The leatherback turtle is considered vulnerable to extinction globally, with some populations being critically endangered. All seven regions where leatherbacks are found face high environmental risks, according to a study co-authored by wildlife ecologist Bryan Wallace. Leatherbacks are known for their long migrations, with some swimming up to 3,700 miles each way, exposing them to unique risks throughout their journey.
On the other hand, green turtles are still considered endangered globally, but their populations show signs of recovery in many regions. Researchers found that by ending commercial harvests and allowing them time to rebound, green turtle populations are thriving in coastal waters off many regions of Mexico and the U.S. Co-author Michelle María Early Capistrán, a researcher at Stanford University, has conducted fieldwork in both countries and has observed the positive impact of conservation efforts on green turtle populations.
Overall, leatherback turtles are at risk of extinction, while green turtles are showing signs of recovery in some regions. Conservation efforts such as ending commercial harvests have helped green turtle populations rebound in coastal waters off Mexico and the U.S. More research and conservation efforts are needed to protect these marine species and ensure their survival in the face of environmental risks.
