I think wildlife major hubby says "it's natural" to help him with the whole idea. And in a way it is - no, cars aren't "natural" but they are a part of the world, and they're a "fatality factor" that some critters are going to succumb to. (Where do you draw the line? Is a beaver dam really "natural?" It's something built for an organism's own purpose. Yea, it's a reach, but ...)

I do tend to (also having a degree in wildlife) say "oh, it's a bug, it's r-selected anyway." Which is to say, the organism has tons of offspring and relatively few survive; death is more likely than life in the normal course of things. The k-selected critters give me a moment of sadness... (the ones where , generally, more organism energy and time are invested in the individual and a higher percentage of 'em s;urvive). And we're pre-programmed to sympathize with baby things.
