Obviously the issues are timely. In the interest of a discussion--let us look at the various "commons" that have been exploited to the point of collapse.

The ecosystem for certain, 

Of course the atmosphere in general. . .but also.

The economy, where it is in everyone's interest develop new buisiness, hence oversaturating every market. . .

In relationships between people, where the "common" responsibility and good will is often taken for granted and exploited.

In one's personal health,

Indeed in one's mental health. . .

Perhaps the greatest ethic we can hold up at this moment in history is "restraint?"
