Naturalist and professional diver Sandra Bessudo has worked for decades to conserve marine life around Malpelo Island, off the coast of Colombia. The island, a Mission Blue Hope Spot, is home to important ecosystems that support the wider health of the South Pacific Ocean. Together with neighbouring Hope Spot Champions, Bessudo works to create additional “swimways” between Malpelo and other regional protected areas that help increase the populations of migrating species such as hammerhead and silky sharks
