People in a rural community share a forest. By agreement, each family can cut 10 trees per year for personal use. One year, one person cuts 20 trees to build a shop that's nicer than the neighbor's shop. The

new shop flourishes, and despite the general disapproval, nothing is done to punish the cheater. The

neighbor, seeing this, decides that it's okay to go ahead and take 25 trees. Other neighbors follow suit. After

a few years, the forest plot is gone, and everybody must travel much farther for wood. What's this an

example of?

O A Natural Law of the Land

OB. Tragedy of the Commons

OC. Voluntary approach to environmental policy

O D. Conservation Property RightS
