Bay Ecotarium dba the Bay Ecotarium is the largest watershed conservation organization in San Francisco and is an amalgam of six institutions, united under one mission to protect and conserve the Bay Area ecosystems. Human impact and environmental changes have put a strain on the ecological balance, and the Bay Ecotarium works towards preserving the natural environment for future generations. We focus on changing the conversation about conservation from a position of scarcity to that of abundance and from fear to opportunity.
