Look for us there!

Science Discovery will be out in the community throughout Earth Month on behalf of IWMA at select events, including SLO EarthFest on April 18, Cambria Earth Day on April 19, Cal Poly Green Campus Earth Week on April 22, and the City of SLO Farmers Market on April 23. Stop by the booth to say hi, ask questions, and pick up helpful resources.

Can’t make it to an event? A simple Earth Month goal is to do one “waste win” a week: check the Waste Wizard before tossing items, refresh your recycling setup at home, and consider composting food scraps to reduce what goes into the landfill.
