Steve, in the purest sense, I understand what you are saying. However, humanity is accelerating extinctions (and as a consequence, accelerating it's own demise) because of its overblown sense of self-importance. We have moved well beyond reasonable, balanced and sustainable participation in the world biota and are turning the world's lands and seas into deserts.
Richard Ross, one of the first to write a book on python husbandry, and a pediatrician professionally, suggested that the huge improvements in pediatric medicine in the last hundred years basically writes a death warrant for thousands of species. Obviously it is not politically correct to say this is a bad thing, (who would want to compromise the health of their child if means can be found to avoid disease or death?) but the inevitable consequence is that the earth is becoming a monoculture. He has a photo of a huge fire burning in the Brazilian rainforest, and describes it, sadly, as a 'biological funeral pyre' - the same things are happening here in Australia.
You mention god several times in you post Steve - I don't believe in 'god', so I won't sit back and see what we humans are doing without at least commenting that, with our vast intellect and perceptive abilities, it is our responsibility and within our control to do something about it. I can't handball the problem to some 'higher authority" and say that what is happening is what was meant to be. The introduction of Cane Toads into Oz is not something I will ever accept as a 'natural progression into extinction' for Australian fauna.
