As sunshine starts to warm up the city, melting snow is revealing all kinds of litter, including massive amounts of cigarette butts discarded over the winter. For the first time, London's Environmental Network has signed the city up for a Butt Blitz, a national campaign to get as much of the disgusting litter off the street during the month of April. "For the month, we encourage people to pick up cigarette butts and at the end of the month to drop them off at a location and we'll send them off to get recycled," said the networks head, Skylar Franke.
