. And yes, even those genetically manipulated crops are showing signs of failure as many that were engineered to be resistant to certain bugs are already showing weak points and those bugs are the ones becoming resistant to those crops and eat/attack them once again.
And those that think we will level out...I think we wont, the number will rise exponentially untill some form of disaster happens or we limit population ourselves through diverse means.
Advances in medicine are one of those things that is changing the natural order of things. The survival of the fittest rule of evolution no longer applies because of it in this day and age (and this is coming from an MD).
I'm not saying what I'm doing as an MD is bad (I love helping people) but we are the ones that have changed the human population drastically from what it was 100 years ago and many people that would have died of natural causes, simply haven't and have been given a chance to procreate and increase our numbers.
If that immoratlity gene becomes reality and its use becomes widespread and we still procreate the way we do know, then the sh*t will really hit the fan, so to speak.

The earth has apparently been feeding life for millions/billions of years, I highly doubt much is going to change in another 100
