A polar bear whose bottom half is caked in oily black gunk. A whale wrapped in striped fabric: a pseudo straightjacket. These are the messes climate change leaves behind, the things we know are happening but often don’t have the opportunity to see with our own eyes. Swiss street art duo Christian Rebecchi and Pablo Togni, otherwise known as NeverCrew, met in art school when they were 15 and started making work together soon after. As a team, the artists adorn the world with eye-popping and gut-wrenching images depicting the consequences of humanity’s actions on earth. (Photo by NeverCrew/The Huffington Post)

“These are the stunning shots of one photographer who is putting everyday “selfies” to shame. Paul Zizka, 34, began experimenting with night photography just two years ago and immediately became fascinated with the spectacular scenes he discovered. To create something more unique he started adding himself into the shot – as well as showing others the beautiful surroundings he had been exploring. Using lengthy exposure, the photographer felt that featuring himself in some of his shots – the night sky illuminating the mountains around him – created a relationship between the central figure in the image and the nature around him”. – Caters News.

Local villagers ride a local coal powered steam train on March 27, 2015 at a station in the town of Shixi , Sichuan Province, in Southern China. While China boasts the world's most extensive high-speed rail infrastructure with over 16,000 kilometers of track, the Shixi-Bagou railway is still a primary connection for local villagers between towns and is kept alive by tourist cars carrying passengers for ten times the price. The rail line came into service in the late 1950s and the train was initially used to transport coal from a now-shuttered mine before passenger carriages were added.
