Caked in mud up to their knees, a small group of Indonesian youngsters plant mangrove saplings along a stretch of exposed coastline next to the Java Sea under the watchful eye of local environmentalist Samsudin.

A former school teacher, Samsudin has now dedicated his life to conservation and uses puppetry and storytelling to spread his message to the young about the importance of protecting mangroves in an area suffering massive coastal erosion.

"To keep tides from hitting us, we plant mangroves, forests for animals and oxygen for us to live. I weave everything into my stories," said Samsudin, 50, as he mused how some people in the area saw mangroves as a "nuisance" and would pull them out.
