I haven't got a clue, I just don't think it will happen in my lifetime.
So, How will the world end, and when?
My money is on an asteroid strike.
Sometime BEFORE the sun becomes a red giant and incinerates the inner planets.
Not a clue. But I hope I’m asleep and know nothing about it.
Don't know. Don't care. That is not to say I don't care about taking care of our planet, because I do.
