Women from all corners of the globe are organizing their communities to resist harmful development projects that threaten the health of river ecosystems. In this beautiful essay, we meet five water warriors: Larissa Elena, Dipti Bhatnagar, Anabela Lemos, Liane Greef and Caleen Sisk-Franco, who is a Tribal Chief and Spiritual Leader of the Winnemen Wintu Tribe. From Panama to Mozambique, these powerful women allow us to read their love letters to the rivers they fight to protect and to the communities of courage and resistance to which they belong.
