Is scientific language often too complex for average people to understand regarding urgent environmental crises?

A 2026 study published in npj Biodiversity analyzing data from July and August 2025 found that Americans react with significantly more concern to the term extinction of plants and animals than to biodiversity loss. Researchers surveyed 7,338 adults to determine how specific terminology influences public awareness and support for environmental policy.

Why it matters

Understanding how language influences public concern is critical for environmental communicators attempting to drive policy support. This research demonstrates that while technical terms like biodiversity loss often fail to resonate, clear descriptions of nature decline consistently align public sentiment with conservation goals.

In this survey of 7,338 adults, 82% of participants were familiar with the phrase extinction of plants and animals, compared to just 34% for biodiversity loss. Adding the word crisis to these terms yielded negligible changes in public concern levels.

The players

Walter Rosen

The biologist who coined the term biodiversity in 1986.

The details

Researchers recruited participants through the Understanding America Study to view one of six variations of nature-decline terminology. They employed both text-only prompts and image-text combinations to test recognition and concern. The study found that providing a short explanation of the environmental process consistently increased participant concern, effectively narrowing the gap between technical jargon and common language.

1986: Biologist Walter Rosen coined the term biodiversity.
2019: European Commission survey measured public knowledge of biodiversity.
July and August 2025: The Understanding America Study survey was conducted.
2026: Study published in the journal npj Biodiversity.

The Tech Race

This research updates the 2019 European Commission findings, which showed 41% of Europeans could define biodiversity. The current study suggests that despite decades of academic focus on the term, American public awareness of biodiversity loss lags behind traditional extinction-based descriptors.

This research does not immediately change individual behavior but signals that environmental advocates may adopt clearer language to increase public engagement. Readers can expect to see more direct phrasing in climate and conservation campaigns as organizations align their messaging with these findings.

The takeaway

Public support for land and water protection remains high at 84% to 95% regardless of the specific terminology used in outreach. Observers should track if future conservation campaigns shift away from biodiversity terminology in favor of more evocative language regarding extinction.
