National Geographic is covering the publication of a new scholarly article about the diversity of languages on our planet and the catastrophic predictions about how many will be left at the end of the next century.
The scholarly article, written by David Harmon and Jonathan Loh, appears in the journal of Language Documentation & Conservation. The National Geographic article (linked below) features an interview with these two and with Luisa Maffi which highlights their Index of Linguistic Diversity (ILD), a calculation of how many language we have left and where they are.
In addition to the important work on language diversity and language distinction, this article also provides data about the language which are most commonly spoken. English is in third place, which might surprise some people.
