...well in my opinion that definition is not necessarily specist, unless
you do not consider humans as animals, as they obviously are.
James, would you please add some details to the problems with the part
interacting as a functional unit?

Julie makes a very good point. As part of a course I was teaching this
semester we covered the topic 'How to feed the world in 2050'. In Australia
at least this has become a topic of increasing interest as we face immense
challenges to our current agricultural systems from Climate Change impacts.
I would suggest that there are no world authorities for feeding 10
billion people. As it is, the green revolution came with cheap oil.
Food will only be harder to produce with less energy and more mouths to
feed. Certainly I agree with Beth that the big companies are in it for
the profit and
I would agree with Julie's post. CATIE is in Costa Rica works throughout Meso
and parts of South America on sustainable agriculture (the motto is Conserve
while Producing, produce while conserving) including work on sustainable

Dear dialogue participants:
Definitions imply authority, but are useful place-holders in the ongoing
dialogue we have labeled science, and the subset of intellectual enquiry
we call ecology. We accept such definitions provisionally, until a better
one comes along; it is always useful to

An interesting and evocative question and dilemma! I should really think on it
over time and reply in depth...but some thoughts of the top instead...
I agree with other repliers that the definition really does not exclude humans

Hi all,
I am using vegan to run a pca on forest structural variables (tree
density, basal area, average height, regeneration density) in R.
However, I could not find out how to extract factor loadings
(correlations of each variable with each pca axis).
Do anyone know how to do that?
David Pimentel comes to mind,
and I would strongly recommend to include some of the heroes of carbon
farmers, maybe Dr. Christine Jones from Australia ?
i do second tha motion that transwhatever companies do have their own agenda,
not necessarily a so called sustainable (I for one think that
