Tishah b’Av, the ninth day of the month of Av, has historically been a day to mourn the Destruction of the First and Second Temples, centers of Israelite practice before the rise of Rabbinic Judaism (First Temple 975 BCE – 586 BCE; Second Temple 515 BCE – 70 CE) and the exiles that followed those destructions. Over the course of Jewish history this day of mourning and fasting has also come to commemorate many other tragedies that have befallen the Jewish people throughout history. This year we are beginning a new tradition. We are suggesting that in addition to, or instead of (depending on the norms of your community and personal practice) the traditional observance of Tishah b’Av, the time has come to use this powerful day to mourn the ongoing destruction of the “temple” that is our Earth, a tragedy for all peoples, creatures and living things, but one that is not complete and thus, with sufficient will and action, is in part, reversible. . . .
