Does the human race------ Have a goal, other than an ever easier lifestyle, do you agree that we will never all be equally comfortable, do you agree that the Earth does not have the resources to make it so? In another thread the ideal population for Earth was guessed to be 2 billion, we are way over that. Eventually we will need more land than the Earth has, so should we be looking to populate other planets with some urgency? Edit. http://www.ecofuture.org/pop/rpts/mccluney_maxpop.html When environmentalists say that the world is overpopulated, they mean that the environmental consequences of the excessively high human population are destroying the biosphere--the Earth's life-support system. This leads to the question of what these environmental consequences are, and the related question of how many people can the Earth really support. As we'll see in this article, the question cannot be answered without offering another-- "What kind of world do you want?"Finally, there's another, more fundamental, question--"What kind of worlds are possible?"
