Why urchin dye?

  • Purple sea urchins have eaten 95% of the kelp along the California coast.

  • The urchins are not the villains; rather, human-caused climate change created the “urchin problem.” 

  • Kelp forests can sequester up to 20 times more carbon per unit area than land-based forests. 

  • Kelp is home to thousands of different oceanic species.

  • Creating natural dye from sea urchins creates an incentive for the removal of sea urchins from the oceans.

  • Urchin dye is a way of honoring these magnificent creatures rather than discarding them.
