City tries to block car pollution with wall of trees, bushes

LOUISVILLE, KY (WAVE) - Can trees and bushes block pollution from busy streets?

That's the question Louisville is trying to answer with a pilot project at St. Margaret Mary Catholic School on Shelbyville Road.

The "Green for Good" project will put a wall of plants in front of the school to try to filter out pollution from passing vehicles.

The school was chosen as the first location because it's on a busy road and had space for the buffer, but officials say scientists across the country will be watching to see if it works.

"So for the administration and the students at St Margaret Mary you guys should understand that you are national leaders in this kind of work," Mayor Greg Fischer said at a press conference on Wednesday.

The mayor says if the experiment is successful, it could be replicated throughout the city.
