What I wrote at the Wall Street Journal about birds: "200 million years of evolution but only 500 years to wipe out 190 species thanks to humans."

"Birds are not only the proverbial canaries in the coal mine that by their presence and health tell us if something is wrong with our environment. They are subjects of admiration in their own right. It took evolution only several million years to produce us from a furry ape, but it has been working for perhaps 200 million years to make present-day birds out of dinosaurs."
200 million years of evolution but only 500 years to wipe out 190 species thanks to humans.
From wikipedia "Since 1500, over 190 species of birds have become extinct, and this rate of extinction seems to be increasing."
"Currently there are approximately 10,000 species of birds, with an estimated 1,200 considered to be under threat of extinction."
Google "List of extinct birds".
