I found this article fascinating.
For all of you too lazy to read the article (Greg, I'm looking at you), it's about a company in California that has figured out a way to genetically modify bacteria so that they feed on agricultural waste and then excrete crude oil.
The answer to the impending energy crisis is not offshore drilling, nuclear power or some other renewable energy source. The answer, ladies and gentlemen, is bug shit.
I love it.
As I was reading the article, I was thinking two things:
(1) I was thinking about possible Hollywood-style disaster movies hinging on genetically-altered mutant bugs, kind of like a science gone horribly wrong thing or a futuristic big brothery thing.
(2) I was trying to decide what useful natural resource I would like to poo if given the choice.
So I'll open up the comments section. If you, reader, could excrete any useful substance, what would it be?
