Taking Down Goliath: Climate Organizing Training for 18-32 Year Olds

Taking Down Goliath is a climate-focused community organizing training specifically for Jewish 18 to 32 year olds. All are welcome to nominate someone.

Why us? Because we are the ones inheriting the planet and the climate crisis. Because social movements throughout history have been propelled by younger generations. Because as Jews, we can do more to organize our communities to address the climate crisis and bring about justice.

What will we learn? We’ll learn about strategy for building social movements, theory and practice for creating successful campaigns, and make a plan for ongoing organizing on your campus or in your community, including joining or starting a Dayenu Circle or taking action with a current campaign.
