| For：Doug Smith，Director of wolf recovery，Yellowstone National Park In the world today there is so much we are losing； more and more species disappear from the earth every year．The time has come to put something back，to restore（恢复）to treat some of the old wounds enforced on nature over the years． Wolves are animals killing and eating other animals in North America．They play an important role in keeping the continent healthy．Most places don't have enough wild country to make their restoration possible，which means it's even more important to restore wolves where conditions are right，places like Yellowstone，which has both a high level of wildness，as well as abundant creatures that wolves hunt and eat for living． Some who oppose wolf restoration have a human centered point of view that the earth is here for humans，we can use it whenever we want and for whatever purpose．But wolves offer us a chance to live another way-a way to learn to live with other life forms． | Against：Larry Bourret，Vice President，Wyoming Farm Bureau What does wolf introduction to Yellowstone mean？To the average citizen it probably just means introducing wolves to Yellowstone．There would be no unfavorable effects because few people live near Yellowstone． But to farmers it means introducing wolves，which wander over vast areas-in and out of the park-onto their farms．Wolves eat meat-as in the cattle，sheep that keep farmers in business．Introduction apparently also means lawsuits by environmental groups attempting to remove livestock（家畜，牲畜） from federal lands．To farmers，who own private lands in the same area，it means the possibility of ?nancial ruin．To farmers it is a form of land use restrictions．To farmers introducing wolves means taking away the farmers'livelihoods without just compensation．Why do people not want a nuclear power plant built in their backyard？For the same reason farmers do not want wolves introduced into their backyard． |
