are resources that come from living trees. Lumber, pulp, and paper

Pulp, maple syrup, and nuts

Maple syrup, rubber, and nuts

Rubber, pulp, and paper

I would say that the answer is B pulp, maple syrup, and nuts

Explanation:

Lumber and paper require the death of the tree most of the time so the answer is not A or D. Making rubber from a living tree can result in the death or stunted growth of a tree. Maple syrup, nuts, and pulp can be obtained from a tree without killing it so B would be the best answer.

well, that's easy; the answer's c, "it reduces contamination of the water and substrate of the estuary."
