A new map of global bird diversity provides far more detail on patterns of distribution than was previously known. This is good on many levels, not least of which that scientific knowledge for its own sake is valuable. But to suggest as is frequently the case with such findings that this information should be used to target conservation is dangerous.

The Earth has far surpassed the amount of natural ecosystems that can be lost while sustaining life of all sorts. To suggest that these small albeit diverse areas should be more likely to be protected inherently dooms other much more widespread areas to continued degradation. This is unacceptable. If humanity is to avoid endangerment we need extensive areas of natural ecosystems to be protected and restored far beyond but perhaps including biodiversity hotspots.
