I really feel like we're between a rock and a hard place on this problem. Reliance on petroleum is so destructive -- e.g., oil spills such as the one in the Gulf of Mexico this year and the one in the Timor Sea off the coast of Australia last year, tar sands mining in Canada, bursting pipelines (breaks my heart to think of Nigeria) -- and as accessible sources are used up it will only get worse. But biofuels are not the answer either. I live in Illinois and the vast majority of the landscape is being ruined by cornfields (some for cattle feed, some for biofuel, very little for direct human consumption)...and I won't even go into the wind farms taking over everything! This is equally bad for the birds! So what's the answer? I don't know! I try to ride my bike as much as possible but few people I know are willing/and or able to reduce how much they drive. Some have to commute just for the job, so I sympathize. We need to figure something out, but it will have to make it easier/more enticing for people to do without cars. (I lived in Morocco for two years and did not have a car so it can be done! But in America, at least central Illinois, almost impossible.)
