It's said that 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 only live in secure reserves; grassland is destroyed without mercy so that dust storms come into being affecting distant 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 tears 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.
据说恐龙因一次意外事件而灭绝了，但是今天的野生动植物却是因为人类的伤害而消失或处在危险中。例如，老虎被猎杀以获取皮毛做地毯，结果它们只生活在安全的保护区里；草地被无情地破坏，以至于沙尘暴开始形成影响遥远的城市。
去年，科学家观察到猴子在身上擦某种昆虫来保护自己不受凶猛的蚊子的叮咬。根据检查的结果，他们发现这种昆虫含有一种具有强大效力的药物，于是，当地的农民都被雇用捕捉这种虫子。结局是，这种昆虫从这整个地区都消失了。当被告知这是整个人类的损失时，农民们都突然哭着回应道：“我们减少收入才是我们真正的损失呢！”
我们应该意识到自然平衡并多加注意保护野生动植物的重要性。直到我们成功让野生动植物平静地生活，我们自己才能如释重负地笑开颜。
