Colin Campbell is a founder of the Association for the Study of Peak Oil and Gas (ASPO). In this interview he talks about Peak Oil (he thinks it occurred in 2008), the current financial situation, his belief that a second, more serious financial collapse lies ahead, and whether the right steps are being taken. He is not a doomer as such, but I don't come away feeling as though we'll be able to slow down the slide or manage it very successfully.
I will be 100 years old in 2053 if I live that long. But based on the following quote I don't know that I want to, and I certainly expect life to get more "interesting" along the way:
Today's oil supply support 6.7 billion people, but by 2050 the supply will be enough to support no more than about 2.5 billion in their present way of life. So the challenges of using less and finding other energy sources is great.
