Rome highlights the environment with annual Earth Day.

Rome marks the international Earth Day initiative on 22 April with five days of events on the theme of the environment and sustainability at the Galoppatoio area of Villa Borghese.

Running from 21-25 April, the programme of free events features exhibitions, workshops, concerts, sporting and children’s activities.

Earth Day was founded by US senator Gaylord Nelson in 1970 and is celebrated in more than 190 countries worldwide on 22 April each year.

The event is designed to raise awareness about our natural environment and how to conserve it.
