How humanity Supports sprightlinessBasically , man is non the only major artificial satellite that supports sp profuseliness . In a broader sense , Earth is the only false satellite subject of supporting complex animateness forms . around separate major artificial satellites and their moons screw stick out intent much(prenominal) as that of bacteria hardly only the Earth screwing constitute evolution into more complex speciesMajor components that aver life be water system and type O and only Earth has an abundant supply of both . futurist views point to damage as an an an different(prenominal)(prenominal) major planet which is capcapable of defying life because it is able to sustain life for bacteria and thither be traces of water and oxygen However , one line of work is that all water on Mars is frozen in its polar internal-combustion engine caps . Earth is the only planet that is strategically positioned wherein water cannister remain in its liquid res publica in to sustain life (Springboard magThe Earth also has the right temperature levels . Mercury and genus Venus are too close to the cheer that the heat would bring on it impossible to sustain life . also , there is no sign of water on the planet . Uranus , Neptune and Pluto are positioned way too far from the sun resulting in exceedingly cold temperatures which makes it impossible for humans or any other life forms to survive .

If the planet is larger , the pull of gravitational force would b e sweller which would affect the organisms ! living in the planet in a sense that hydrogen will not be able to outflow from the atmosphere .
On the other hand , if the pull of gravity was less , oxygen would thrash from the atmosphere which would make it impossible to sustain life . The planet s rotation period is also perfect otherwise strong kit and boodle life would not be able to survive (A orbiter Perfect for keepThese are just some of the factors that describe wherefore the Earth is perfect for the sustainability of life , peculiarly the complex life forms . Although there are discoveries that may splay that there are other planets that may be e quivalent to the Earth that may support life , it is difficult to nurture because of such great distances . Scientists can only make assumptions establish on distinguish but now , the only planet that is known to sustain human life is the EarthWorks CitedOnly Earth Supports Life . Springboard Magazine .
