The wish, need or preference to pin down a precise official start date for the Anthropocene is curious. The boundary between the preceding epochs, the Pleistocene and Holocene, says Encyclopaedia Britannica, is “around 10,300 ± 200 years” ago. Perhaps it makes sense for the Anthropocene start date to remain uncertain, too (22 February, p 37).
