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.

Sébastien Del Grosso is a French artist and a photographer, who will allow you to enter the world of surrealism, which combines photography and hand-drawn art. His works masterfully blur the transition between the real photo and the picture. By viewing his works, we can see that Sébastien is not only a master of creating photo illusions, but also a person who tries to show his inner world through his art. His emotions, his feelings, his fears and desires are all vividly and skillfully expressed in simple strokes of a pencil. He is the continuation of his art. So much so, that he loses his identity, fearing it, but being unable to stop. (Photo by Sébastien Del Grosso)
