As Houston begins recovery efforts from Hurricane Harvey, a new storm threat.

Hurricane Irma is barreling west towards the Caribbean in Florida.

We have few defenses against hurricanes lashing rains and wind and storm surge.

But nature does provide one.

Wetlands act in two ways to reduce the impacts of storms.

They reduce storm surge by acting as a wall or a barrier,

and they act as a sponge by soaping up the waters that come down via rainfall.

Michael Beck is a coastal scientist at the

Nature Conservancy and the University of California Santa Cruz. He says as we've paved over swampy

coastlines, we've changed how storm waters flow. Or, for an analogy, a little closer to home,

rain falls on your driveway, it's going to run straight out into the street. Rain falls in your garden, it's going to soak into the ground.

And so when you've done that at the scale of whole watersheds, there's no place for the water

to go when it rains.

But some wetlands do remain.

Back in his colleagues teamed up with the insurance industry, and using the industry's

risk assessment models asked, how much more damage would Hurricane Sandy have delivered if
