Earth is the home to millions of species [ 2] of organisms, including humans; it is the only place it is known that there is life in the universe . Since the Earth was formed about 4.54 billion Snhoukd life appeared on its surface in the last billion years . Since then , Earth 's biosphere has led to a change in atmospheric conditions is vital on the planet, which allowed the proliferation of organisms that live only in the presence of oxygen and be ozone, which works with the Earth 's magnetic field on the block harmful radiation layer, allowing the existence of life on the surface earth . Obscure ozone rays layer UV, works Earth 's magnetic field on the shift and keep coming from the sun - charged elementary particles greater speeds and kept them in outer space away from Earth, do not cause harm to living organisms . [ 7]
resulted in the physical characteristics of the land appropriate astronomer and orbit orbiting it around the sun as provide them with warmth, energy , and the presence of water to the origin of life and the continuation of life it until the current era . It is expected that life goes on on Earth for 1.2 billion years time, serving then rising sun on the Earth 's biosphere, where scientists that the sun will rise the temperature in the future and expand and grow up to become a giant red and a diameter of Venus , or even to the Earth 's orbit is believed to light , as they see the evolution similar to the sun in the universe of star when near the end of life of a star and the entry into force of its fuel of hydrogen . [ 8] then the high end of life on Earth the sun 's heat . If this being another event did not happen to her before that - such as an explosion nearby star in supernova greatest body - ending the life .
Various land resources works to keep the huge global population of humans, who divide the world among themselves , and are distributed to approximately 200 independent state, and interact with each other in a variety of ways , including diplomatic tourism , trade and military fighting communicate well . Appeared in human culture looks different representations of the Earth, some ancient civilizations embodied as a god, and some felt was flat, and others said it is center of the universe, now the prevailing trend states that this planet is an integrated environment require human supervision by the maintenance of the dangers that threaten it , and that that would threaten the man himself in the end .
