Turpentine (C10H16) is produced through the distillation of tree resin. Humans could reduce the impact of turpentine production on forests by doing all of the following EXCEPT–
improving the distillation process to increase the amount of turpentine produced from tree resin.
finding a source, other than trees, that can be distilled to produce turpentine.
besides using the resin for turpentine, using the other parts of the tree for other purposes.
cultivating trees on land set aside specifically for producing trees for turpentine.
