Dinosaurs died out because of an unexpected incident. But wildlife today disappears or is in danger just because humans do harm to it. For example, tigers are hunted for fur to make carpets so that they can only live in secure reserves; Grassland is destroyed without mercy so that dust stroms come into being affecting distand cities.

last year, scientists saw some monkeys rubbing themselves with a certain kind of insects to protect themselves from fierce mosquitoes biting. According to the result of the inspection, they found that the insect contains a powerful drug. So local farmers were employed to catch the insects. The ending was that the insects disappeared from the whole zone. When told that it was a loss to humans, the farmers burst into laughter and responded, " Our real loss is our decreasing income."

We should appreciate the natural balance and pay more attention to the importance of wildlife protection. Not until we succeed in letting wildlife live in peace,can we smile in relief.
