The most of bird species will disappear



Cagan H. Sekercioglu : scientist
There are about 10,000 bird species globally and most of them live on land. Based on the middle range of the Intergovernmental Panel on Climate Change’s projection of warming—3.5 degrees Celsius or 6.3 degrees Fahrenheit by the year 2100— 534 to 800 tropical land bird species could become extinct, out of a total of 7,565 species. Worldwide, of all of the 8,500 or so land bird species, as many as 600 to 900 could disappear. “Birds are sentinels of what’s happening to the planet, the canary in the coal mine,” he said. “If this is happening to birds, and they can migrate, then for other organisms, it’s going to be worse.”
