Mangrove forests are among the most threatened habitats on earth, disappearing faster than even rainforests. But mangroves are also the coast’s nursery, providing shelter for 75% of commercially caught fish. Kenya has lost a fifth of its coastal forests in 25 years. Laws now protect this critical plant, the one one capable of growing on the edge of salt water. But some locals complain, that Kenya’s strict ban against mangrove harvesting has left them them destitute.
