Sure in the course of things after say 13 billion more years this universe will expand enough that entropy will be a problem for whatever sentient creatures that exist then, but until then, the universe is plenty dense enough to allow for life to flourish.. Suns compress matter and burn the lighter elements releasing enormous amounts of energy, more than any terrestrial civilization will ever need or use.. Humanity has always overcome supposed limiting factors on its growth by utilizing its intellect. [color="#1C2837"]Malthusian ideas based upon the study of non-intelligent organic growth, ie rats and bacteria doesn't extrapolate to humans. Sure there are indeed hard limits human growth and habitability, but we'e not run into it yet. Look at the human population growth curve according to most [color="#1C2837"]Malthusian adherents we should have eaten ourselves to death somewhere around the 70's given their projection of food vs people, but I guess they didn't account for the green revolution, the increased efficiency of farming practices nor bio-technology..

[color="#1C2837"]Also if you examine the population growth curve not of the entire world but a single industrialized nation you'll see all of them exhibit the similar patterns, a period of exponential growth, then leveling off due to social dynamics, ie cost of living forces people to have less children which slows population growth in developed countries. Most of the developed countries have negative birth rates ie more people dying than being replaced.. So populations don't need to collapse for humans to stabilize because humans have put themselves apart from the natural order when they started to utilize their intellect..

[color="#1C2837"]China, one of the worlds largest populations, already is skirting the edge with respects to birth rates. Its alittle less than replacement levels, and this is repeating all over the world, humans for whatever reason are hitting a social limiter on their growth, maybe its pollution or some feedback loop with affluence.. Who knows..

Malthusian proponents would disagree. As our technology has increased our agricultural output, it has balanced the equation from the other end.

The cost of living in developing countries is higher w/ regards to income than it is in developed, affluent ones.

To think that we are no longer part of natural order is absurd. The Illusion of control is shattered instantly when nature deems so. Look at indonesia, new orleans, BP's deep water drilling, and currently Australia with the floods and fire.
