Title says it all.
All credit goes to the photographers of these amazing pictures.
Edit: I've made a part two, by adding the reminder of the pictures from Buzzfeed, plus some i've found by my self. funnyjunk.com/funny_pictures/2986690/2011+in+pictures+part+deux/
Edit edit: I've got the pictures from Buzzfeed's most powerful photos of 2011 - i've created this comp to share it with my fellow Funnyjunkers, and i'm really sorry about forgetting the picture(s) from the Utøya/Oslo tragedy. And the other pictures i've left out.
