Sentinel Guest Commentary: 3 SC Councilmembers declare, "Now is the time to protect the Monterey Bay", May 7, 7 - 9 PM
To prevent drilling in Central California it is crucial to strengthen our local ordinances… in three ways: to integrate updated science to support the findings for why these uses are harmful to our community; to require voter approval for any onshore zoning changes needed to facilitate either offshore oil and gas drilling or deep-sea mining; and to explicitly prohibit any on-shore industrial activities that facilitate offshore oil and gas drilling or deep-sea mining, such as refining or trucking facilities, in industrially zoned areas. The first step in enacting this revised ordinance starts May 7 at the City’s Planning Commission meeting. We urge everyone who is concerned about this threat to our coast, our environment and our way of life to show up in support (809 Center St) or to submit your thoughts to cityplan@santacruzca.gov.

Rights of Nature Santa Cruz: Join our Team!
Rights of Nature is a growing legal and cultural movement that recognizes ecosystems — like rivers, forests, and oceans — as living entities with inherent rights to exist, thrive, and regenerate. Instead of treating nature solely as property, this framework gives communities a legal tool to defend the natural world when it’s threatened. We are a grassroots working group pursuing a ballot initiative to grant local ecological entities legal rights to exist and evolve. We're currently researching which ecosystem or species — such as the San Lorenzo River, salmon, or wildlife corridors — should be the focus of the policy. We need researchers now, and will need help with communications and signature collection as we move forward. We hope you will join us. Please visit our website HERE.
