Environmental lawyer Robert F. Kennedy Jr. makes remarks during a rally Monday, May 7, 2012, in Portland, Ore. Columbia Riverkeeper, the Sierra Club, Climate Solutions and Greenpeace sponsored the rally to fight a half-dozen proposals to ship coal from Montana and Wyoming to Asia through Northwest ports. The opponents warn of local problems from coal dust and long coal trains. They also say expanding Asian access to American coal would be bad for the world environment.  (AP Photo/Rick Bowmer) less
