'Intersectional environmentalism' is a) a lot of syllables, b) a brilliant concept explained simply and powerfully by writer and environmentalist Leah Thomas, and c) coincidentally also the title of Leah's new book.Part activist toolkit, part theory, and part history of environmental (in)justice, The Intersectional Environmentalist acknowledges and explores the overlap between systemic harm against Black, Indigenous, and people of colour (BIPOC) communities and the Earth.It also does a superb job of disentangling numerous knotty issues, like what privilege is and what it's got to do with the planet, with care and patience.And, talking of patience, Leah tells us that in a world overflowing with mansplain, her favourite pastime is "gracefully humbling men". The babble can neither confirm nor deny whether it was humbled during the course of this interview. (Yes, yes we were. Ed.)Sustainababble is your friendly environment podcast, out weekly.
