Cameroonian Fishermen Harvest Invasive Aquatic Fern to Create Energy Source

Cameroon's largest lake, Lake Ossa, has been invaded by salvinia molesta, an aquatic fern native to Brazil that hinders navigation, makes fishing impossible and blocks water access. Now, to combat the spreading plant, a local aid group is training fishermen to harvest the fern and transform it into organic coal. Anne Nzouankeu reports from Dizangué, Cameroon.
