I think mankind can be extinct when a huge natural disaster occurs. Long time ago, the dinosaursruled the world but they all diedbecause of a meteorite which crashed down to earth. The same thingcould happen to us too. I know humans arereally good at Science, and maybe we could survive the thing thatthe dinosaurs didn't. But we can't do anything ifsomething as big as Jupiter or sun crashesinto earth. Let's say that we survived the Jupiter-sized meteorite that crashed down toearth. But when we go up there is no food or water. Nobody will survive except for super heroes.But if someone will ask me, 'Can't you invent food orwater?' I will say yes. Then the one who asked me will tell methat I can survive with inventingfood. I will tell him that I can only invent a littleamount of food and nobody can live longer. So this isthe reason why I support my idea, and also this is myhomework. See you later!
