Reading Ashton Crusher's comment above, I find it disheartening that everyone believes Pimental and the Cornell Study without questioning it, it just prooves that people will believe anything said by anyone. I clbuttify Pimental as an "anyone". Below, I have reposted a comment I made about this study that I had made on another newsgroup...
The two researchers behind this Cornell-Berkeley study, David Pimentel and Tad Patzek, need to answer a lot of credibility questions regarding their latest report against biofuels. Besides the fact that much of their studies in the 70s were sponsored by Exxon, I question the credibilty of both researchers. I cut and pasted the following from this website: ata-ag-st...
"Pimentel is an insect ecologist in the department of entomology at Cornell University. He is one of the scientists who in 2000 famously found that milkweed leaves dusted with heavy concentrations of Bt corn pollen were toxic to Monarch butterfly larvae. Tad W. Patzek is a civil and environmental engineer at the University of California at Berkeley.
"Corzine says Patzek was a longtime employee of Shell Oil Company and founder of the UC Oil Consortium, which has counted BP, Chevron USA, Mobil USA, Shell and Unocal among its members. He also is a member of the Society of Petroleum Engineers."
Personally, I find the findings of Pimentel and Patzek biased and laughable.
