Watsonville Earth Day & Day of the Child 2024

When: Sunday, April 21, 2024, 12-4 pm
Where: Watsonville Plaza – 58 Main St., Watsonville

Earth Day 2024 will be a celebration of the earth and a place to inspire our community to preserve its health and well-being for our children and future generations.

This year’s theme, “Planet vs. Plastic,” is a call to action to increase awareness of the health risks of plastic and advocate for a reduction in plastic pollution. With the ongoing climate crisis, we also recognize the value of continuing to inform residents about its effects on our community and how to adapt to the changing conditions.

During this event, we want to help residents understand the impacts of plastic pollution and provide the resources they can use to phase out single-use plastics. We also would like to share with participants the actions they can take to reduce their carbon footprint and be more resilient to climate change.

Our vision is that attendees will leave the event inspired with the information, tools, and resources of how they can adapt their everyday actions to reduce their use of plastic, reduce their carbon footprint, and become more resilient to the climate crisis.

At the event, local organizations will offer:

  • bilingual education and activities
  • resources for families addressing different aspects of climate change, climate resilience, and reducing their use of single-use plastic

Attendees will have an opportunity to:

  • Participate in games and activities relating to climate action and climate solutions
  • Learn about local resources to reduce their carbon footprint and become more resilient to climate change
  • Be inspired to take part in our local efforts to make Watsonville more resilient to climate change

Open to everyone & free

This event is family-friendly and free of charge. To keep everybody safe, please do not come if you are feeling sick. Otherwise, we hope to see you there!
