Just do the arithmetic. The amount of carbon we have emitted has
increased its proportion (there are good records of this) in the
atmosphere enough to alter its retention of the sun's heat
significantly. Sadly, we *are* important.

No. But I do see the connerction between "we're emiting loads of
stuff" and "we can now confirm the bad effect we are having by doing
so".

Many of these reports are actually the result of recent, independent
studies. Although I do own a copy of Lomborg's "The Sceptical
Environmentalist", which I commend generally.

Now there's a nice broad generalisation. "One study was found to be
bad, so all of them are bad". Come on!

Many do.
"Open mind". Hmm. Sometimes when I open a cupboard door, everything
inside just falls out, leaving the shelves bare.

By no longer being able to find any member of them? In all or a major
part of their former range?
Do you believe that there are still passenger pigeons and dodos, and
evil environmentalists are just hoodwinking us into believing they are
extinct?
Do you believe that the Newfoundland fishers conspired to stop fishing
the Grand Banks, just to fool us, and there is actually still a huge
cod population out there?

If the current population of species A needs x ha to survive, and of
species B y ha, and the total area is greater than x + y, then both
populations will survive. If the population of B increases so that it
needs z ha, and the total area is less than x + z, then the population
of A will decline. Not hard to understand, I think.

Those "arbitrary" taxes are actually to cover the externalities your
acquisition of the plate would impose on the environment, but which
you wouldn't otherwise be paying for. All they mean is you will no
longer be getting something for nothing. If you are paying the *real*
cost of the plate, I don't care how much you buy. But if you want me
to pay part of that cost, through externalities, I will object.

If there were fewer of them, they would come into conflict less.
However, I (and they, I am sure) am somewhat unhappy about the method
currently being applied to reduce their numbers.

Much of today's desert was formerly green. A principal cause of the
desertification has been man.

Have you ever *looked* at Scotland? Where there used to be forests,
there are now bald hillsides, kept that way by the disastrous use of
the territory to raise sheep. I think the Herdwick (sp?) is one of
the very few species I wouldn't mind seeing become extinct.

Who said anything about control? Assumptions, assumptions! I
actually favour persuasion, rather than coercion.
