Dinosaurs died o because of an unexpected incident. But wildlife today d or is in danger just because humans do h to it. For example, tigers are hunted for fur to make carpets so that they can only live in secure r; grassland is destroyed without mercy so that dust storms come into b affecting distant cities.

    Last year, scientists saw some monkeys rubbing themselves with a c 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 l farmers were employed to catch the insects. The ending was that the insects disappeared from the whole zone. When told that it was a l to humans, the farmers burst into laughter and responded, "Our real loss is our decreasing income."

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