PPF of land for wild life and minerals. Help PLZZZ?

Question

I really need this, anyone knows? 10 easy points!!!

Depict the PPF of land for wildlife and minerals. Illustrate graphically and explain verbally the existence of a trade off between these 2 resources.

Thanks...

Answer 1

Surface of the world is 510'066'000 square kilometers, half of it is used for human living so rest can be used for wildlife or crystals. Substitution is possible - with this data is easy to draw production possibilities frontier.

Answer 2

Assuming you know how to already draw a PFF, this should be relatively easy.  On the y-axis should be "land for wildlife" and on the x-axis should be "land for minerals."  Draw various points on the PFF curve and label them "A," "B," "C," "D," etc.  No matter what point you're on along the curve, you must sacrifice either more of land for wildlife or more of land for minerals for the other.
