Peter Singer – Famous philospher
…and the idea that you can save fossil fuels by not transporting food long distances. This is a widespread belief, and of course it has some basis. Other things being equal, if your food is grown locally, you will save on fossil fuels. But other things are often not equal. California rice is produced using artificial irrigation and fertilizer that involves energy use. Bangladeshi rice takes advantage of the natural flooding of the rivers and doesn’t require artificial irrigation. It also doesn’t involve as much synthetic fertilizer because the rivers wash down nutrients, so it’s significantly less energy intensive to produce. Now, it’s then shipped across the world, but shipping is an extremely fuel-efficient form of transport. You can ship something 10,000 miles for the same amount of fuel necessary to truck it 1,000 miles. So if you’re getting your rice shipped to San Francisco from Bangladesh, fewer fossil fuels were used to get it there than if you bought it in California.

We’re the richest country in the world, so by buying papayas here in Colorado I always figured it was a help to third worlders as they work to step up to 2nd and 1st world. I hadn’t really thought that by pressuring folks to “buy local” you’re also pressuring women/mothers (and of course men/fathers) to “work harder”! Spend even more time picking out groceries!
