About 50 years ago, there were few wolves left in the United States. Many had been killed because they were seen as pests or competition for food animals such as elk or deer. The Endangered Species Act was passed in 1973 to help protect animals and plants in danger of becoming extinct. Without it, there might be no wild wolves today in the United States.
