7. What is a renewable resource?
What is a nonrenewable resource?


Renewable is either always available
or is naturally replaced in a
reasonable amount of time.
Nonrenewable is not replaced in a
useful time frame.
8. Describe how environmental
decisions are made.

You first have to weigh out the
ecological and economical costs and
benefits. Then, make a decision.
9. How does the idea of a sustainable
yield pertain to forestry and fisheries?



Both forests and fisheries are living
resources that need to be around for our
future.
In a sustainable forest after trees are
harvested, young trees are planted. Also
selective cutting can be used to ensure
the future supply.
Fisheries can set limits, change fishing
methods, use aquacultures, or find new
resources in order to provide a
sustainable yield.
10. Describe one way that overfishing
can be prevented.


Use aquacultures
Set fishing limits
11. Why is gene pool diversity
important to the survival of a species?

Species with diverse gene pools are
better able to adapt to changes in
the environment.
12. Explain how habitat destruction
affects species.

Species loose the places to find food
and shelter. If they cannot find a
substitute niche, the will either have
to move or die out.
13. Describe the importance of
biodiversity to drug research,

Biodiversity helps prevent species
from becoming extinct and we need
the wild species to discover new
medicines.
