Overexploitation
The harvesting of wild species at rates faster than populations can replenish, identified by IPBES as a leading direct driver of biodiversity loss.
Definition
Overexploitation is the unsustainable harvesting of species from the wild — through fishing, hunting, logging, trade or gathering — at rates that exceed the capacity of populations to recover. Global assessments identify it as one of the largest direct drivers of biodiversity loss, historically the dominant driver in the oceans and second only to land-use change on land.

Overview
What it means
Overexploitation has driven countless species declines and extinctions, from whales and great auks to overfished stocks and trafficked wildlife today. It often interacts with other drivers: habitat loss shrinks populations that exploitation then pushes past recovery thresholds.
How it is used
The term is standard in conservation science and policy, including IPBES global assessments, IUCN Red List threat classification, CITES trade regulation and fisheries management.
Why it matters
Controlling overexploitation is among the most direct conservation levers available — through quotas, protected areas, trade controls and enforcement — and is central to the Kunming-Montreal Global Biodiversity Framework targets.
Review
Public comments appear only after editor acceptance. Draft comments stay in the review queue.
Reviewers choose the definition or an overview paragraph, leave a comment or replacement, and attach evidence or a source link.
Editors compare reviewer cards side by side. AI may help find agreement, conflicts, unsupported claims and possible source issues.
Only an editor-accepted synthesis changes the public page. Reviewer identities are shown only with consent and an editorial decision to attribute them.
Submitted reviews stay private until an editor decides whether to accept and attribute them.

Review board
Comment on a specific line. Each reviewer stays separate until an editor accepts a merged draft.
Each person comments on the definition or overview in their own draft card, with role, evidence and suggested wording kept together.
AI can compare comments against the current text, flag conflicting claims, surface missing evidence and identify where reviewers agree.
An editor merges compatible suggestions into a draft change, checks sources, records disagreements and decides what can be published.
