Etymology
Origin of ecosphere
Explanation
The ecosphere is the area on and around the earth where life exists. Organisms can only survive outside the ecosphere in an artificially protected environment, like a spaceship. Ecosphere is another word for biosphere — the area around a planet that contains everything that's needed to sustain life. In the case of Earth, that means oxygen and the other elements required for organisms to survive. Astronomers have a somewhat different definition of ecosphere which includes areas where life might potentially exist. The word was coined in the mid-20th century, from eco-, "the environment," and sphere, "space."
