The laws of diminnishing returns

[jstalin]

The more concentrated a resource, the less energy it takes to make use of it; and the less concentrated a resource, the more energy it takes. Consequently, the richest deposits of any resource are used first, and then lower-grade deposits are exploited, at an ever-increasing cost. As high-grade mineral ores are worked out, more and more energy is needed to mine and refine lower-grade ores. As oldgrowth timber vanishes, more and more energy is necessary to make lumber and paper out of smaller trees. As the world's fisheries are worked out, it takes more and more energy to find and catch the remaining fish. And as the world's topsoil is lost -- at a rate of 75 billion tons a year (Myers, 1993, p. 37) -- more and more energy must be used to compensate for the diminished fertility of remaining agricultural land.

and the main thing (energy in oil) we're running out of fast
