I don’t and it won’t. The world will come to an end for certain in 6.5 billion years when the fuel in the sun runs out – we have 4 billion years to develop a plan-B – given humans have been around for 200,000 years and gone quite some way technology-wise then there is some hope.
I certainly agree that issues with an increasing world population (it has doubled in 40 years) and diminishing resources will be a problem but it will after 2012….
