Both of those statements are blatantly false.

We could probably double the population, but Earth is full *enough* by
any reasonable standard. We already use about 40% of the Earth's net
photosynthetic product, so we could double the population only if we are
willing to drive a large fraction of the Earth's species to extinction.

There's no basis for any of your statements.

If you have a better figure than 40%, and can back it up, I'd like to
see it. And if you think that the Earth isn't full enough yet - or that
wildlife can survive without habitat - then I guess you're just
unreasonable.
