CBD Blog THC: It is with great regret and deepest sadness that we convey news of the untimely death of Dr Bradnee Chambers, Executive Secretary of the Convention on Migratory Species (CMS). Among his numerous achievements is the strengthened collaboration among the biodiversity-related conventions towards common objectives. His loss will be felt by each of them. He was an extraordinary advocate and champion for the environment, and a kind and wonderful human. His friends and colleagues at the Secretariat of the Convention on Biological Diversity would like to express their deepest sympathy to his family and to all staff at the CMS Secretariat.
