Gas From Rats?

We found Sweden's attempts to make use of its "urban rabbit problem" (that's really what they call the masses of former pet rabbits now roaming Stockholm's parks) by turning them into heating oil a fascinating proposition. Now, we were curious as to what other "pests" could serve the same purpose. It wasn't too long ago, for example, we made the case for eating more nutria, a move that Louisiana would greatly appreciate. So we took our idea of using rats to the experts--in New York City, of course. You can find out the result in our latest "Minute of Your Time."
