 Simone Cardona, Council Co-Chair


Hi I’m Simone Cardona, and I am Council Co-Chair for the 2014 cycle. I graduated in 2014 from UC Santa Cruz with Environmental Studies and Sociology.  As a student I was actively involved in many sustainability and arts organizations. I was an intern with UCSC’s Sustainability Office, co-facilitated a class with the Education for Sustainable Living Program, worked with the Common Ground Center providing students with tools to get involved, organized to protect our upper campus from development, and worked with Energy Service Corps and CALPIRG for two years. I was involved in a group of autonomous students during the Occupy movement planning direct actions for a just and affordable education system.i have always been simultaneously involved in social justice and arts communities  because I am interested in building movements through networks of artists and activists. I was an organizer with a multicultural performing arts group Rainbow Theater, and spoken word organization Kinetic Poetics Project hosting open mics, poetry slams, and the largest collegiate poetry festival in the country. I have a strong interest in political ecology, identifying and challenging the powers and systems that perpetuate environmental degradation. I also enjoy natural sciences, horticulture, conservation, and exploring the outdoors. Now I am pursuing work organizing on climate, energy, environmental and social justice. I am deeply passionate about the environmental movement, and working on campaigns and actions that challenge existing systems and offer solutions for a more just and sustainable world.

 Timmy Jacobs, Website Editor and Blog Editor

Timmy is currently a 4th year geography and environmental studies major at UCSB and will be CSSC’s website editor for this cycle. Timmy’s involvement in activism and the sustainability movement began through working on the fossil free campaign at UCSB. He quickly caught the activism bug and shortly after joining fossil free, he volunteered with the Santa Barbara Water Guardians, petitioning to get a fracking ban on SB County’s September ballot. He first got involved with CSSC while volunteering and attending the convergence at UCSB in spring 2014. I’m super stoked to be a part of CSSC and looks forward to all the exciting things we will accomplish this year.
