Whale poo is like environmental gold dust. It is rich in iron, phosphorus and nitrogen, among the nutrients that phytoplankton, the algae at the bottom of the marine food chain, need to grow.
Phytoplankton produces more than half of the world’s oxygen and sucks as much carbon dioxide out of the atmosphere as four Amazon rainforests. More whales equals more phytoplankton — and therefore more carbon removal. According to Connel Fullenkamp, an economics professor at Duke University in North Carolina, that equation renders great whales, or rather their carbon capture and sequestration services, a potentially valuable and tradeable asset.
