Earth’s surface is mostly water. However, only a small amount of water on Earth is clean freshwater. Why is it important to maintain water quality? A. to keep water from evaporating
B. to keep the ocean levels from lowering
C. to keep the polar ice caps from melting
D. to keep water from becoming a nonrenewable resource

all fossil fuels are nonrenewable, so think coal, gasoline, things that we will eventually run out of. all fossil fuels are nonrenewable resources, but not all nonrenewable recourses are fossil fuels. these resources are not being renewed as fast as we are using them. i hope this considering there weren't any answer choices.
