Bongata ba mefuta ena e kanna ea fumaneha merung ea tropike hape, ha ho makatse hobane ke moo mefuta e mengata ea liphoofolo tse anyesang e fumanehang teng. Empa ho ka etsahala hore ebe mefuta e sa tsejoeng e lula sebakeng seo batho ba lulang ho sona joaloka United States. Lab ea Carstens e khethile tse ling tsa tsona.
