Loggerhead sea turtle the connection between rapid global temperature changes and the possibility of population extinction. A more localized effect on gender skewing comes from the construction of tall buildings, which reduce sun exposure, lowering the average sand temperature, which results in a shift in gender ratios to favor the emergence of male turtles. Since the loggerhead occupies such a broad range, successful conservation requires efforts from multiple countries. Loggerhead sea turtles are classified as vulnerable by the International Union for the Conservation of Nature and are listed under Appendix I of the Convention on International Trade in Endangered Species, making international trade
