Sir Bob Geldof believes that the world will end in 2030 because of the effects of climate change.
The musician-turned-activist told a group of youngsters at a summit in Johannesburg, South Africa that the world can decide in a fit of madness to kill itself.
The 61-year-old singer also said that the next war is not going to be a World War One or a World War Two, it will be the end, the Daily Star reported.
He added that the humans may not get to 2030 and that the problem of climate change is need to be addressed urgently.
