Dolphins need rest

Federal regulators are proposing to ban swimming with dolphins in Hawaii, a move that could imperil one of the state’s most popular tourist activities and the industry that has sprung up around it. The National Marine Fisheries Service says spinner dolphins – the playful nocturnal species that humans in Hawaii routinely frolic with – are being deprived of rest during the day and becoming stressed out. Dozens of companies on Kauai, Oahu, Maui and the Big Island operate dolphin tours daily.
