I mentioned the zombie outbreak as one of the possible things that could happen
It’s not. Zombies are fictional. There’s a zero percent chance of a zombie outbreak. And you are saying a major environmental change is just as likely.
but what about asteroid impacts? Why aren’t we building preventative measures against that?
…there is also scientific attention on this, and there are in fact preventative measures being planned.
To be fair, there’s a non-zero chance of a CJD outbreak, and same for wasting disease that originates from deer. If or when they cross over to humans, it’s going to be nasty.
