Yes, using animals in this was in unethical and yes animals have emotions. But I love meat so much I just can't seem to care. I mean I feel evolution made us humans evolve into beings that _can_ take advantage of all the tools and so why shouldn't we. Yes, this means I am ignoring the fact that the animals are being tortured. Putting it that way sounds bad but too bad, we step on ants every day as well. It's just where nature has gotten us.
In fact, if you mention the greenhouse effect and all, I think we're destroying our own habitat. In a few hundred years, might make humans extinct. But that's about it. The "Planet" is not being destroyed. It's us who are in danger. We brought it on us, we'll have to face it.
That was my rant and trust me, if you meet me you won't think I have such harsh views. But I wonder if anyone else thinks the same way or would like to discuss this.
