A big wild stag was wandering over the hills and through the valleys somewhere in southern Finland. By chance he found a pile of old potatoes which were brought there by a farmer living in the neighborhood.
"Delicious", the stag thought, "it must be refreshing for a change to eat potatoes instead of pine and birch saplings."
But what might the forest owner think of the big wild stag?
He thinks the big wild stag can't cope for long by eating potatoes. When all the potatoes are eaten, the big wild stag begins to use again pine and birch saplings to nourish himself.
Many are of the opinion that the big wild stag is the worst pest in Finnish forests.
Perhaps, however, it's is an exaggeration to say so. The big wild stag is useful for instance because it is a game animal. It can be hunted and its meat can be eaten. It also brings indirect economical benefits because the hunters need to buy guns, accessories and services for hunting.
And from an ethical point of view to make use of nature is the general condition of life. In this respect the big wild stag acts exactly likewise a human being.
