Mexico - Climate - Loggerhead Turtle
A loggerhead sea turtle in Akumal Bay in Yucatan. Endangered sea turtles have been protected in Mexico since 1990, and both the government and private volunteers have done great work preserving their habitat and helping the turtles.
Now the turtles are in trouble again, and protected habitats can do little to help them. Global warming cause sea level rise, which erode the beaches where the turtles lay their eggs. Warmer weather also affect the gender of the turtle hatchlings. Turtles are reptiles, and the gender is determined by the temperature in the nest. The cooler area of a nest will typically produce more males, while the warmer part will become females. On the Pacific coast of Costa Rica, nests are now producing between 70 and 90 percent female hatchlings. Coral reefs are a vital food source for sea turtles, and the Caribbean region has lost fifty percent of its corals since 2005 largely due to warmer oceans.
