One Tunisian preserves rubbish from local beaches to raise awareness about the environment and the plight of refugees. "In his own words, Mohsen Lihidheb is “a nobody and everybody at the same time”. The former post office worker from Zarzis, Tunisia, used to lead an ordinary life, until he was inspired to do something more meaningful. Having grown up by the sea, Mohsen has been collecting objects he found on the beaches of Zarzis for 23 years – items like bottles, buoys and dolphin bones. He puts them on display at this own small museum or turns them into art installations."
