Rome highlights the environment with annual Giornata della Terra.

Rome marks the 48th edition of 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. 
The day is also being marked at the Auditorium Parco della Musica as part of Rome's 13th annual Science Festival, produced in partnership with the National Geographic for the second consecutive year, together with the Italian Space Agency and the National Institute of Nuclear Physics.
The 2018 theme is dedicated to battling plastic pollution, highlighted at Rome's Science Festival with a 10m-long whale constructed of 250kg of plastic waste - the equivalent amount of plastic dumped into the world's oceans every second of every day. "Plasticus the Whale" is part of the Sky Ocean Rescue initiative and can be visited each day of the science festival, which runs until 22 April.
Founded by US senator Gaylord Nelson in 1970, Earth Day is designed to raise awareness about our natural environment and how to conserve it. This year it will be celebrated in 193 countries worldwide.
