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.

    food for animals and people. Human beings
    receivex from animals butter, wool, dairy
    products. We receive wood, fuel, cotton, fibers
    from the plants. If we use our resources
    property, 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 gasesoxygen that we breathe
and is necessary humans and animals and carbon

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

oceans,seas, rivers, lakes.

The water continually makes it evaporates,
precipitates, flaws away.
The sun warms up the laund and vaporizes the
water. The steam up swims and clouds it
gathers. clouds onerturn themselves rain, snow
and hail and so they return to the ground again.

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.

would not be life without on the vital force of
water, the light and heating of fire, the
nutritional substances from the earth, the clean
air that we breathe. We must use them carefully
and keep our planet clean.
