Flamingos are returning to Lake Uru Uru in the Bolivian highlands as it gets cleaner, thanks to the hard work of a group of young Indigenous women who call themselves the Uru Uru Team.

The team’s co-founder, Dayana Blanco, 25, is an Aymara woman who is a Fulbright fellow studying peace-building at the University of Massachusetts in the US.

Pollution caused by waste from the nearby city of Oruro poses a threat to the Indigenous community, local flora and fauna, and an internationally recognized wetland under the Ramsar convention.
