                 The role of plants on the Earth.
We want to tell you about the role of plants on our planet.
Plants are very important to people. For man to live it is necessary to not only sleep, drink and eat but to breathe, too. If we do not breathe for at least a minute, we may die. Plants reproduce oxygen, forming the planet atmosphere. But we do not take care of our planet and the plants die. It is therefore possible that in a few thousand years we also may die.
So, let's take care of our planet and protect plants. And if we save trees, etc, we shall save ourselves. Thank you.
