00:00imagine waking up to a world where five billion people are gone in just days sounds like science fiction but
00:06scientists say it could happen if nuclear war breaks out after recent tensions in the middle east experts are warning
00:12about the worst case scenario a global nuclear war would not just destroy cities it could change the entire planet
00:19according to author annie jacobson the first seventy two minutes of a nuclear exchange could kill billions but the real
00:25nightmare comes after massive firestorms would send smoke into the sky
00:30the sun would be blocked temperatures would crash and earth could enter a mini ice age lasting around ten years
00:36crops would fail across most of the world with no food billions more would die from starvation radiation would also
00:43damage the ozone layer
00:45that means sunlight itself could become dangerous many survivors might be forced to live underground just to stay alive but
00:52surprisingly experts say two countries might still survive better than the rest
00:56australia and new zealand because of their location and climate scientists believe these countries could still grow food even during
01:04nuclear winter that could make them among the only places able to sustain agriculture
01:09other countries sometimes considered relatively safer include iceland switzerland chile south africa and tuvalu but survival would still be incredibly
01:19difficult
01:19the truth is in a nuclear war no place on earth would truly be safe and that's why preventing it
01:26may be the most important mission humanity has
