Re: E-M:/ Climate Change in Great Lakes



-------------------------------------------------------------------------
Enviro-Mich message from Barbara Jean Madsen <bjmadsen@biology.lsa.umich.edu>
-------------------------------------------------------------------------

The news about higher soybean yields may sound like one piece of good news
among all the bad, but research at the UM Biological Station has shown
that plants grown under elevated CO2 levels grow larger, but are less
nutritious.  So the soybean yields may be bigger, but you'd have to eat
more of them to get the same amount of nutrients--no real gain, and
perhaps even a net loss.
