A federal agency said it would consider Endangered Species Act protections for ribbon seals, above, in the Bering Sea, and three other seal species that rely on sea ice for survival. The agency, the National Oceanic and Atmospheric Administration, accepted a petition from an environmental group, the Center for Biological Diversity, seeking threatened or endangered status for ribbon seals, above, because their habitat is melting from global warming brought on by humans. NOAA Fisheries also expanded the status review to include ringed, spotted and bearded seals.
