Mr. Benson, here is what I see in Wikipedia regarding jatropha, "Goldman Sachs <http://en.wikipedia.org/wiki/Goldman_Sachs> recently cited /Jatropha curcas <http://en.wikipedia.org/wiki/Jatropha_curcas>/ as one of the best candidates for future biodiesel production.^[4] <http://en.wikipedia.org/wiki/Jatropha_oil#cite_note-3> However, despite its abundance and use as an oil and reclamation <http://en.wikipedia.org/wiki/Land_reclamation> plant, none of the /Jatropha/ species has been properly domesticated <http://en.wikipedia.org/wiki/Domestication> and, as a result, its productivity is variable, and the long-term impact of its large-scale use on soil quality and the environment is unknown.^[5] <http://en.wikipedia.org/wiki/Jatropha_oil#cite_note-Fairless-4> However, because jatropha can grow in harsh climates, it can be planted in areas where it won't compete for resources needed to grow food.^[6] <http://en.wikipedia.org/wiki/Jatropha_oil#cite_note-5>"the emphasis is my own.
