Al Bartlett is a physicist and in this video he talks about population growth and peak oil. His talk is succinct, to the point, and very easy to follow. He says that politicians, journalists, and lay people do not understand the exponential function and how the population doubles about every 30 years. This is called the doubling time and Al Bartlett says that in the next 30 years will we use more oil than as ever been dragged out of the ground since mineral oil was first discovered as as fuel way back in the 18th Century.
This is corporate capitalism going full pelt and some people put the blame for this on the banking industry with its compound interest which takes ever wealth more from the economy. Obviously this can't carry on. But we also rely on oil for plastics and synthetic rubber which are extremely important in our modern lifestyle too. Fortunately solar and wind power is ready to make a breakthrough although many in the West tried to foil this development to keep us addicted to oil, which of course had a knock on effect in the Middle East.
