Tragedy of the Commons:A situation in which individuals, acting independently and rationally according to their own self-interest, will ultimately deplete or destroy a shared resource, even when it is not in anyone's long-term interest for this to happen.
Renewable and Non-renewable Resources: Renewable resources are natural resources that can be replenished or regenerated, such as solar energy, wind, and forests. Non-renewable resources are finite resources that cannot be replaced once they are depleted, such as fossil fuels and certain minerals.
