Cons
Disclaimer: These are not all cons, but considerations and realities about the work...Interesting hours, can be part-time nonetheless. Absolutely requires excellent interpersonal communications skills and willingness to put aside (sometimes) major rejection from community members who are confused about the work and have no idea who the stranger at their door is. Hard work, sometimes strenuous and dynamic work environment, but worth it if you believe in what the environmental movement needs to do to win major victories. Requires ability to be constantly flexible with yourself, peers, and members of the community. Leadership requires major personal investment into the work - IE longer hours, and more responsibility.
