Our deep respect for the earth, plants, animals and the people.

Plants must rely on the earth for sustenance.

Animals must rely upon the earth, plants and other their kind just as we rely on all-earth, plants, and animals.

We must respect what is around us and give our environment our highest regards because without the plants and animals we would not survive.

We have just one earth!!
