It’s rare, but it happens: There is some good news to share about the environment. Once endangered, sea turtle populations are on the road to recovery around the world thanks to local conservation efforts. Currently, six of the seven sea turtle species are listed as vulnerable, endangered or critically endangered on the International Union for Conservation of Nature’s Red List. (Critically endangered animals are just one step away from being extinct in the wild.) But new research published in Science Advances Wednesday found that the world’s populations of seven types of sea turtles are increasing across almost all of the 58 geographic regions studied.
