Grim forecast
How many bird species are in trouble? BirdLife International says no fewer than 1,331. Brazil alone has over 100, mainly because of deforestation. Contrarians sometimes point out that most of the area marked deforested is not turned to concrete, but replanted with a crop or a cultured tree species, but the disruption even in these cases is huge, and birds don't take well to that. Ask the ivory-billed woodpecker, if you can find one: there were plenty of forested habitats remaining, but it apparently couldn't adapt well from old growth to secondary growth, and I think we lost it for good.
