Listed is an inventory of U.S. vertebrate species—mammals, birds, reptiles, amphibians, and fishes—listed as threatened or endangered under the Endangered Species Act of 1973. Most of us will never encounter these species in the wild. Many are small and unassuming in appearance. Others inhabit remote wilderness or the vast oceans. But each one has unique intrinsic value—from the tiniest minnow to the noblest predator. Becoming acquainted with nuances of behavior or habit of seemingly insignificant species can build an umbilical to the earth we all share.
Listed serves as a reminder of how many species, in our country alone, will either continue to exist or disappear forever depending on choices we make both as individuals and as a nation. We should keep them here with us. Just because we can.
