1. Planet Earth is our only home for the time being. As global
populations grow and our resources dwindle, we should
worry more about the issues of SCARCITY AND CHOICE. All
parts of this question are part of the topic called Intro to
some key concepts of Economics.
i. There are 17 Rare Earth Elements. Pick any 5 of
them, and for EACH of the 5, explain in detail why
they are so critical to us. Use Google to look the
up.
Include in your answer:
a. what it used for,
b. why are those things so critical?
c. Where in the world the resource is
located.
d. And approximately how much is left.
e. For EACH of the 5, please explain 3
things we need to start doing today

to avoid running out of that
resource. It is very important that
you provide thorough and complete
explanations here.
b. The theory of rational behavior says that we humans
act in our own self-interest. Given our actual behavior
and the decisions we have made and are continuing
to make relative to the planet, please:
i. What does over-pumping of aquifers really
mean? Use Google to gather info.
ii. Is continued over-pumping of aquifers around the
world is in our best interest. If yes, explain why. If
no, explain why not.
iii. Explain how the continued over-pumping of
aquifers in America, China, and India, could
impact our ability to survive on the planet. This
will require that you find out what things these 3
nations have in common that are related to

aquifers. Connect the dots and explain how our
ability to survive on the planet could be
impacted by continued over pumping of
aquifers. Please provide plenty of detail here.
Google can help!

reality? If yes, then why. If no, the why not.
e. Marginal analysis is a decision-making tool.
i. Please define Marginal Cost
ii. Please define Marginal Benefit,

should do regarding the activity involved. Should
we do more of the activity, less of the activity, or
keep doing the same? Explain why in each case.

may also be of help here.

produced for us over the years. Make sure you provide
thorough explanations of why you believe these are
“good” things.
This is harder than it looks! Think carefully and be

will need to be very thorough in your
explanations. Don’t talk about pros and cons.

College unless otherwise noted.
thorough explanations of why you believe these are
“bad”.

flow of resources and expanding markets. Please

system when these two conditions are absent, and
explain why those things would happen.
