These Photographs From Space Show What Humans Have Done to the Earth
Excerpt:
Space travelers have struggled to explain exactly what it is about seeing the planet as a pale blue dot that evokes this feeling. Yet artists, filmmakers and other Earth-bound creatives have been inspired by what the astronauts can share. Author Benjamin Grant, who just released a book, Overview: A New Perspective of Earth, that draws on the rich photographic resources collected by satellites, is the latest person striving to convey the feeling.
Here are a few of the photos:
Gemasolar Thermasolar Plant, 37.560755°, –5.331908° This image captures the Gemasolar Thermosolar Plant in Seville, Spain. The solar concentrator contains 2,650 heliostat mirrors that focus the sun’s thermal energy to heat molten salt flowing through a 140-metre-tall (460-foot) central tower. The molten salt then circulates from the tower to a storage tank, where it is used to produce steam and generate electricity. In total, the facility displaces approximately 30,000 tonnes of carbon dioxide emissions every year.

Iron Ore Mine Tailings Pond, 46.407676°, –87.530954° Tailings are the waste and by-products generated by mining operations. The tailings seen here were pumped into the Gribbens Basin, next to the Empire and Tilden Iron Ore Mines in Negaunee, Michigan, USA. Once the materials are pumped into the pond, they are mixed with water to create a sloppy form of mud known as slurry. The slurry is then pumped through magnetic separation chambers to extract usable ore and increase the mine’s total output. For a sense of scale, this Overview shows approximately 2.5 square kilometres (1 square mile) of the basin.
Arlit Uranium Mine, 18.748570°, 7.308219° The Arlit Uranium Mine is located in Arlit, Niger. French nuclear power generation, as well as the French nuclear weapons programme, are both dependent on the uranium that is extracted from the mine—more than 3,400 tonnes per year.
