In this Letter, as a result of an inadvertent spreadsheet error, four values presented in Table 1 were slightly inflated. These relate to the proportions of Earth’s total land surface located within the ‘conserve’, ‘agriculture’, ‘conflict’ and ‘low-tension’ zones. The correct percentage values for these four zones under the ‘global’ heading are 42.96, 11.40, 15.34 and 30.30, respectively. Two of these values (the global percentages for conflict and agriculture zones) were also mentioned in the main text. We apologise for these errors, which have now been corrected in the online versions of the Letter, and do not affect the interpretation of our analyses.
