It is not as bad as you might imagine - it's worse, and before you bury your heads in the sands of collective denial, please consider how it is coming about. The truth will set you free, but first it will probably make you ill.
We have had it too easy with cheap energy for a century and the cheap part is going to disappear. Quickly. Energy is the ubiquitous part of everything we consume, and liquid fuel is getting scarce.

We seem to have scientific prowess, but there's no time for self-congratulation. This time the solutions are the cause of a much bigger problem. Our current pursuit of growth and the elevation of human material wants above all else are the raison d'ętre of the problem. We promote consumption and ignore efficiency. We live as though there is no tomorrow, and the way we are going there probably won't be.
We might have just one last window of opportunity and it requires that we draw deeply on our resolve, think wisely and act purposefully. People will need to make unpleasant choices.

Furthermore, he advanced that population tended to grow in a geometric or compounding manner (1,2,4,8,16…), and that food linearly (1,2,3,4,5…).
