During his recent visit, he met an Iranian-born, Brooklyn-raised food blogger. She now calls Tehran home, and writes a blog about Persian food called "Fig and Quince."

Today we bring you a profile of a woman who's been protesting a huge hydropower dam near her house for nearly 30 years, and she's hoping to inspire a new generation of activists.
