> This reeks of naturalistic fallacy. Humans are bad because we exploit animals. Yet, humans are animals, and this is what animals do given the chance. We don't need an excuse.

It's exactly because we can introspect and consider the ethical state of things, that means that we should. The fact that you can think and reason about the fact that you're stealing from someone else, or otherwise harming something else, the fact that you are (hopefully) intelligent enough to think of a different way, means that you have a moral duty to be better than that.
You argue that I succumb to the naturalistic fallacy, and yet you are the one doing so. You argue that we do not need an excuse for our behaviour because we are animals, and it is natural for animals to exploit other animals.
In addition to that grave error, you're also making a complete false equivalency in equating "not using a random bear as a test pilot" with "abandoning all progress and becoming an agrarian society".
