The world will end and will end very soon.
With everything like nuclear weapons, the nuclear bomb that destroyed that destroyed that asian city place, it exploded several kilometres away from the city. That's nothing to the nukes of today, if there were a nuclear war it would pretty much destroy everything, since bombs are extremely more powerful now, and everyone has em now.
And also don't forget global warming, the world is warming up too fast, in about 5 years there will be NO permanent ice left up in the north pole. And also animals cannot adapt to this enhanced greenhouse effect, forests can only march north so much a year, but the planet is warming up too fast for them, so the forests will die out cause they can't relocate fast enough. Also this will also stop the convection stuff in the ocean which cause's the ocean currents which brings the upwelling of nutrients which allows the little microscopic plants on the oceans surface to live(they produce most of the oxygen in the world, and clean out CO2), so the amount of CO2(greenhouse gas's) will increase, and there also won't be enough oxygen in the world and everyone will die out. Also there are many other effects of the global warming which is very destructive, for example australia is experiencing a "drought" because of global warming, and in the subarctic, where reindeer eat by digging through the snow to get to lichens and stuff on the ground, they can't cause the snow melts then freeze's again into ice, so they starve and the people up there can't eat cause the reindeer die out. We HAVE TO STOP before nature goes into a loop thing where the trillions of tons of methane and CO2 and stuff locked in the tundra is released from the ice's cause of global warming, and then cause's even further global warming which melts more, cause once that happens then there is nothing we can do to stop it!
