www.utzedek.org was launched today by Uri L’Tzedek (Awaken to Justice), leaders of the Orthodox social justice movement. There are tons of Torah sources, activist resources, events, volunteer opportunities, information on where to eat at Tav HaYosher (ethically certified) restaurants, and more.
Also, check out Shmuly, Uri L’Tzedek’s co-founder, getting arrested in protest of civil and human rights violations in Iran.
