"Fenner says the real trouble is the population explosion and 'unbridled consumption',"-The Australian
This man claims to be a scientist? I say he is probably feeling his life/career dwindling down and thus doomsday shouting. He has nothing to loose- if he were right, then people would say, "Wow! He was right!" If he is wrong, what would it matter? He wouldn't be around to have his credibility hurt. It bothers me that the media can show such naivety towards real science, or if they know better, that they would go through such lengths for sensationalism.
It is elementary population dynamics that organisms show exponential growth until reach the capacity of their resources:

This happens with pretty much every type of organism on the planet and we are not much different. When the carrying capacity is reached, the population levels off at a plateau. This is a graph for some random sheep population, but quick research of published documents will show that it is true for any animal.

I can see that this might cause different effects when this happens the human race, since we are heavily armed and eager to compete with each other using over bearing means of force. However, we are also known to work together quite well and show ingenuity when it comes to resource management. There isn't a question that we will eventually feel some kind of pressure for resources, I think it mostly depends what "mood" we are in as a species that will decide how we react to it. So I agree with many people on here saying that there
could be some kind of war,
eventually. But there is nothing certain about it, and where he gets this 100 year time limit is beyond me. It's a shot in the dark, I think it has less than 50% chance of being true, as in it is more wrong than correct.
