Seriously - to think that we're the only species that would wipe out another because we eat them, or because we build houses, or develop ranchland...is absurd. As long as food is available, some animals will eat until they die.
My point is, if humans were to vacate the planet today and leave the other animals to their own devices, there would still be extinctions. I don't think we should totally disregard responsible behavior and go killing every animal in sight, but I think a little thought is in order when we're paranoid about a species of fly vanishing from our world forever.
After all, if it evolved from something, won't it eventually come back (and no, I'm not a foe of evolution)?
