Instead of clear-cutting land and moving on, a local lumber business decides to start farming trees: cutting some of the trees and planting the fields they have just cut with saplings. compared to the old method of clear-cutting, the impact this new strategy will have on the environment is best described as what? a) positive, since the lumber company will immediately make more money. b) negative, since it is destroying much of the environment. c) positive, since it is a sustainable plan to use a renewable resource. d) negative, since it is a sustainable plan to use a renewable resource.

The correct answer is - C) Positive, since it is a sustainable plan to use a renewable resource.

The local lumber business, with this move, is doing good both, to the business itself, and to the environment. Since the amount of trees that will be cut, is immediately replaced with saplings that are taken care of, the lumber business is creating a sustainable business for the future, and also it is creating a renewable resource. The environment will also benefit from this, because the lumber business will only use certain amount of wooded area because it will have new wood constantly on the same area it is using, thus they will not have the need to spread out on a larger area and destroy the environment.
