Rev7: After this I saw four angels standing at the four corners of the earth, holding back the four winds of the earth to prevent any wind from blowing on the land or on the sea or on any tree. 2Then I saw another angel coming up from the east, having the seal of the living God. He called out in a loud voice to the four angels who had been given power to harm the land and the sea: 3"Do not harm the land or the sea or the trees until we put a seal on the foreheads of the servants of our God."

She explains that the Four Corners area is particularly sacred because it literally holds Mother Earth's internal organs -- coal and uranium which the Bureau of Indian Affairs has allowed the Peabody Coal Mine to mine.

"They are trying to take her precious guts out for money," says Blackgoat. "My grandfather told me that coal is like the liver, and uranium is both the heart and lungs of Mother Earth."

The Four "spheres."

On the other hand, the four subsystems, or "spheres," within the larger Earth system are very much open systems. Of these four subsystems, the name of only one, the atmosphere, is familiar from everyday life, whereas those of the other three sectors (geosphere, hydrosphere, and biosphere) may sound at first like scientific jargon. Yet each has a distinct identity and meaning, and each represents a part of Earth that is at once clearly defined and virtually inseparable from the rest of the planet.

The geosphere is the upper part of the planet's continental crust, the portion of the solid earth on which human beings live and which provides them with most of their food and natural resources. It is also the oldest, followed by the hydrosphere, which had its beginnings with several hundred millions years' worth of rains that took place about four billion years ago. Today the hydrosphere includes all water on Earth, except for water vapor in the atmosphere. The latter, incidentally, was probably the last of the four subsystems to take shape: though Earth in its early stages had a blanket of gases around it, there was no oxygen. (See Paleontology for more about the early atmosphere, oxygen, and early life.)
