問題詳情

(46~50) If you know the food chain, you will not feel surprised that all living things live on each other for food.Zebras, for example, eat grass, but then they may be eaten by lions or other predators. Then people kill someof these predators for their meat. So, at the top of the food chain is man, who eats many of the plants andanimals on earth. Now we may have an idea that we can get these plants and animals for food as we like. However, thefood chain may get broken because of our overfishing or hunting. If this does happen, many other animalsmay die. Think of the following example. If we kill too many fish, jellyfish or shrimp, dolphins may havedifficulties getting enough food. Then there may be fewer dolphins in the sea until some day children no longer have any chance to feed,touch or hug a dolphin at the ocean park. Now you see we humans decide not only our own future but alsothe existence of other living things. *chain 鏈; predator 掠奪者; jellyfish 水母; shrimp 蝦; no longer 不再; exsitence 存在; human 人類
