such approach. It has been stated by the International Energy Forum that at present, only ethanol produced from sugarcane in Brazil is a viable option when considering the GHG balance, and other aspects as well. Ethanol produced from sugarcane has a competitive advantage over maize and corn feedstock, because the sugars can be directly diverted into ethanol. Also, unlike wheat, sugarcane industrial processing is often powered by sugarcane's by-product, bagasse. The main problem that overshadows the assessment of biofuels GHG emissions is the various advantages and disadvantages of all the different biofuels. As pointed out by Scharlemann and Laurnce (2008), there is no "common currency" for comparing biofuels, as each biofuel has certain benefits and costs. The article explains a study (Zah et al.,2007), where, on assessing biofuels against GHG and all other environmental costs, it was found that most biofuels reduce greenhouse gas emissions, but have other severe environmental costs
"This was a real one," says Jake. Afterward, Brett marvels at Romero's skill. She has watched everything, while Cohn has had difficulty dealing with the spectacle. Mike taunts him mercilessly for his weakness. Brett and Mike sit with Jake during the next bullfight. Romero works close to the bull, wearing him down slowly before he moves in for the kill. His suave and graceful performance delights everyone, including aficionados like Jake and Montoya. He utterly overshadows the other bullfighters, and his bullfighting gives the spectators "real emotion." Mike jokes afterward that Brett is falling in love with Romero, and he asks Jake to tell her that bullfighters beat their mothers. The following day Romero does not fight, and there is no bullfight scheduled the day after that. The action of the fiesta continues unabated, however.
