Final answer:
Garrett Hardin's proposed solutions to the tragedy of the commons include government regulation, privatization, and population control, but not explicitly moral suasion.
Step-by-step explanation:
Garrett Hardin suggested several potential solutions to address the tragedy of the commons, where individuals acting in self-interest can lead to the depletion of a shared resource. The possible solutions proposed by Hardin include government regulation, which would entail the government taking control to protect the commons by force or through other authoritative means. Another solution is privatization, where the commons would no longer be open to all, but instead individuals or entities would possess and manage the resources. Hardin also considered population control as a means to reduce the pressure on resources. However, moral suasion, which involves influencing or persuading people to act in the public interest without force, is not explicitly mentioned as one of Hardin's solutions.
