Watching this “ambiguous animation painted on public walls,” you soon forget you’re seeing stitched together images of graffiti and lose yourself in the mesmerizing mutations.

The Athabasca Oil Sands, Alberta, Canada. These oil deposits make up the largest reservoir of crude bitumen in the world, and as recently as 2006, produced over 1 million barrels of crude oil per day.

Confluence of the Rio Uruguay and a tributary, Misiones province, Argentina. Drastically cleared to make way for farming, the tropical rainforest of Argentina is now in some areas a less effective defense against erosion than it was in the past. The heavy rains in the province of Misiones (79 inches, per year) wash the soil and carry off significant quantities of iron-rich earth into the Rio Uruguay, turning the waters a dark, reddish color. Carried by the river, this sediment is dumped in the estuary of the Rio de la Plata – the largest on Earth – and accumulates in the access channels to the port of Buenos Aires.

Waste from the copper mine at Chuquicamata, Chile. This giant scallop shell is made of earth. A crane deposits the earth in successive, slightly curved lines giving the appearance of sheets of sand lined up side by side. This earth is extracted with the copper, but it is separated from the ore by sieving. The metal is refined in the Chuquicamata foundry that, thanks to newly installed equipment, can now filter out 95 percent of the sulfur dioxide (SO 2 ) and 97 percent of the arsenic that the process releases.

Worker resting on bales of cotton, Thonakaha, Korhogo, Ivory Coast. Cotton crops occupy approximately 335,000 square klilometers worldwide, and use nearly one quarter of all pesticides sold.

Sand dune in the heart of vegetation on Fraser island, Queensland, Australia. Fraser Island, named after Eliza Fraser, who was shipwrecked on the island in 1836, is the world’s largest sand island. On top of this rather infertile substratum, a humid tropical forest has developed in the midst of which wide dunes intrude, moving with the wind. Fraser Island has important water resources, including nearly 200 freshwater dune lakes, and has varied fauna such as marsupials, birds, and reptiles. Welcoming 200,000 visitors a year without damaging the local fauna and flora is a real challenge to sustainable development on the island, which was declared a World Heritage site by Unesco in 1992.
