Your News feature on airborne environmental DNA (eDNA) suggests the technology could link “the whole [of] biodiversity, the whole world together with a single assay” (see Nature 652, 556–558; 2026). I welcome this optimism, but wish to highlight a paradox: the regions in greatest need of biodiversity monitoring are least equipped to deploy the technology in its current form.
