Which agency's role includes regulating the trade of turtles under CITES?

The correct choice is linked to the specific role that the US Fish and Wildlife Service (USFWS) plays in the regulation and conservation of wildlife, including turtles, under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). The USFWS is the designated authority in the United States responsible for implementing CITES, which aims to ensure that international trade does not threaten the survival of species. This includes issuing permits for the import and export of turtle species listed under CITES and monitoring their populations to ensure sustainable trade practices.

The other agencies mentioned have different focuses that do not directly involve the regulation of wildlife trade under CITES. The National Oceanic and Atmospheric Administration (NOAA) focuses on ocean and atmospheric sciences but does not handle wildlife trade. The Environmental Protection Agency (EPA) primarily addresses environmental pollution and regulations related to human health and environmental protection, and the Department of the Interior oversees various federal land management agencies but does not specifically handle the wildlife trade regulations established by CITES. This specialization of the USFWS in wildlife trade and conservation under CITES positions it as the correct answer to the question.
