Why does everyone seemed to think that because something is natural that it's necessarily “good”? For all of its “naturalness”, nature can be very cruel and indifferent.
But what’s even more amusing is the idea that we humans should care about what’s “natural”. I like artificiality! And history has shown that humans seem to thrive under conditions which have been customized to suit our needs. In fact, we practically demand that we live a largely fabricated existence (just look at what we’re doing right now, lol). I agree that nature does have its merits and we must work with it to a certain extent. But just as its can be very beautiful, it can also be harsh and uncomfortable. Love-of-all-things-natural is one of those things that people preach about more than they practice. This tells me that it sounds good in theory, but really isn’t the most preferable choice in practice (notice that when it comes to engaging in natural selection, most people suddenly don’t want to side with the “natural” thing anymore).
It’s a mistake to assume that natural = good.
