Zoroastrism

Zoroastrian theology includes a duty to protect nature. This has led some to proclaim it as the "world's first ecological religion." Scholars have argued that, since the protections are part of a ritual, they stem from theology rather than ecology. Others have responded that, since the scripture calls for the protection of water, earth, fire, air, as once of its strongest precepts, it is, in effect, an ecological religion: "It is not surprising that Mazdaism (another term for Zoroastrianism) is called the first ecological religion. The reverence for Yazatas (divine spirits) emphasizes the preservation of nature (Avesta: Yasnas 1.19, 3.4, 16.9; Yashts 6.3-4, 10.13)."
