1. No..it is a natural cycle. The Sun has it's cycles too. Species evolve / die as the planet changes (always been like this)

2. No. They are hiding behind every tree. They have been ever since Oog believed something different from Erok.

3. Maybe. But that would depend on every nation willingly giving up their nuclear weapons programs. And I mean EVERY nation.
   pretty unrealistic, but a Maybe nontheless.

No,
 There is no chance, because no one will do anything about anything.

At least my children will know the fun of sitting in the alert hanger.

Sorry, humans are not that smart.

But....then again, maybe nothing will happen because no one cares.
