If a fox's favorite food is rabbit, it would benefit the fox to not indulge himself to the extent of eating all the rabbits in his neck of the woods.

The first political moderate ...

It would be wise to eat in moderation, to at least allow some rabbits to survive, so they can continue to reproduce.

Rabbits do reproduce very well ...and that is very well for a fox.

When I was growing up, there were those who liked to hunt without restraint ...but there were also Conservation Officers who roamed about, trying to encourage others to obey the rules, to conserve.  Most were friendly, and could just as accurately be called Conversation Officers, but whether they were called that or Rangers, ...they were appreciated by some, and disliked by others.

Within the hilly and much forested area of the Upper Peninsula of Michigan was a quite real threat of forest fires. There was a big tower on the top of one of the large hills overlooking my hometown.   From this tower, a fire could be spotted from miles around.

A story within a story ...

The first part of this part of the story, is about a report of rabid wild dogs roaming about the forest.  The Ranger warned the residents of the area not to allow their own dogs to be off a leash, to roam about.  Some of the residents did not believe there was a visible threat, and they resented being told what to do (even though it was only a recommendation).

That winter there was an unusually large snowfall.   The Ranger warned the residents along the river that their homes were in danger.  But it was also an unusually cold and long springtime ...allowing much of the snow to stay longer, and melt gradually.   Therefore, the riverbank was able to sustain the slow, steady thaw.
