question 10 of 10
when would a forest be sustainable?
a. when demand exceeds supply
b. when supply and demand are both zero
c. when demand increases while supply stays the same
d. when supply exceeds demand

Explanation:

A sustainable forest means that the forest resources can be continuously used. When supply exceeds demand, it indicates that the forest has enough resources to meet the current needs and can also maintain its own ecological balance and renewal ability for future use. If demand exceeds supply (A), the forest resources will be over - exploited and cannot be sustainable. If supply and demand are both zero (B), it is an extreme and unrealistic situation. When demand increases while supply stays the same (C), it will also lead to resource depletion.

Answer:

D. When supply exceeds demand
