That's how the world works.

How worried should I be? And how much should I doom prep?

If you have land it wouldn’t hurt to have some survival crops. Something like sunchokes (a.k.a. jerusalem artichokes, bad name because they’re not an artichoke and more like a sunflower) can grow well in a sectioned off space where they can’t spread. In an emergency the tubers can be dug up and cooked, though they’ll probably give you a lot of gas from the high incline.

Personally I love raspberries and black raspberries, which are easy to grow just don’t plant them where they can spread and run wild. It’s nice to have fresh berries!

I would go with parsnips as an alternate survival crop to sunchokes. I grow both but only use parsnip. They are aggressive re-seeders and produce huge roots.
You can find tons of parsnips growing wild along road in my area. Which makes foraging a very attractive option.
