The Virtues of Rice and Strawberry Shortcake

From a post on Slate about the amount of fertilizer and pesticide used by different foods:

White rice came out the big winner here, returning more than 2 million calories per pound of pesticide used and 82,000 calories per pound of phosphate. Onions and sweet corn ranked nearly as efficient as rice when it came to pesticide, but were only so-so in terms of fertilizer; the opposite was true for oranges and apples. Lingering at the bottom of both lists were strawberries, which returned just 121,000 calories per pound of pesticide, and 5,300 per pound of fertilizer.
