Thursday, May 16, 7pm via Zoom — Nayamin Martinez, Director of the Central California Environmental Justice Network (CCEJN) presents "Environmental Justice in the San Joaquin: What has happened and what YOU can do"

While California is a vibrant state, nearly four million residents living in the San Joaquin Valley continue to be disproportionately exposed to multiple hazardous contaminants, including unsafe drinking water, pesticide exposure and air pollution. In recent years, the COVID-19 pandemic, rampant wildfires, and historic flooding further compound inequalities and disproportionately impact frontline and marginalized communities. You will learn how CCEJN has been combating environmental injustice and promoting climate resilience.
