(emphasis is on 'living' as this keeps the
> oxygen-ethylene cycles going).

In our PC course in Hawaii in 1992  Lea Harrison gave us a handout about the
ethylene cycle, which I think is one of the most devastating scientific
proofs of the  detrimental effects of plowing and  mechanized agriculture in
general ( by accelerating the metabolic rates.)

Unfortunately, I no longer find the handout she gave us, and no longer
remember the cycle by heart ( although I did so for some time, am  no longer
so sure about it...)

Does someone have it on their computer ?  I would most appreciate this
help..
