EARTH is a doomed planet and if humans do not act fast, humanity faces going down with the ship, Professor Stephen Hawking warned in his last book.
Hawking predicted that the earth would turn into a giant ball of fire by 2600 and humans would need to colonize another planet or face extinction. However, many possible scenarios of anthropogenic extinction have been proposed; such as human global nuclear annihilation, biological warfare or the release of a pandemic-causing agent, overpopulation, ecological collapse, and climate change.
