Human Languages Decline as Species Disappear

Biologists estimate annual loss of species at 1,000 times (or greater) of historic rates. Linguists predict that 50–90% of the world’s languages will disappear by the end of this century.

A new paper in PNAS finds that 70 percent of the world’s languages are found within Earth’s most biologically diverse regions.

Earlier studies suggested there was probably a lot of overlap between areas of high biological diversity and areas of high linguistic diversity. But data were limited.

In the new study, the authors used recently compiled global data showing the geographic locations of more than 6,900 languages compiled for geographic information system (GIS) applications by Global Mapping International. They used the locations of biodiversity hotspots and high biodiversity wilderness areas compiled by Conservation International.

Their findings:

  • The languages in biodiverse hotspots are frequently unique to their particular regions
  • Many of these endemic languages also face extinction

The researchers examined 35 biodiversity hotspots—locations with an exceptionally high number of endemic species, which have lost 70 percent or more of their habitat (top map, above). These hotspots comprise only 2.3 percent of the Earth’s surface, yet contain more than half the world’s vascular plants and 43 percent of its terrestrial vertebrate species. They also contain people speaking 3,202 languages—nearly half of all languages spoken on Earth (bottom map, above). 

“In the past, it was hard to get biologists to look at people,” says Gorenflo. “That’s really changed dramatically in the past few years. One thing that a lot of biologists and ecologists are now seeing is that people are part of these ecosystems.”

The team also examined linguistic diversity in five high biodiversity wilderness areas—places whose remaining habitat covers ~6.1 percent of Earth’s surface and contains about 17 percent of the vascular plants and 6 percent of the terrestrial vertebrate species. These biodiversity wilderness areas  are also home to people speaking another 1,622 languages. 

In many cases it appears that conditions that wipe out species wipe out languages,” says lead author Larry Gorenflo at Penn State Department of Landscape Architecture, and affiliated with Penn’s Institutes of Energy and Environment. “I think it argues for concerted conservation efforts that are integrated and try to maintain biodiversity and cultural diversity.”

From the paper:

Given the capacity of humans to dominate, and in many cases eradicate, other species on our planet, the importance of the relationship between people and the natural environments they inhabit cannot be overstated for biodiversity conservation. Unfortunately, the opportunity to enlist speakers of particular languages in biodiversity conservation is rapidly disappearing as languages are lost at an alarming rate. Although linguists have attempted to identify languages in danger of disappearance, no system of language ranking in terms of risk can claim the broad attention and authority enjoyed by the IUCN Red List, the main means of evaluating the conditions of species.

As for why the coexistence between areas with high concentrations of endangered species and endangered languages, the researchers aren’t sure. But possibly because indigenous cultures, supported by their languages, create conditions optimum to maintaining species and keeping ecosystems intact and working.

DOES IT FEEL LIKE POLITICS IS AT A BREAKING POINT?

Headshot of Editor in Chief of Mother Jones, Clara Jeffery

It sure feels that way to me, and here at Mother Jones, we’ve been thinking a lot about what journalism needs to do differently, and how we can have the biggest impact.

We kept coming back to one word: corruption. Democracy and the rule of law being undermined by those with wealth and power for their own gain. So we're launching an ambitious Mother Jones Corruption Project to do deep, time-intensive reporting on systemic corruption, and asking the MoJo community to help crowdfund it.

We aim to hire, build a team, and give them the time and space needed to understand how we got here and how we might get out. We want to dig into the forces and decisions that have allowed massive conflicts of interest, influence peddling, and win-at-all-costs politics to flourish.

It's unlike anything we've done, and we have seed funding to get started, but we're looking to raise $500,000 from readers by July when we'll be making key budgeting decisions—and the more resources we have by then, the deeper we can dig. If our plan sounds good to you, please help kickstart it with a tax-deductible donation today.

Thanks for reading—whether or not you can pitch in today, or ever, I'm glad you're with us.
