Oregonians rally in Portland’s Pioneer Square Monday, May 7, 2012, to show their opposition to shipping dirty coal on trains and barges through Portland and other Northwest communities for export to Asia. Currently, six proposals would export a stunning 146 million tons of coal every year. This would require over 50 coal trains per day, every day, including 12 trains (6 full, 6 empty) per day through North Portland. Photo by Steve Dipaola//Greenpeace
