haha, I should! I was going to go for "it looks much prettier without them"...
That's not a bad angle, either. There's a term, "charismatic megafauna", that's used to describe how certain species are singled out for "rescuing" because people like them. For example, which animal would you rather fight to save from extinction when its marshy habitat is paved over: a beautiful bird, or a pesky mosquito? Same thing goes for the decay microorganisms.
