Whale Poop Is Climate Infrastructure
~33 tons of CO₂ captured per great whale, worth ~$2M lifetime (IMF estimate)
Whales dive deep, feed, and surface to release nutrient-rich fecal plumes — the 'whale pump' documented by Roman & McCarthy in PLOS ONE — feeding the phytoplankton that pull CO₂ out of the sky. An IMF-led analysis put the carbon value of an average great whale at roughly $2 million over its lifetime. Protecting whales isn't just sentimentality; it's atmospheric engineering that already exists.
A great whale fertilizes the ocean with iron-rich poop, triggering plankton blooms that lock away carbon — IMF researchers estimate each great whale captures ~33 tons of CO₂.
