Flooding already costs America $180 billion a year. By 2050, more than 300 million people will live with regular flooding.
Until now we’ve only had two options: build a seawall. Or give up and move.

How a “wood chip milkshake” can fix flooding
The forgotten 70s experiment that raised an island
How Terranova’s robots lift an entire city in place
A trillion-dollar gopher disaster waiting to happen
