It ...Each lb of lettuce provides about 75 calories. It takes 20 lbs of lettuce to provide 1500 calories so lets assume that 20 lbs of lettuce feeds one person for one day. If they were shipped by trucks, 20 lbs of lettuce would incur an extra 6,000 calories of transportation cost, which is about enough to grow 1 lb of lettuce. This means that we're talking about feeding 20 people with CA lettuce and 21 people with, say, VT lettuce with the same energy cost. Feeding 5% more people seems like a significant thing.<br /><br />Of course there are many problems with this calculation, with the first being that lettuce is very inefficient. I'd imagine this would work out very differently with grains and meat.Winghttp://www.winglmui.com/blog/noreply@blogger.com
