Will we live forever on Earth?

Many scientists, including British physicist and cosmologist Stephen Hawking and the late American astronomer and astrophysicist Carl Sagan, have long been warning that it will be very difficult to avoid a disaster on Earth in the coming centuries or even years, so it is quite possible that the future of the human race must pass somewhere in the space.

Hawking thinks humanity ‘should not put all your eggs in one basket, or on the same planet’ and without hesitation supports serious research of life outside of our own, while Sagan argued that humans will eventually —doubtless— conquer elsewhere to live that we can not even imagine now, but also that those humans are very different from us. In this video he explains it in his own words.
