A considerable amount of consumer plastics, metals, rubber, paper, textiles and fishing gear are discarded into the marine environment every day, making marine debris one of the most extensive pollution problems our planet is facing today. These materials can be considered as a possible vector for the introduction of non-indigenous species as some species are capable of surviving long and stressful journeys in the open ocean. Our group will also try to establish a cooperation with the local nautical recreational sector so they can contact us when they find relevant marine debris in Madeiran waters.
