If humans are nothing more than the product of natural forces (such as natural selection) then how can anything they do be anything unnatural? There's a real problem with the logic when humans are said to be constrained by ethical behavior, but are themselves sourced in a process where there is no such thing as ethics.
I didn't mean humans have no responisbility, only that it's not so simple. Species have been going extinct for as long has life has existed. Zero extinction as a human goal is just silly.
Not possible, but it's easy to understand why the proponents are pushing "Survival of the Weakest"
I don't disagree, but we can do better in reducing our very heavy footprint. "Natural Selection" doesn't include what happens in extreme man-made environments such as strip mines and monocultures that run for hundreds of square miles.
Hello: I agree with Ron. For example, the non-government organizations in the Bearing Sea are giving up there fisher studies with the claims that global warming was killing off fish populations after three years of colder weather (http://www.nature.com/news/2010/101103/full/468026a.html). It was found the fish were migrating to warmer waters and getting eaten by other species, exactly what Ron was talking about. Let nature do its thing and that includes man.
Well said Ron
Zero extinction can only be achieved if natural selection is eliminated from the world. Even "Creationists" recognize that natural selection is an active process, which inevitably leads to the extinction of species that fail to adapt to changing environmental factors, whether caused by man or natural forces.
