50 US cities may have to be bulldozed in order to survive

Pruning trees helps them. Parasitic insects cannot enter through dead limbs. There's enough space for new shoots to grow. And they don't break in the snow or the wind.

Pruning back overgrown cities seems very sensible to me. If you don't want to move, you get to live in the countryside!

So 'We had to destroy them in order to save them' has finally come home to America?

Who says there's no karma?
