Thanks, CaftCandles and Stella, you saved me a lot of typing. Let's not forget all the gallons of petrochemicals that go into producing soybeans in the form of pesticides and fertilizers. In 50 years, I don't think society will have the luxury of burning their food for fuel or candles. The human race is overpopulating this planet and our present lifestyles will not be sustainable without massive amounts of energy. When the oil is gone, people will face a drastic change and burning candles will be for light, not fun, and could very well be back to rushlights dipped in fat. Remember, crude oil saved the whales.
