On March 2, the federal Fish and Wildlife Service removed the Eastern Cougar from the endangered species list to the extinct species list. Since 1973, the Eastern Cougar has been on the endangered species list. According to the record, the last time humans saw the Eastern Cougar is in Maine was in 1938. The Eastern Cougar’s habitat stretches from eastern Ontario and Michigan eastward to Maine and southward to Georgia, Tennessee and Missouri. However, they are such a ferocious animal which will threaten many domestic animals, so they are human’s hunting target. During the past 5 years, scientists cannot find any evidence which can show that the Cougar is in active, and the amount of their prey, deer, has largely increased. So many of the evidences have shown that the Eastern Cougar is extinct. In addition, one of the Eastern Cougar’s relative, Florida Panther, is also in danger too. there are only less than 100 of them left in the States, so the Fish and Wildlife Service has put this species under protection under the Endangered Species Act.
