Former President Mary Robinson is among four former heads of state who have criticised the failure of world leaders to attend a major UN biodiversity summit in Canada next month.

The Campaign for Nature, which is a collaboration between the National Geographic Society and the Wyss Campaign for Nature, has described the Montreal Cop15 event from December 7 to 19 as a pivotal moment for nature and biodiversity.
