The astronauts, who first saw the Earth from space, enthusiastically respond to the unique colors and patterns that dotted the planet. Green valleys, flower plantations, golden deserts, mountain ranges, as well as deep canyons. For millions of years, nature has created and changed landscapes that people in all corners of the world admire.
But for some time now man began to interfere in this creative process. Sometimes well-designed projects by scientists give life to drylands, and agricultural activity develops in just a few years. But also without stopping there is an extraction of ores and precious metals, as a result of which many "unplanned" holes have formed on earth. We suggest you take a small virtual trip to these places —10 Man-Made Black Holes on Earth
