ecogeek weighs in on the topic of walking is worse than driving. Just as I suspected, the concept is fatally flawed.
'Someone took the results of a scientific study on how inefficient our food production system is, did some really bad math, and then found themselves a glorious headline that would send shock waves throughout the blogosphere. You could call it sensationalism...I just call it evil.'
I am not so up on the math part and thank them for pointing this out. What I thought were some well-argued points by the original author, turn out to be pure junk science.
