Think Globally, Act ...?

At the Aspen Ideas Festival 2011.

Kai Ryssdal: Adriene Hill came into my office this morning and said, 'Hey, listen, I need you to quote Donald Rumsfeld when you set up my story on the show this afternoon.' And I said, 'OK, how come?' And she said, 'Because it really tees up where Americans are on the environment right now.'

So, loosely quoted, it goes like this: When it comes to our knowledge of and attitudes about the environment, there are known knowns, known unknowns, and unknown unknowns.

Here's Adriene.


Adriene Hill: First, the known knowns. When it comes to the environment, Americans pretty much think they've got it down.

Timonthy Kenyon: In 2011, seven in 10 said they new a lot or a fair amount about environmental issues and problems.

Timothy Kenyon is a researcher with GfK Roper. He headed up a consumer attitudes study (PDF) for SC Johnson, the cleaning products company. He looked at environmental attitudes over the last two decades and found a giant known unknown -- fewer people actually know what they can do to help the environment in big ways.

Not surprising, says Stanford professor Jon Krosnick.

Jon Krosnick: The change is that in recent years, climate change has become the focus.

And climate change is a big problem with no easy solutions. Talk of reducing future pollution now, well...

Krosnick: It's somewhat like saying to a cancer patient, now the bad news you've got cancer and it's a very, very serious problem. The good news is we can prevent you from getting more cancer.

But that known unknown hasn't stopped Americans from making small changes -- more people recycle now; more people buy green products; more people take public transit. Which leads directly to the unknown unknowns: Consumers often overestimate the effects of small actions.

And, says Oklahoma professor Riley Dunlap, there maybe too much focus on those types of changes in the first place.

Riley Dunlap: Many times, the solution to problems is not to ask individuals to change their behaviors, but to ask individuals to support legislation and policies.

Now you know.
