You know, how do you see this decision by the Trump administration to roll back these standards? How is this significant for air pollution, for climate change?

That's a great question.

And I think what's so striking about it is that it's the 21st century.

We know how to reduce air pollution from cars by improving vehicle efficiency or switching to electric vehicles with no tailpipe pollution.

We know that we can make it easier for people to bike and walk and use transit.

And in recent years, a lot of policies have been put in place to help us reduce this pollution that are now being rolled back.

And there's a few ways this rollback will impact us here.

So what's the status of that?
