We live on a planet, called Earth. We are allowed to live here, because of the strength of the sun. But not only the sun brings us the sun's rays day after day - the wind, the water, the Earth's interior and the plants give us their energy without us having to pay anything every day. Sunbeams costs us any money. The wind also requires nothing to suggest that he bears the kites of our children into the air. There is a diverse of water in large quantities and plants grow quickly, if we take good care of it. And the earth: it gives us warmth - for no reason. We live on the planet, called Earth.
