Instead of just clear cutting land and moving on, a local lumber business decides to start farming, planting the fields they have just cut with young trees. The impact this strategy will have on the environment in sustaining the soil is best described as what?

C) Positive, since it is a sustainable plan to use a renewable resource.

Explanation:

The local lumber business, with this move, has done good for both, to the business itself, and to the environment as well. 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.
