***********************************************
It's wonderful to read permaculture discussions about "invasives", e.g. about
kudzu, filled with observations, openness and humor.
"Invasives" seems to be a hot topic. I wonder if would be a good theme for an
upcoming issue of Permaculture Activist? Permaculturalists might be well
placed to talk about invasives since they are commited to:
1) Observation of the natural world
2) Human intervention in the form of gardening, landscape design, etc.
3) Environmentalism and sustainability
Such an issue might be of broad interest to the outside world.
