Cities are where most people live and most economic activity takes place.
I was raised in a small town called Hornsea on England’s east coast, a magnificent placethat attracts tourists but is eroding faster than the rest of Europe. Some of the impressive, clay cliffs are literally crumbling. Local roads and the old settlement and have fallen into the sea. More than once, forward-planning residents have demolished and rebuilt their houses from salvaged materials as their coast recedes.
