Say, how about those termites?

[phantom power]

It looks like the entire continental United States will be inhabitable by termites, in a decade or so. Houses require periodic treatment with expensive chemicals to prevent being eaten. Pretty much all houses currently built are built with wood, and at the very least dry-wall and ferring strips. Termites are very happy to eat the paper backing on dry-wall. And, of course, the ferring strips holding it up.

So, imagine a future, say, thirty years from now, where (a) Every home in the continental US is vulnerable to termites and (b) nobody can afford the treatments to prevent them.
