The 30 activists from the Greenpeace ship Arctic Sunrise being held by Russia hail from 18 different countries with diverse backgrounds and ages. Dubbed the \"Arctic 30\" by the environmental group, those detained range from the veteran captain of the Greenpeace ship Rainbow Warrior bombed in 1985 in New Zealand by French agents, to the great-grandson of a Soviet foreign minister.
