Which of the following is a major source for Jewish environmental ethics?

The Book of the Tenakh, which is the canonical collection of Jewish texts, serves as a major source for Jewish environmental ethics. This collection includes the Torah, the Prophets (Nevi'im), and the Writings (Ketuvim). Within these texts, various principles and teachings reflect the significance of creation, stewardship of the earth, and the relationship between humans and nature. For instance, the concept of "Bal Tashchit," which prohibits unnecessary destruction, is often derived from interpretations of teachings found in the Tenakh.

In contrast, the other options do not belong to the Jewish tradition. The Sefer Torah is indeed part of the Tenakh, but it represents only the first section of it and does not encompass the broader ethical framework provided by the entire Tenakh. The Book of Mormon is a sacred text for members of The Church of Jesus Christ of Latter-day Saints, and the Quran is the holy book of Islam. Therefore, these texts do not formulate Jewish environmental ethics in the same way that the Tenakh does. This foundational text provides a comprehensive understanding that informs Jewish views on ecological responsibility and the ethical treatment of the creation.
