Renzo Piano sapling plan abandoned
Architect Renzo Piano says a project to plant 90,000 trees in the Italian city of Milan in honour of Claudio Abbado's return to La Scala has been abandoned.
Piano expressed his regrets at the project's failure in a page-one article published in daily newspaper Corriere della Sera.
Piano wrote that 100,000 trees offset the smog of 5,000 vehicles, lower urban temperatures and reduce humidity. They also "create a balance that is the secret of a happy city".
Abbado had requested 90,000 trees to be planted to mark his return in June to La Scala after 24 years.
Italian news reports say the city - after initially supporting the idea - says the project is too costly. City hall said it was preparing a response.
