City Campaign. Plastic-Free Estuaries

• Engage local watershed councils, estuary managers, and coastal NGOs to acknowledge the documented accumulation of meso-, micro-, and nanoplastics in Los Angeles estuaries.

• Invite seafood vendors, marina operators, and community groups to review evidence on plastic pathways and commit to sharing simple pollution-prevention information with customers and residents.

• Encourage small businesses, waste-management units, and coastal recreation groups to endorse a non-binding “Estuary Plastics Awareness Commitment,” agreeing to promote source-reduction messages, proper disposal guidance, and visible signage near storm drains.

• Ask adopters to report low-burden actions—e.g., posting estuary-safe disposal tips, reducing plastic packaging, or supporting local monitoring volunteers.
