Touring a Thai gypsy village damaged by the 2004 tsunami, former U.S. President Bill Clinton on Saturday expressed concern that most of the survivors left homeless by the massive waves are still living in temporary shelters. «Only 30 to 35 percent of the people have been put back into permanent housing,» Clinton said of the nearly half-million homeless survivors in a dozen countries. «We have to do better than that.» Clinton, on his final trip to the region as the top U.N. envoy for the tsunami recovery effort, also uses his visit to promote a World Conservation Union program to rebuild Thailand's Andaman Sea Coast, where the massive waves killed more than 5,400 people. Noting that coastal deforestation significantly worsened the destruction from Hurricane Katrina, Clinton praised the villagers in Hin Look Dio for attempting to preserve their natural habitat. Known as the Moken, the gypsies are seafaring people who live in Thailand and Myanmar. «This little tree is symbolic of a balanced life and how they (the Moken) help each other preserve their villages,» he said as he planted a mangrove sapling. Nearly a quarter-million people in 12 Indian Ocean countries died in the Dec. 26, 2004, tsunami caused by a massive, magnitude 9.3 earthquake off Indonesia's Sumatra island. U.N. Secretary-General Kofi Annan appointed Clinton to be a special envoy for tsunami relief for a two-year period ending Dec. 31. Clinton flew from Thailand to the Indonesia's Aceh province, which was hit hardest by the tsunami, the Associated Press reported. He will visit a military-style barracks built by the government to house some of the nearly 500,000 tsunami survivors, as well as a temporary housing site built by the Australian Red Cross. He will also visit a school and present land titles to several new homeowners.
