The End of Cats: An Interview With the New Zealand Economist Calling to Eliminate All Kitties - Derek Thompson - The Atlantic: Because we have virtually no obligations on cat owners (bit like you guys with your guns) and so people own them, abandon them, and generally take no responsibility for the unintended consequences of their actions. The most oft-heard and erroneous utterance we get here from cat owners is, "Oh but my pussy only kills rats and mice, he'd never harm a native bird." As you can see this denial verges on explicit stupidity.I believe circumstances are similar here in CA. Human activities are probably the greatest evolutionary pressure(s) ever.
Unintended consequences, indeed.
(Note: I appreciate he's making an economic proposition here, but I don't think that alone is a sufficient indictment of it.)
