Our planet the Earth is a small close with a clear blue sky, oceans and seas, beautiful forests and lush meadows-the place soaked with life of plauts, animals and people. The air, the sun guarantee the life of plants.

Human beings receivex from animals butter, wool, dairy receivex from animals butter, wool, dairy products. We receive wood, fuel, cotton, fibers products. We receive wood, fuel, cotton, fibers from the plants. If we use our resources property, from the plants. If we use our resources property, they will never end.they will never end.

Everywhere around us there is air. We do not see it, but we feel it as wind – Going Air. The air is a mix of several gases;oxygen that we breathe and is necessary humans and animals; and carbon dioxide that plants breathe.

The air must be keept clean.In the forests the air is the cleanest in towns dirtier, because of the numerous chimneys and cars.

To make the air clean also in the cities, trees, shrubs and flawers planted. Walkabouts in the clean air consolidated the health of people and raise their spirit.

Our planet the Earth is known also as the Blue planet, because most of its surface is covered with water and if we look from the space,really appears blue.The water is the white gold for it is really worth while for natural life.

The largest part of our planets water is in oceans,seas, rivers, lakes.

The sun warms up the laund and vaporizes the water.The steam up swimsand clouds it gathers.clouds onerturn themselves rain,snow and hailand so they return tothe ground again.

The water continually makes it evaporates, precipitates, flaws away.

How is nice and warm near the fire.Who invented it?The ancients used it many years ago.At the beginning people were afraid of fire, but later they understood that it was really useful and learned how to light it on by rubbing two dry sticks one against the other.All along the centuries the fire helped all the people- for heating, lighting, preparing food frightening wild animals, delivering messages…

The sun is an ewormous fireball. On our planet there would life without its light and heating .

We have to use fire safely in order to avoid setting on fire woods.
