Most of us think
that people are the most important things on earth, but we aren’t. We are
really much less important than plants! If all the people on earth die
tomorrow, life will not stop. The
plants, animals and everything else will go on living. But, if all the green
plants die, Earth will become a very different place. The air will change and
neither animals nor people will be able to live in that air.
All living things need plants to make the right kind
of air. But they also need them for something else --- food. Living things need
food to grow, but only plants can make their own food. Green plants get light
from the sun and water from the ground and turn it into food. Nothing else can
do that!
