Importance of Planet Earth

Planet Earth is the planet where we live and inhabit. If one were to think of everything that our planet contains, in the number of species that coexist, in the monumental works that man has created in him, he ends up realizing that the Earth is immense and that it offers a perfect balance in how much nature, which unfortunately man has been in charge of manipulating even when it is known that such manipulation brings serious problems endangering species of living beings, as is happening with species vegetables and animals.

The Earth has a round shape, due to the force that the Sun exerts on it, and it is around the Sun that the Earth rotates in a translation movement that lasts 365 days (the days that the year lasts).

In addition, the Earth also performs a motion of rotation, by which it revolves around its own orbit, and has a natural satellite, the Moon, that revolves around the Earth attracted by the force of gravity that our Planet on it exercises.

So far, Earth is the only planet in the Solar System on which life develops, although scientists have been studying it for years. investigate whether the development of living beings may be feasible on other planets in the same System, especially looking for evidence of the existence of water and also taking into account the gravity of each one of them, which is what allows us, who live on Earth, to be on it settled and not floating through the air, as for example if it occurs on the Moon, and that was clearly seen when North American astronauts reached it in 1969 to explore it.

The Earth has different elements in its composition that form the whole set: for example, the biosphere is made up of all the living beings (humans, plant species and animal species), while the hydrosphere is that part that has as its composition principally all the masses of water found on the planet: lakes, seas, rivers, large icebergs (water in solid state or ice), among others.

The question about when Planet Earth was formed or originated has been the axis and center of debates, polemics and conflicting positions among thinkers and scientists from all branches of science and diverse disciplines

The truth is that the Earth began its origin more than four thousand five hundred million years ago, although the existing life on Earth arose much later, approximately a billion years back. As a "house" of life, it is still today the only body in space known to be capable of hosting life.

Just as the origin of the Earth sparked numerous debates and investigations, so has the fact of its "useful life", that is, until when will Planet Earth "live" was also a center of speculation, research and reflections. In this sense, some scientists believe that the Earth will be capable of hosting life for another half a billion years, at which time it is expected that the radiations emanated by the Sun are much stronger than they are at present and begin to deteriorate the terrestrial biosphere until it disappears this.
