President Obama is celebrating Earth Day by flying in his jumbo jet down to Florida so he can tour the Everglades. The 1,836-mile roundtrip will consume 9,180 gallons of fuel on Air Force One, according to CBS White House reporter Mark Knoller. And that’s just the president’s plane. There will a half-dozen support planes along for the trip, Marine One helicopters, and a 25- to 30-vehicle motorcade belching exhaust into the air.
