Final answer:
Scarcity necessitates that every choice has an opportunity cost, which is the benefit forfeited by choosing one alternative over another. This reflects the tradeoffs inherent in making decisions due to the finite nature of resources.
Step-by-step explanation:
Because of scarcity, every choice does indeed involve an opportunity cost. This is a fundamental concept in economics, where scarcity refers to the limited nature of society's resources. Opportunity cost is the benefit that you give up when you choose one alternative over another. Since resources are finite, every decision we make has a cost associated with it—this is known as the tradeoff.
In essence, when we make choices, we are constantly evaluating different possibilities and deciding which option provides the greatest benefit at the lowest cost. This does not always involve monetary transactions; it can also relate to the use of time, effort, or other resources that have value to us. The concept that every choice has a cost highlights the constant balancing act that occurs when we decide how to allocate our limited resources in the face of scarcity.
