It took Rodolfo Galuna only 15 days to build the small wooden boat he named "Rona". But now the 52-year-old fisherman has no use for it. Black, stinking oil sludge covers the boat’s hull, has crept into Galuna's back yard and quietly destroyed this fisherman's livelihood here on Guimaras Island. "I don't know what we will be living off in the future", said the father of six, "I must find something new". It is day ten of the biggest oil spill in the history of the Philippines.
