Let me preface this by saying that what occurs by evolution or in the wild does not justify what action we take by any means. However, watching a few wildlife shows has made me rather melancholic about the requirement of suffering and death. I am not necessarily saying that we should intervene, but is it only me who get depressed at the idea that suffering and death is REQUIRED for ecosystems to function? Each individual species has a preference to avoid suffering and to continue living. No species submisses to a predator, even though a certain statistic must in order to avoid overpopulation. I am aware that the suffering that would arise if ecological issues occured is greater than suffering at present, but it seems strange to me that our species and our pets can live free of threat, whilst everything else cannot. Again, I am not saying "well it's gonna happen anyway, so why don't we do it" by any means, but it does make our efforts seem futile.
