I think the Earth's supporting capacity was estimated at around 10 billion people, after that many people will lack resources needed to survive(as if it isn't bad right now at 7.4 billion). Fortunately, it's been estimated that the world population is starting to level out so we may very well never reach that carrying threshold.

I've seen estimations of carrying capacity from 10 to 30 billion. Really can change a lot depending upon life-supporting technology. I'd say it's more of a balance of good, arable farmland vs population centers since tech will still improve to support more people. Check the cool graphic out.

I've seen that before, very cool indeed! I believe Dhaka in Bangladesh is the most densely populated city in the world. I'm sure everyone could all fit in half the area of Texas, maybe a little more then half.

Have seen many estimates, with 30 billion being the highest. All of the higher estimates rely on far more equatable resource consumption and sharing. Meaning quality of life would have to take a very steep dive for many.

Yep. If everybody all of the sudden decided we're all going to move into several massive futuristic cities in the middle of the world's deserts and turn all of the remaining land into farms, I think we'd have the resources for massive amounts more people. Maybe even in the hundreds of billions with better ag tech adoption.

Whether or not we could all get along in such a situation, I don't know about the future but not right now.

I think that is a valid question but I think any discussion of this has to move to the religion thread.

On the genetic engineering part: Acceptance would depend on application, and there will always be a sliding scale.

Say there was a way to alter a single gene in a newborn reliably and without damage to the rest of the genome, would doing so be acceptable? For example, if that newborn was fully healthy except from one bad gene that causes something horrible like Huntington's diesease or cystic fybrosis? I don't see the wrong in fixing that genetic error to give someone a full chance in life instead of a certain path of mysery and early death.

The scale from fixing a clearly defective gene to improving basically healthy people slides easily though. You could consider (partially) genetic traits like intelligence, height etc als problems that need fixing. If you have one single genetic defect that causes a person to be mentally retarded or a dwarf, fixing it is easy. But are you going to 'fix' someone that would develop an iq of say 90, or a height of 5 foot?

I believe humans evolved. I think that we have reached a point where our technology and knowledge will have greater effect on our future evolution than the usual causes. if we understand it and can alter and control it, I think we should. I believe that part of being intelligent means being as adaptable as possibe. if we can better adapt ourselves, I think we should. that's not to say there are no ethical concerns

take for example GMOs. I'm not opposed to modifying food to make it better in some way, (you could argue that selective breeding over the past thousands of years of all the organisms we eat qualifies as such. virtually none of the things we grow or raise are found in nature anymore, we've changed them too much. evolution by artificial selection) but I do take offense to things like monsanto has done. things like making life patent-able. creating seeds which do not produce plantable seeds so that the farmer must come back for more instead of replanting a portion of the old. releasing roundup ready plants into the environment without testing effects. sueing farmers for intellectual property violation when wind blows pollen into another farmers field and his plants manage get fertilized by it. the plant's reproduce and their offspring are found with monsanto's copyrighted genes (despite the modification to make them sterile "life will find a way"-jurrasic park)

if you think the ethical concerns of raising someones IQ when it would otherwise just be 90 are bad just imagine if some people wanted to delibrately lower it to make people dumber. I bet such people exist

I was watching an interesting debate where Neil Degrasse Tyson talked about how we view worms in everyday life and how that would be similar to how aliens who traveled interspace would more then likely view us.

When you see a worm, you just walk by it & don't think about how it's feeling. Same for aliens. We are worms to them

take for example GMOs. I'm not opposed to modifying food to make it better in some way, (you could argue that selective breeding over the past thousands of years of all the organisms we eat qualifies as such. virtually none of the things we grow or raise are found in nature anymore, we've changed them too much. evolution by artificial selection) but I do take offense to things like monsanto has done. things like making life patent-able. creating seeds which do not produce plantable seeds so that the farmer must come back for more instead of replanting a portion of the old. releasing roundup ready plants into the environment without testing effects. sueing farmers for intellectual property violation when wind blows pollen into another farmers field and his plants manage get fertilized by it. the plant's reproduce and their offspring are found with monsanto's copyrighted genes (despite the modification to make them sterile "life will find a way"-jurrasic park)

if you think the ethical concerns of raising someones IQ when it would otherwise just be 90 are bad just imagine if some people wanted to delibrately lower it to make people dumber. I bet such people exist
Hell yeah they do. Just look at Trump. He loves them ignorant voters.

Seriously though, I could easily see some sociopathic leader engineering a low iq worker class. They'd work hard and not ask questions.

I also worry about a genetically superior over-class forming. Right now the only think separating us from them is their wealth. What happens when they've genetically modified their offspring to be superior to us in every way? Say goodbye to upwards mobility.

An even more terrifying thought is if we ever find out how to undo/stall out the process of aging. Imagine a world where despotic leaders, wealthy elites and politicians lived hundreds of years

This is a very real, scary, and likely outcome. Ironically it could also lead to the stagnation of human development.

A genetic divide, and greater separation of society between essentially the have's and the have nots, is inevitable.

I don't really want to plug politics into this thread, but this is also why an eventual global government, and universal level of care is crucial. Yes some very elite, will of course be able to do more, but if genetic healthcare and modifications are generally available to everyone, the separation to the elite will be less pronounced.

Edit: On a related note... http://www.iflscience.com/brain/new-...t-walks-again/

Heart attack, stroke, cancer. Those are currently the three biggest killers, and for all three incredible process is being made, which will again boost the population.

Of course it may be offset by the loss of antibiotics.

This is probably the only way we could ever really have some serious space colonization efforts too. As long as there's serious resource disparity and political conflict in the world, we really can't focus and unite to pull off such a massive undertaking like full scale space colonization.

Yep! Hopefully one of these days people can finally realize how we must bond together!

What if the population grew to a trillion? Would this population be to heavy for the earth to support? Would the earth fall and where?

I'm open to all the blasting that I think i'm gonna get
