RE: Doomsday prediction or uncomfortable fact
Much of the soils used for agriculture have already been depleted of nutrients and you can't grow much without artificial fertilizers. However there is still a chance for fixing that for now. Out of the 6 plant macro nutrients, the only one which is not abundant in seawater or air is phosphorus. The current reserves will last somewhere around a century and if we switch towards sustainable agriculture in the following years, instead of continuing to waste phosphorus, we might be able to enrich the soil back to the necessary P levels that allows agriculture to sustain itself indefinitely.

According to the U.N. Population Database, the world's population in 2010 will be 6,908,688,000. The landmass of Texas is 268,820 sq mi (7,494,271,488,000 sq ft). So, divide 7,494,271,488,000 sq ft by 6,908,688,000 people, and you get 1084.76 sq ft/person. That's approximately a 33' x 33' plot of land for every person on the planet, enough space for a town house.

Given an average four person family, every family would have a 66' x 66' plot of land, which would comfortably provide a single family home and yard -- and all of them fit on a landmass the size of Texas. Admittedly, it'd basically be one massive subdivision, but Texas is a tiny portion of the inhabitable Earth. Such an arrangement would leave the entire rest of the world vacant. There's plenty of space for humanity.

Population growth is slowing globally, and in certain countries birthrates are below replacement level and have been for some time now. If we want to keep the current trends as they are, or accelerate them in a more benign direction, we are going to have to spend money to save money, in other words there needs to be a global effort to raise living standards and improve education, especially for women, since those are correlated with low birthrates. We have more people and livestock producing more sewage, and this is a resource that is currently scandalously under-utilized. The stuff that we and our animals shit out is either expensively treated for the benefit of a well-off minority or is simply pumped into the nearest handy body of water. All that nitrogen and phosphorous that humans and animals take in with their food has come out the other end sometime - why not take advantage of that fact? we're more clever and imaginative than that, and in terms of raw resources most of the ones that aren't effectively limitless can be recycled indefinitely.

RE: Doomsday prediction or uncomfortable fact
It isn't how much space you need to live on that is important, it is how much space it takes to support you, which includes housing, feeding, filtering waste products, schooling, entertainment and the eco-systems that replace the carbon dioxide that we breath with oxygen. Using human waste as fertilizer has the problem of passing diseases around.

I personally believe that the human population is too large in some areas of the world already. I would hate to live in a city like New York or Tokyo. I would feel like a sardine in a can.

When I find myself in times of trouble, Richard Dawkins comes to me, speaking words of reason, now I see, now I see.

That's really a non-issue.

I've lived in New York and it isn't bad at all. I love big cities and miss living in one.

RE: Doomsday prediction or uncomfortable fact
Yeah, I guess your right. I grew up in a town of about 10,000 people and I could get out of town on my bicycle in less than five minutes. I love open spaces.

If the data that you present is accurate, that is good news, I am just not convinced that it is all the data. I also suspect that some of the missing data may not be as rosy.

RE: Doomsday prediction or uncomfortable fact
Still I see no one addressing the effects overpopulation has on the environment.
Global warming and pollution are starting to affect our ecosystem even as we speak.

I have heard success stories ; just recently I heard the history of a japanese industrial center that went from high pollution rates and brown skies/seas to a clean metropolis.I think the story is referring to Akita.

In short what are your thoughts on environmental degradation due to population growth ?

I heard a friend of ours (she is a veterinarian) say that, on some species, homosexuality rises when the resources needed to maintain the horde are depleting. Perhaps that's the reason why the gays are on the rise.
This is of course a very short reasoning and it is not proven but...

I find the idea of gays one day saving the world an incredibly funny ironic joke! Smile

You can thank me later. Cool

I am 100% certain that I am wrong about something I am certain about right now. Because even if everything I stand for turns out to be completely true, I was still wrong about being wrong.

You mean you are going to save the world by yourself, with no help at all? Tongue
