But if people didn't keep pets, (it's a fairly recent phenomenon), and all those critters had to compete/survive in the wild, there would be a lot fewer and they would be part of the balance. The idea that cat and dog poop return to the earth, nurturing plants, is ludicrous. More often it, mixed with kitty litter or wrapped in plastic, goes in the trash for Energy intensive disposal. Cars and concrete are low hanging fruit, ya gotta think green here.
At least that's what the militant Greenies are telling me.
