Welcome to Terralingua!


Sustaining biocultural diversity — the true web of life.


For the past 25 years, we’ve been promoting understanding, appreciation, and support of biocultural diversity — the vital diversity of life in nature and culture.


Biocultural diversity is a living network made up of the millions of species of plants and animals that have evolved on Earth and of the thousands of human cultures and languages that have developed over time.


We believe that the world’s biodiversity, cultural diversity, and linguistic diversity are interdependent, bound together through the myriad ways in which people have interacted with the natural environment, and that sustaining biocultural diversity is essential for a healthy, just, and resilient future of life on earth.


And that’s why we are raising awareness about the converging extinction crisis of diversity in nature and culture and seeking to inspire a global biocultural extinction rebellion to counter that loss. Learn more about biocultural diversity.
