According to the Library of the Ancients, it is said to have been reported; ""Zoroastrianism is, first and foremost, a environmentalist religion. The purity of the earth, water and air is paramount to the founding precepts and the adherents are bound, by scripture, to protect nature in all its glory. This is also evidenced by Zoroastrianism's specific holidays, which fall on the equinoxes and solstices, as celebrations of the natural cycles of the earth.
Basic Zoroastrian precepts
Equalism: Equality of all, irrespective of gender, race, or religion.
Respect and kindness towards all living things.
Condemnation of the oppression of human beings, cruelty against animals and sacrifice of animals.
Environmentalism: Nature is central to the practice of Zoroastrianism and many important Zoroastrian annual festivals are in celebration of nature: new year on the first day of spring, the water festival in summer, the autumn festival at the end of the season, and the mid-winter fire festival.
Hard work and charity: Laziness and sloth are frowned upon. Zoroastrians are encouraged to part with a little of what would otherwise be their own.
Loyalty and faithfulness to "family, settlement, tribe, and country.""
Paganism, by most any definition.
