This article is about the release of a study that has found that 1/3 of the U.S.'s 800 species of birds are now endangered. Problems like pollution and habitat destruction have been sited as some causes. On a more positive note, it has been found that species relying on wetlands are bouncing back as wetland conservation increases. This means that if people take action there is hope to reverse these ill-effects before it gets too far.
