But surely the MOST powerful species should survive at the expense of EVERY
OTHER species, and have sole access to all resources available for life. This
necessarily means destruction of other species.

This is a good point, and unforunately the answer is rather open to abuse,
which is perhaps that in modern society there are a higher proportion of
aggressive genes, better at SURVIVAL (but nothing else) than those in less
developed cultures. Still as I pointed out, being better at survival is no
qualitative evalution, and a species would probably be better off happy than
trying simply to outsurvive all others.

This is because no species as yet completely severed its dependence on other
species. What I am interested in is what will happen when, inevitably, this

Expansian is a destructive process for all other species, to be sure, but
it is not destructive for the species doing the expanding. Genes cannot
possibly evolved to look after other species, EXCEPT if those other species
are necessary for our own survival.

It harms our survival ONLY because there are more other species competing
for the same resources. Biodiversity may be good for the ecosystem but it
cannot be good for the *survival prospects* of a species that does not require
other species to survive.

This I agree with, and is one of our other tendencies to go against natural
law that is evolutionary quite interesting. But I still hold that nature's
laws are essentially destructive for every other species but the hypothetical 
one that does not require them.

I am not suggesting that biodiversity is not natural, it is natural so long
as species depend on other species for survival. Once this is no longer the
case for a single species, biodiversity is not natural.

a) not good or bad = no point? I don't see the connection, given I mean 'good'
or 'bad' in terms of human morals.
b) we should turn on it because we are not happy with the way evolution has
created us, understandably so

I agree entirely.

Thanks for the comments!

..yes I *do* know how to write signature files, but I just can't be
bothered really...
