Gaze!

To teach a child admiration and respect for the wonders of creation, give him a magnifying glass. Have the child observe through the glass the beauty of the tiniest bug, and how one ant stops to greet another when passing in opposite direction. Let him examine caterpillars and toads. Show him the little moths powdered with silver or gold, which come to lighted windows at night; and butterflies with their elaborate patterns of color combinations.

A child who has gazed at the living wonders around him is filled with awe. He will not want to harm creatures who don't want to harm him.
