In the future, we all eat bugs:

...In the future, a bug-rich diet is all but unavoidable if we don't want to continue polluting our ever more overpopulated planet or end up eating soylent green. As (William) Lyons (of Ohio State University) points out, " If the U.S. Food and Drug Administration would relax the limit for insects and their parts (double the allowance) in food crops, U.S. farmers could significantly apply less pesticide each year." He also adds that the insects we do eat and don't know about actually boost the nutrition content of the foods they fall into. Which would you rather have less protein or less DDT?
