What about the Planet?

"Our" planet Earth has been there a long time ago before the living creatures of the Nature appear on it.

Of course our planet formation and also our star (the Sun) and galaxy ( Milky Way ) are all objects of the Nature itself and no matter if we don't really understand it.

Is necessary to preserve and protect our house, the planet and all the known nature processes and creatures. If we fail there are a lot of possibilities to affect the Nature in a way that we really don't understand and could suppose a lot of problems including the extinguishing of some of the nature processes or creatures.

The size of planet Earth is not really big but there are a lot of biodiversity and different scenarios for live. Another criteria or hierarchy levels are the scale... since carbon atom is the "glue" for molecules related to live, water molecule is the headstone for known biodiversity.

For facilitate the classification and simply the synergies the Planet main theme have to be divided into sub-themes. These classification is not closed, could change and evolve in any desired or necessary way.
