Some time ago, I found in my letterbox a little magazine from the World Wide Fund for Nature. It had two photos side by side. One was of a young gorilla. "This is a species（物种）of mammal （哺乳类动物）," said the words below it. "It is being destroyed by man. We must save it for our own good." The other photo showed a human baby. The words also read, "This is a species of mammal," but then went on: "It is the most destructive（破坏性的） on earth. We must retrain（教育）it for its own good."
