Greenpeace activists display placards and mock container vans to represent 50 containers of waste that were shipped from Canada to the Philippines two years ago, during a protest near the Presidential Palace in Manila, Philippines Monday, May 4, 2015. Greenpeace urges President Benigno Aquino III, who is going to Canada on a state visit this week, to discuss the "illegal" waste issue when he meets Canadian Prime Minister Stephen Harper and Governor General David Johnson.
