World Atlas of Coral Reefs

evidence

Global shallow coral reef area is on the order of a few hundred thousand square kilometres — under a tenth of one per cent of the ocean surface — while supporting a very large share of marine species. V55 verification basis: not consulted; the atlas's often-quoted global area figure (about 284,300 square kilometres) is stated from the producing model's knowledge. Later satellite mapping has produced substantially different totals on different definitions, and that discrepancy could not be reconciled here.

A evidence is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
