In this image, you can see one of the largest iron ore mines worldwide: the Carajás Mine. In the Carajás Mine, minerals are being removed from the surface layer by layer. In 2007, 296 million tons of iron ore were extracted. The Carajás Mine is estimated to hold approximately 18 billion tons of iron ore, gold, manganese, copper and nickel. In this image, the contrast between the red earth of the surface mining and the surrounding rain forest is striking. On the periphery of the image, you can see that rain forest has been cleared in favour of cultivated land.

This image shows an area in North Rhine-Westphalia spanning 30x36 km. The numerous rectangular areas depict agricultural plains. Bright shades of green signal plant growth, dark shades of green stand for forests and shades of grey indicate bare ground. Settlements are characterised by the accumulation of blue and grey pixels connected by thin lines (streets). The three large areas standing out due to their bright white and dark blue colour are the three big lignite surface mines in Garzweiler, Hambach and Inden.
