We have an obligation to live in harmony with God's creation.
- Bruce Babbitt

is your legacy to future generations.

Treat the earth well.
It was not given to you by your parents,
it was loaned to you by your children.
We do not inherit the Earth from our Ancestors,
we borrow it from our Children.
- Native American traditional
A man is ethical only when life, as such, is sacred to him,
that of plants and animals as that of his fellow men,
and when he devotes himself helpfully to all life that is in need of help.
- Albert Schweitzer
Be gentle with the earth.
- Tenzin Gyatso, the 14th Dalai Lama
