Xerxes Foundation supports people and organizations working toward abundant clean energy, a healthy climate and oceans, clear and open minds, and strong local communities.
Herodotus tells of Xerxes finding a plane tree on the road to Sardis, so beautiful that he honored it and appointed a guardian to look after it, one after another, without end.
