An activist hangs from the St. Johns Bridge in Portland, Ore., Wednesday, July 29, 2015, to protest the departure of Royal Dutch Shell PLC icebreaker Fennica, which is in Portland for repairs. The icebreaker is a vital part of Shell's exploration and spill-response plan off Alaska's northwest coast. Greenpeace officials say the activists have enough water and food to last for days, and can hoist themselves to allow other marine traffic to pass. (AP Photo/Don Ryan), APTOPIX
