Rubenstein School environmental scholar and lecturer Walter Poleman attended the 16th United Nations Conference of the Parties (COP16) to the Convention on Biological Diversity in Cali, Colombia.

Walt attended COP16 as a member of the Vermont Biodiversity Alliance (VBA), one of a few U.S. groups granted observer status. While he was in Cali, Walt took up vlogging to document his experience and to show his students and the Rubenstein School community what it was like to be at the conference.
