Recently, news has often come that animals in the zoos attack tourists. That results from the fact that tourist though rarely reported, often annoy or hurt the animal.

Just as we can see in the picture, a child is to throw a stone at the elephant, and the elephant holds a board, reading “I’ll take revenge on the person who inures me.” Similar happenings often occur in our daily life. Neglecting the rules in the zoo, many tourists throw such things as food, garbage, or even stone at the animals, causing injures to the animals. Consequently some of the animals attack the tourists in return.

We all know that one good turn deserves another. Vice versa, one bad burn deserves another, too. Animals are our friends. Being kind to animals is being kind to ourselves.
