The Voice judge had been meeting climate change experts at Oxford University as part of a guest speaking role. Despite his environmentally-conscious stance on green issues, the Black Eyed Peas rapper, 37, chose to take a private helicopter to the venue. It is understood the journey, which is a 286 mile round-trip from London, used 71.5 gallons of fuel and released three-quarters of a ton of CO2 into the atmosphere. He even tweeted pictures of the so-called “hip.hop.copter” for fans to admire, after landing at the Oxford's University Parks. From there, the singer used a pedal cycle to travel the remaining few hundred yards to the Radcliffe Observatory Weather Centre. There, he told an audience: “Climate change should be the thing that we are all worried and concerned about as humans on this planet, how we affect the planet, our consumption, and how we treat the place that we live in.” According to the Daily Star newspaper, he spent an hour meeting with climate expert Myles Allen, before travelling to Taunton, Somerset, to carry the Olympic torch. Professor Allen told the newspaper: “The irony didn’t escape everybody. But he’s committed to the issues and he’s written songs about it.” “A better understanding of the problems is probably more important than whether Will flies a helicopter from London to Oxford.” Psssss…..sure professor whatever you say. Heheh he rode on a bike for the last hundred yards…like uhhhh gee see how much energy I saved? What a hyprocrite!!
