- Youth Use Video to Demand U.S. Government Protect the Atmosphere and Their Future I manage our U.S. partnerships at WITNESS. This year I've had an important opportunity to combine my passions for human rights and the environment while working to produce films with youth across the country and support an unprecedented legal effort. Through our partnership with the iMatter Campaign, I've traversed the country meeting and working with youth that have already been affected by climate change and are standing up to ask the ruling generation for change.
