Well, not exactly. While a crocodile is driven more or less purely by it's need to survive - I don't believe crocs kill gazelles to make nice coats for themselves - we kill or "exploit" animals for reasons not even remotely related to survival.We "exploit" animals for our benefit in the same way a crocodile "exploits" a gazelle for their benefit.
This is not to say some other animals don't also exhibit some form of this - playing with their food before killing it, for example - but humans are pretty much the sole animals on this planet that kill for pleasure or for convenience.
Of course, I'm no animal rights activist, and frankly, I don't even really feel sorry for caged chickens. Sure, I'd like for all chickens to grow up naturally, live long lives, raise their chicks, and die happy birds, but I also don't want to listen to my kids bitch about having to eat tofu nuggets.
And don't think for a second that if chickens had evolved into the dominant species on earth there wouldn't be restaurants serving human nuggets. We won the evolutionary lottery. Chickens (cows, pigs, bees, rabbits, dogs, cats,...) lost. Tough nuts to them.
Now pass the honey mustard sauce.
