That's a fair statement for todays conditions, but not going forward. Already our farmland is being converted from food sources to non-food product sources. Soy beans to diesel fuel, corn being used to make plastics . . . our main farmlands will become a battleground between producing enough food for a growing population and satisfying our desire to have unlimited cheap material resources.

The major engineering challenges for the future will be related to agriculture -- genetic engineering to squeeze greater yields per acre, hydrologic engineering to allow us to crop currently non-arable land, and bioengineering to create microorganisms that will turn any marginal bioresidue into useful product.

It doesn't matter when the price of oil becomes "too" high, it'll still take 3 generations before the population weans itself off the excess energy we think we need.
