Nigerians strive to bring mangrove forests back to life

The team members plunge their shovels into the mud and slot in saplings at the site in Bundu, a shanty town on the outskirts of the southern oil city Port Harcourt. In recent years, human activity has destroyed swathes of the world's mangrove forests, which form a vital barrier against the tides and a sanctuary for wildlife. But in this part of the Delta -- plagued by leaks from multinational oil company pipelines and a host of other threats -- a local community leader is pushing ahead with a project to restore the spoiled forests.
