Growing cities, overuse of fertilizers and factory wastewater have degraded China's water supplies to the extent that half the nation's rivers and lakes are severely polluted. China aims to spend $850 billion to improve filthy water supplies over the next decade, but even such huge outlays may do little to reverse damage caused by decades of pollution and overuse in Beijing's push for rapid economic growth.

A freediver uses weights, yoga and camera tricks to create the illusion of walking underwater for a film which took three years to shoot and was completed in 2013 in El Hierro, Canary Islands. Like a scene from a Hollywood science-fiction movie, this trick footage shows a man apparently walking on water. The underwater film was shot by biologist Armiche Ramos and brothers Armando and Francisco del Rosario, who used their expertise in freediving to create the illusion. No computer graphics were involved in the production, with the team relying solely on their own skills – and a few hidden secrets. (Photo by Ocean Brothers/Barcroft Media/ABACAPress)

Freelance illustrator and graphic designer Aurélien Police was born in France in 1978. He has already worked and is currently working on projects for the music and publishing industries (book covers, CD design, children book illustrations). He uses computer as melting pot to mix up all sorts of raw materials, erasing the frontiers between all possible media so as to provide his pictures with a graphic finishing of his own. Flirting with various themes -often associated with fantasy, detective or supernatural- allows him to translate in pictures his own personal vision of those genres.
