Well... there is a great chance humans can destroy this planet, some believe Climate Change could do us in, others think Nuclear Weapons. Regardless, whatever happens, the planet will likely rebound, we might be gone, but the planet will survive. But if us and our planet is gone it will be difficult to destroy other planets, I don't see that happening.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
