Leland, I agree with you. If take tractor to plow using oil and harvester to crop you will pay to work if your products go to burn.
   When I begin defending ethanol from sugar cane think about this as better option.
   But with carriage running we discover "dark brown sugar" and ""sugar cane syrup" as meals for human consumption using less energy to produce. 
  We make an course of home production of sugar cane products and its prices are three times higher than industrialized products. 
  With sugar cane bagasse we search how to use for cattle breeding trying to hydrolizes it.
   We get it using calcium hydroxide to spray and in three hours it becomes yellow avoiding fermentation remaining five days able to use.
   Is necessary to mix with some amount of green grass.
  Ethanol yields 14/1 from sugar cane and meat from sugar cane 17/1. 
  Ethanol is heavy investment and cattle breeding only need one bull and other cow.
  We are alert to use salicaceae plantations to make cellulosic ethanol because in Argentine is needed only from 100 to 250 dollars to make an platation from stacks. 
  The menace is with increasing prices of lands also forestry areas are useful to breed cattle in agroforestry use.
   Economic menace is worst because no environmental reasons can survive from this powerful force.Market. 
  Now we are studying with doctor Richard Haard how to produce meals and biofuels in wetlands. Cattails not only clean waste water from sewage also gives polen from its "tail" , cellulose on stem and starch in it roots.
   We are sended to water for produce sustainable products.
   Algae is another option not only for fuels also fishes feed.
  Debate is only beginning.
  Regards, Ben

  Science Magazine, AAAS publication:
Most prior studies have found that substituting biofuels for gasoline will 
reduce greenhouse gases because biofuels sequester carbon through the growth of 
the feedstock. These analyses have failed to count the carbon emissions that 
occur as farmers worldwide respond to higher prices and convert forest and 
grassland to new cropland to replace the grain (or cropland) diverted to 
biofuels. By using a worldwide agricultural model to estimate emissions from land-use 
change, we found that corn-based ethanol, instead of producing a 20% savings, 
nearly doubles greenhouse emissions over 30 years and increases greenhouse 
gases for 167 years. Biofuels from switchgrass, if grown on U.S. corn lands, 
increase emissions by 50%. This result raises concerns about large biofuel 
mandates and highlights the value of using waste products.
