Question 1
Why do people’s wants change over time? How does this affect production? Why can’t all wants be satisfied?
Wants change and producers respond, but scarce resources prevent satisfying every want.
Answer
Changing wants meet limited resources, so choices are necessary.
Question 2
How can continually changing wants put pressure on the environment? Can fulfilling wants and extracting resources be balanced?
More demand can increase extraction and waste; reuse, efficiency and cleaner energy help.
Answer
We can meet needs while using resources carefully.
