Columba González Duarte, PhD, is a Mexican sociocultural anthropologist who studies the interaction between monarch butterflies and the human populations they encounter on their yearly migration across North America. Her main interest is in building environmental ethics beyond borders, and her project “Convergent Migrations” has an activist dimension through which she hopes to foster eco-social justice for humans and other animals in migration. She publishes in academic and non-academic venues regularly and is currently writing a book provisionally titled Tied Mobilities: An Ethnography of Human–Butterfly Migration in North America.
