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

Conducted in July and August 2025, a new study reveals that American adults express significantly higher concern when confronted with the phrase extinction of plants and animals compared to biodiversity loss. This research highlights a gap in public familiarity and emotional response between common environmental labels.

Why it matters

Understanding which terms resonate with the public helps environmental advocates and policymakers craft messages that effectively communicate the urgency of nature decline. This study demonstrates that simple language can be more persuasive than scientific terminology in driving public engagement.

The survey analyzed responses from 7,338 participants regarding six different terms for nature decline, noting an 82% familiarity rate for extinction compared to 34% for biodiversity loss. Researchers found that while word choice shifted concern levels, 84% to 95% of participants supported land and water protection policies regardless of the terminology.

The players

Walter Rosen

He is a biologist who coined the term biodiversity in 1986.

European Commission

This is the executive branch of the European Union that conducts large-scale public surveys.

Understanding America Study

This is a probability-based internet panel used to recruit research participants from randomly selected U.S. addresses.

The details

Researchers utilized the Understanding America Study to assign participants randomly to one of six terms, with some groups receiving additional images or explanations to measure impact. Adding terms like crisis did not reliably boost public concern, but providing short explanations alongside the vocabulary consistently increased respondent worry.

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

The Big Picture

This study shifts the focus from purely scientific definitions to the psychological impact of environmental language on public policy support. By contrasting these results with the 2019 European Commission survey on biodiversity, it highlights a persistent gap between academic naming and public recognition.

The study suggests that future environmental messaging campaigns may see higher engagement by prioritizing clear, descriptive terms over technical jargon. This change could lead to more effective advocacy as groups look to build public consensus for land and water protection projects.

The takeaway

Using clear, evocative language is often more effective at capturing public attention than relying on complex scientific terminology. When advocating for environmental causes, focusing on recognizable terms like extinction can help generate greater public support for conservation initiatives.
