All of this talk about trees reminds me of one of my favorite Dave Barry
quotes:
"Wood has been the preferred building material for thousands of years,
because it is one of the few materials that will rot as well as burn." -
Dave Barry
But that's just the way I am...

Folks, the last tree got struck by lighting, and burned to the ground.

In which you will read (if you read far enough):
Possible solutions to the 'tragedy'
The tragedy of the commons can be seen as a collective prisoner's
dilemma. Individuals within a group have two options: cooperate with the
group or defect from the group. Cooperation happens when individuals
agree to protect a common resource to avoid the tragedy. By cooperating,
every individual agrees not to seek more than his share. Defection
happens when an individual decides to use more than his share of a
public resource.
Game theory shows individuals benefit from defecting in the prisoner's
dilemma (even though both would be better off if both cooperated than if
both defected), unless there is some individual cost to defecting. In
the iterated prisoner's dilemma, retaliation for past defection can make
cooperation the best choice even for a selfish individual. Similarly,
far-sighted groups that impose some sort of sanction on members that
overexploit a resource can make over-exploitation unprofitable. This is
trickier for larger groups.
