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.

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.

every country imports food, heck the USA imports food, and most of the midwest is farm land

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

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.


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.

Earth population 'exceeds limits'

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".


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.

The earth under normal natural conditions has a maximum capacity for about 1 billion people


Funny, I don't see people tripping up all over each other with over 6x more than your number there

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

Not in these numbers with such a huge amount of biomass it has. That has never been the case.

People mass combined vs Earth mass is absolutely no comparison, the Earth is not just its surface, there are miles deep of resources, nothing is going to happen in 1000 years let alone 100

If you truly believe that and think we get our food from miles deep, then wow. Good luck!

Food doesn't grow underground... at least not a whole lot of it does. Most requires sun light and air. Can't farm miles deep in the ground very well. We can only use so much of the resources before we are screwed. Not sure if you are trolling, as I know you should be able to understand such a simple concept....
