Demonstrators of the “No Tav” (No to High-Speed Trains) movement protest on March 3, 2012 in the center of Rome. The protest was organized by the No Tav movement and residents of the Susa Valley near Turin opposed to a planned high-speed train line in northern Italy. France and Italy signed a deal in 2001 on building a high-speed line through the Susa Valley area, a strategic link in the European network that would cut travel time between Milan and Paris from seven to four hours. The cost has been estimated at 15 billion euros (21 billion US dollars). But Susa Valley residents fiercely oppose the plan, saying the construction of tunnels would damage the environment.AFP PHOTO / GABRIEL BOUYS (Photo credit should read GABRIEL BOUYS/AFP/Getty Images)
