"Since 1900, 543 species of vertebrates have gone extinct. And those are just the ones we know of. In the past century, we have witnessed the disappearance of the ivory-billed woodpecker (Campephilus principalis), the Round Island burrowing boa (Bolyeria multocarinata), the laughing owl (Ninox albifacies), the sea mink (Neovison macrodon), and the golden toad (Incilius periglenes), to name a few."
