America's thirst for energy and high fuel prices after hurricanes Katrina and Rita have rekindled the fight over oil and gas drilling off Florida, where clean beaches are the bedrock of a $57 billion-a-year tourism industry. Environmentalists say they are girding for battle as pump prices of $3 a gallon soften longstanding support for bans on offshore drilling, once sacred to Florida politicians and the state's 17 million people. With Washington pressing for new domestic oil and gas sources to ease U.S. dependence on foreign energy, the eastern Gulf of Mexico, long sought by oil companies, has risen to the top of the national agenda again.
