Threats to sustainability arises due to scarce resources; if we used up scarce resources in the present day, future generations are unable to meet their needs.
What is Pareto efficiency? How is it illustrated on the PPC?
A firm / economy that is operating on the curve is Pareto efficient - one cannot be better off without making another worse off.
Why are there opportunity costs?
They arise due to the need to make choices as there are scarce resources.
