Greenpeace activists stand in solidarity with the crew of the Greenpeace ship Arctic Sunrise.

Tens of thousands of people participate in activities held in over 160 locations in 46 countries throughout the world. A Russian court charged twenty-eight Greenpeace International activists, as well as a freelance videographer and photographer, with piracy this week. The charges follow a peaceful protest against Arctic oil drilling at a Gazprom oil platform in the Pechora Sea.
