It's the root of many of this worlds problems.
Is there too little ariable lands in the world, or too many people?
Is doing everything we can do to continually extend average life span good for the earth? Is modern medicine solving problems on a micro level, while hurting things on a macro level?
Are epidemics like aids just natures way of trying to contol its population?
Quality of life is harden to sustain for a million people than 500000 people. It's very simple math. The more people you have, the more things have to be divided.
As a world, we really need to level off our population or start decreasing it, because this world just can't handle continues expansion. Simple math.
Are humans naturally aggressive and territorial to help control the earths population? Are wars in-evidable (history says they are) and in a way, necessary?
Has medicine advanced too far? If everyone lives forever (significantly longer than in the past), and people don't slow down in the making babies department, this world will be overflowing soon.
Any ideas on what the people of the earth could do?
