Hawaii's Accidental Ecosystems

Hawaii's beautiful forests are a complete accident. On the island of O'ahu,

you're walking through a "freakosystem"—a wild landscape made of non-native species from all over the

world. Think Asian birds eating Brazilian fruit on a Pacific island.

These new ecosystems now run themselves, and some of Hawaii's last native plants actually depend

on these foreign birds to survive. Scientists see it as a crystal ball, offering a stark

glimpse into the future of nature.
