The problem isn't that Chicago is going to become uninhabitable. The problem is that food supply for billions of people are going to be threatened, that will make the flood of refugees from Syria seem like a trickle.

You can probably own a home if you want. You can travel the world if you want. You can meet a nice girl and cook food together in a cozy apartment. You can start brewing beer as a hobby with your friends. You can hike the Appalachian trail.
You can do a lot of things if you want.
