Garcia was one of the organizers of the People's Climate Movement "Rise for Climate, Jobs, and Justice" demonstration at the 2018 Global Climate Action Summit in San Francisco. As part of that action, she and other climate activists interrupted Governor Jerry Brown as he came onstage to give a speech.[7] They voiced demands for an end to new oil and gas drilling contracts in California, and asked Brown to account for the contradiction between his reputation as a political leader on climate issues and his continued support for fossil fuel projects.[8] Garcia was removed from the hall by security, along with two other women.[7]
Garcia has spoken publicly about the effects of climate change in her own life. During the disastrous 2020 fire season, she had to evacuate her home when it was threatened by the Almeda Fire in Oregon, and her father's home was destroyed.[9][3] She was one of the organizers of a bilingual commemorative community event on the first anniversary of the fire, which displaced thousands of local residents.[10]
In 2019 Garcia attended COP25 as the leader of a delegation of indigenous youth affiliated with the advocacy group SustainUS.[11] Other social justice organizations with whom she has worked include Earthjustice, Our Children's Trust, Honor the Earth, Greenaction, Rustic Pathways, Women's Earth Alliance and No More Deaths.[1][4]
Garcia is one of the lead organizers of Run4Salmon, a prayer journey led by the Winnemem Wintu Tribe and their Chief Caleen Sisk. Since 2016, Run4Salmon has sponsored a yearly journey along the migratory path of the Chinook salmon, from high-elevation spawning grounds in the freshwater McCloud River to the coastal waters of the Sacramento–San Joaquin River Delta. Participants travel the 300-mile-long route over the course of two weeks, raising awareness about the health of California's waterways biodiversity and the endangered status of the salmon, a keystone species. Along the way they host events that advocate for ecosystem restoration and celebrate indigenous lifeways.[6]
Garcia began a virtual reality film project about these issues and the Run4Salmon journey in 2020 after receiving funding from the United Nations. The educational film aims to make the beauty and the fragility of the McCloud River ecosystem more accessible and immediate to those who can't experience it in person.[12]
The Run4Salmon helps spread awareness about the Winnemem Wintu Tribe's project to reintroduce winter-run Chinook salmon to the McCloud River, using genetically descended stock that had been shipped to the Rakaia River in New Zealand in the 1940s.[12][6] The winter-run Chinook is nearly extinct after being cut off from its upstream spawning grounds by the construction of the Shasta Dam.[13] The effort is being undertaken in coordination with the Ngai Tahu Maori, the United States Bureau of Reclamation and the National Oceanic and Atmospheric Administration.[12][14]
