In a part of the new Seminar About Long Term Thinking, “Deep Optimism,” Matt Ridley talks about the ethics of buying local. Apparently, the amount of fuel used to ship an object to a store in the US from a factory in China is on average ten times smaller than the fuel you use to drive to the store to buy it. There are other factors in the ethics of buying local, of course, but it may be that how you get to the store is a more important decision than how far away the object you want was made or grown. It makes me wonder where buying mail-order falls in terms of fuel efficiency. Will we see Amazon asking us to buy from them to protect the planet?
