Cigarette butts are seen in a public ashtray on the sidewalk of a street in Lisbon, Portugal, on Sept. 4, 2019. Portugal introduced on Wednesday a strict law aiming at combating smokers who throw the cigarette butts on the ground in public. The new law that approves measures for the collection and treatment of the tobacco waste enters into force on Wednesday. Whoever throws on the floor will be punished with fines between 25 and 250 euros (27.6 U.S. dollars to 276 U.S. dollars). (Photo by Pedro Fiuza/Xinhua)
