     Every year more people recognize that it is wrong to kill wildlife for "sport." Progress in this direction

is slow because shooting is not a sport for watching, and only those few who take part realize the cruelty

and destruction.

     The number of gunners, however, grows rapidly. Children too young to develop proper judgments

through independent thought are led along way away by their gunning parents. They are subjected to

advertisements of gun producers who describe shooting as good for their health and guncarrying as a way

of putting redder blood in the veins (血管). They are persuaded by gunner magazines with stories honoring

the chase and the kill. In school they view motion pictures which are supposedly meant to teach them how

to deal with arms safely but which are actually designed to stimulate (刺激) a desire to own a gun. Wildlife

is disappearing because of shooting and because of the loss of wildland habitat (栖息地). Habitat loss will

continue with our increasing population, but can we slow the loss of wildlife caused by shooting? There

doesn't seem to be any chance if the serious condition of our birds is not improved.

     Wildlife belongs to everyone and not to the gunners alone. Although most people do not shoot, they seem

to forgive shooting for sport because they know little or nothing about it. The only answer, then, is to bring

the truth about sport shooting to the great majority of people.

     Now, it is time to realize that animals have the same right to life as we do and that there is nothing fair or

right about a person with a gun shooting the harmless and beautiful creatures. The gunners like to describe

what they do as character-building, but we know that to wound an animal and watch it go through the agony

of dying can make nobody happy. If, as they would have you believe, gun-carrying and killing improve human-

character, then perhaps we should encourage war.
