When artist Chapman Kelley was asked to create a public flower garden for a Chicago park, he designed it to be sustainable. Wild flowers were used - meaning no fertilizer or watering was needed, and when one variety had finished blooming, another would follow.

The Wildflower Works were started in 1984 and became one of Grant Park's most-loved features. But 20 years after Kelley invested a vast amount of time and money into the project, the city authorities took a lawnmower to it and chopped it in half.

He lost an initial case for infringement of copyright, but told Earth Beat host Marnie Chesterton why he’s not giving up the fight.
