Canadian photographer Edward Burtynsky has an amazing ability to visualize the scale of the changes caused by human activity. Mountains of worn tires, oil fields and bright orange rivers flowing out of the nickel mine - these are just part of modern landscapes, both repulsive and frightening.
His photographs are part of the collections of Bibliotèque Nationale in Paris and the Museum of Modern Art in New York.In 2005 Burtynsky won the annual TED Prize and made a wish for his work to inspire global conversation on sustainability.
