Historical data on the areal extent of wetlands are highly uncertain, but an estimated 87% of the world's wetlands were lost in the past 300 years, 54% since 1900, and 35% since 1970.
“Historical data on their areal extent are highly uncertain, but an estimated 87% of the world's wetlands were lost in the past 300 years, 54% since 1900 (47), and 35% since 1970 (48).”

The most important human drivers of wetland decline are urbanization, drainage for agricultural expansion, and increasing use of irrigation in agriculture causing wetlands to dry.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
