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 destoryed without
mercy so that dust stroms come into being affecting distant cities.
Last year, secientists saw some monkeys rubbing themselves with a certain kind of
insects to protect themselves form 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 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 pease can we smile
in relief.
