To ensure survival, humans should leave earth within next 100 years

Renowned English theoretical physicist Stephen Hawking says that humans have to find and colonise in another planet within the next 100 years to survive climate change, asteroid strikes and overpopulation in our earth.
In a documentary, Expedition New Earth – part of the BBC’s new science season Tomorrow’s World – Hawking and his former student Christophe Galfard will travel the world to find out how humans could survive in outer space.
In the series, Hawking claims that time is running out for the Earth and humanity will need to leave the planet for its survival.
Hawking believes that our species would go extinct sometime within the next hundred years if we fail to find a new Earth, which lends the TV series its name. For the new show, Hawking has worked alongside Prof Danielle George, who teaches radio frequency engineering at the University of Manchester, and Christophe Galfard, a student of Hawking’s, to explore the idea of travelling across the stars.
Last month, Prof. Hawking had warned that the aggressive instincts of humans, coupled with the fast pace of growth in technology may destroy us all by nuclear or biological war, adding that only a ‘world government’ may prevent this impending doom.
Prof. Hawking had said that humans may lack the skills as a species to stay alive.
