"'Genesis' is a new exhibit of more than 200 black-and-white images from the noted Brazilian photographer Sebastiao Salgado. He wants to show us what the world and its peoples look like now, how climate change has already had an impact — and what might be lost if Earth's climate continues changing."

"His pictures will be on view at the International Center of Photography in New York City through Jan. 11. Goats and Soda is featuring four images that show parts of the world that our blog covers. We spoke with Salgado to learn more about his work."
