Kelsey Juliana of Eugene, Oregon, has engaged in climate activism since age 10. When she was 15 she co-filed a lawsuit, with the support of nonprofit Our Children's Trust, against the Oregon State Governor, asking for a climate emissions reduction plan and to protect the atmosphere under the public trust doctrine. By 16, Kelsey was a trainer and organizer for the Sierra Student Coalition’s organizing camp. At age 18 Kelsey participated in the Great March for Climate Action, marching 1,600 miles from Nebraska to Washington, D.C. urging climate action from world leaders. In 2015, at 19, she submitted a Constitutional Climate Change lawsuit alongside 20 other youth against the United States Government. In this presentation she talks about the joys and challenges of this work as part of the Our Children’s Trust organization and gives advice for other young activists wanting to take action and still enjoy their lives.
