Images of cattle grazing and farmers herding their livestock in Brazil, the world's largest exporter and second largest producer of beef. Seen from the sky, the Amazon is an endless expanse of deep green, a place where life explodes from every surface, broken only by the blue rivers snaking across it. Endless, that is, until it isn't. Fly toward the edges of the world's biggest rainforest, and you will come to the vast brown scar tissue, the places where the jungle is being razed and burned to make way for roads, gold mines, crops and especially cattle ranches.
