Mankind must abandon earth or face extinction: Hawking
LONDON — Mankind's only chance of long-term survival lies in colonising space, as humans drain Earth of resources and face a terrifying array of new threats, warned British scientist Stephen Hawking on Monday.
"The human race shouldn't have all its eggs in one basket, or on one planet," the renowned astrophysicist told the website Big Think, a forum which airs ideas on many subjects from experts.
"Our only chance of long-term survival is not to remain inward looking on planet Earth, but to spread out into space," he added.
He warned that the human race was likely to face an increased number of events that threaten its very existence, as the Cuban missile crisis did in 1962.
The Cold War showdown saw the United States and Soviet Union in a confrontation over Soviet missiles deployed in Cuba, near US shores, and brought the world to the brink of nuclear war.
"We are entering an increasingly dangerous period of our history," said Hawking.
"Our population and our use of the finite resources of planet Earth are growing exponentially, along with our technical ability to change the environment for good or ill."
If we want to survive beyond the next century, "our future is in space," added the scientist.
"That is why I'm in favour of manned, or should I say 'personed', space flight."
His comments came after he warned in a recent television series that mankind should avoid contact with aliens at all costs, as the consequences could be devastating.

Pak floods, Russia wildfires and China landslides due to global warming: Experts
Wed, Aug 11 12:50 PM
London, Aug 11 (ANI): Climate change experts are of the view that global warming predictions are correct and the world weather crisis that is causing floods in Pakistan, wildfires in Russia and landslides in China is evidence that.
The torrential rains have affected almost 14 million people in Pakistan, making it a more serious humanitarian disaster than the South Asian tsunami and recent earthquakes in Jammu and Kashmir and Haiti combined.
The disaster was driven by a 'supercharged jet stream' that has also caused floods in China and a prolonged heat wave in Russia, The Telegraph reports.
Experts from the United Nations (UN) and universities around the world said the recent "extreme weather events" prove global warming is already happening.
Jean-Pascal van Ypersele, vice-president of the body set up by the UN to monitor global warming, the Intergovernmental Panel on Climate Change (IPCC), said the 'dramatic' weather patterns are consistent with changes in the climate caused by mankind.
"These are events which reproduce and intensify in a climate disturbed by greenhouse gas pollution. Extreme events are one of the ways in which climatic changes become dramatically visible," he said.
The UN has rated the floods in Pakistan as the greatest humanitarian crisis in recent history, with 13.8 million people affected and 1,600 dead.
Flooding in China has killed more than 1,100 people this year and caused tens of billions of dollars in damage across 28 provinces and regions.
In Russia the morgues are overflowing in Moscow and wildfires are raging in the countryside after the worst heat wave in 130 years, The Telegraph reports.
Dr Peter Stott, head of climate monitoring and attribution at the Met Office, said it was impossible to attribute any one of these particular weather events to global warming alone.
But he said there is "clear evidence" of an increase in the frequency of extreme weather events because of climate change. (ANI)
