Walk through the "back 40" with scissors. Cure cancer & make money.
I like the idea of using small woodlots within a county or township to as a sustainable source of revenue by harvesting little bits of different plants. For example, selling the trimmings of your hemlock trees to a biotech firm who will use them to create anticancer drugs like paclitaxel (a.k.a. taxol™). posted on http://jgarlough.blogspot.com/
