thats true and ya a acre of hemp can replace 4 acres of trees plus it will mend the soil...no need for spraying crops and its one of the strongest fibers ever.
But since it is such a usefull plant,,,and can put so many people out in the cold dont expect it anytime soon ,,,, you know it can be used for ...fuel....food..[ seeds and oil] not to mention you can make a MDF that is stronger ! woot for hemp
