Dear Colleagues:
I wrote this recently and thought it might be useful for some of you to read. Feel free to challenge my reasoning if you think I've gone off the reservation.
What I have been studying suggests that human impact on ecosystem function, while extremely complex can be understood by everyone. Indeed it must be understood by everyone if we as humanity, are going to change what can now be seen to be a predictable and probable catastrophic outcome.
I have learned that in science we must not assume things to be true, they must be proven.
