Also the world was never a better place. There are always dangerous things. Don't be like those ignorant people that have plagued the generations before.
In my father's time there was the cold war and the Cuban missile crisis and people said the same thing about not wanting to bring kids into this world.
Also to answer your last question. I don't want to have kids, but not because of what you stated. I don't want kids because I don't want to take the time to raise any.
