In my defense, I did just say "amazon very vulnerable", not "gone
tomorrow!". But I was admittedly more upset by the journalism than the
report it described (thanks for that link, and thanks to WH for the very
nice web site).

This could be true, and I actually have no problem with reporting
scientist's personal, yet expert, concerns. I would prefer however if it
were clearly identified as such, and not implied that whatever study in
question clearly supports them.

I thought of that too, and it seems a very likely significant factor. More
so now that I read how deep the soil is. I had always been under the
impression that amazonian soils were very shallow.
