Our Planet, the Earth

All of us live in the same magical and wonderful place, The Earth.

Our planet is the third of Solar System and so far the only one where life exits. The Earth is the largest telluric planet with one satellite, the Moon. It has surface area with 510,072,000 km² and 1.0832073×10¹² km³ of volume. The Earth has an atmosphere with Nitrogen (78, 08%), Oxygen (20, 95%), Carbon Dioxide (0,038%) and Water Vapor (about 1%), among others. This atmosphere is conducive to life and it is because of it there we live. The Earth has an average temperature of 15º Celsius, the rotation period of 23.9 hours and the translation period of 365 days and 6 hours. In our planet there are six continents, but 71% of it are oceans.

Like all the Solar System, the Earth is very old with about 4600 million years, but the life of human beings on this planet came to only 2.5 million years ago.

Human beings have inhabitted Earth for a short time but it seems that they will end up with life on this planet. Due to the pollution, global warming and extinction of species caused by the human activities, the Earth is exhausting all its natural resources and the conditions which are favourable to existence of life. In the future the Earth will probably be an empty and gloomy planet, like all other planets in the Solar System and life will cease to exist forever.

In my opinion the Earth is not a simple planet in the Universe, it is our home, the only place where we can live and forge relationships with different living beings. The Human Being has a mission: to take care and preserve Earth and not to destroy it. That way, all of us will live together and in harmony with the Earth for as long as possible.
