In this video, 18 year-old Oregonian Kelsey Juliana is interviewed about her life-long journey of activism on climate change issues. Following in her parents’ environmental activist footsteps, she was invited by Our Children’s Trust to take part as co-plaintiff in a major lawsuit that could force the state of Oregon to take stronger action against carbon emissions, the cause of global warming and natural disasters. This legal strategy aims to protect the atmosphere based on the public trust doctrine developed by Mary Christina Wood in her book Nature’s Trust. Wood advocates that government should be accountable for any failure to protect the environment and resources that are held in public trust and needed for citizens to survive. Besides the legal route, Kelsey took part in the Great March for Climate Action across America, reaching Washington on 1st November for the UN global summit on climate. Video Capture: Bill Moyer
