Pemba students planting mangroves

Students in Wesha, Pemba planting mangroves to restore a local ecosystem damaged by an oil spill. Mangroves help stabilize the fragile coastline and provide habitat for numerous species of fish, crustations, birds and insects.
Coastal regions like this one in Pemba are being affected by rising sea levels, threatening peoples and their land. Many of the participating schools are near coastal areas. What are the difficulties for communities living near these areas? What are the possible solutions that could help to solve these problems?
