Rock singer Bono has pledged to spend the rest of his life trying to help the impoverished around the world.
Bono addressed the Labour Party conference in September
The U2 frontman told BBC One's Friday Night with Jonathan Ross he wanted the current generation to be "remembered for something other than the internet".
It should be "the first generation to eradicate extreme poverty", he said.
"I want to spend the rest of my life doing that." His bandmates complained but supported his causes he said, adding it still felt great to be in U2.
Bono has been a high-profile campaigner on issues including third world debt and Aids, and has a close relationship with some of the world's most important politicians.
He said 1985's Live Aid concert, raising money for the starving in Africa, made him see what could be achieved.
Bono said world leaders looked at him like "sort of exotic plant"
"That day changed my life and started me on this incredible adventure," he said.
World leaders looked at him "like I'm some sort of exotic plant", he told Ross.
"But I've found them to be very respectful. When I met [Bill] Clinton, I looked like our road crew and he burst out laughing.
"I don't feel nervous, I feel they should be nervous because they're the ones who have to be held accountable."
U2 have just released their 11th studio album, How To Dismantle An Atomic Bomb, which has gone to number one around the world.
"We feel like we've just made our first album, we don't like looking back," he said. "It's a great feeling to be in this band at the moment."
Bono has been one of world's biggest rock stars since U2 rose to superstar status in the early 1980s.
