    Aug 21 2012: WE DO NOT KNOW. This should cause us to be very careful and very cautious.

    We do not know which species WE currently depend on.

    We do not know which species we WILL depend on in the future.

    We do not know which species could , potentially, be extremely valuable to us in the future.

    We do not know what species are out there. Biologists guestimate that there could be a trillion unknown species.

    We do not know how species relate to each other and depend on each other.

    Of all there is to know about life on this planet, we actually know next to nothing. Instead of taking the cautious path we have used the magnificence of our ignorance as a justification to pillage our planet.

    Perhaps, in the not extremely distant future, one of the last books written will meticulously trace our coming extinction back to our carelessly allowing some species of bacteria to go the way of the dodo bird. The authors will be so proud of their accomplishment.

      Aug 21 2012: Let's hope we don't lose some vital bacteria or fungus because we spend all our time trying to save big furry cute animals. The great irony of most conservation efforts is the tendency to concentrate on animals that are a long way down their food chain when the simple producers and their symbiotes are what holds the whole thing up.
