Research has revealed the potential value of whale poo in mitigating climate change through its recycling of iron. Australian Antarctic scientists looking into ways to increase the amount of CO2-absorbing algae in oceans have traced the passage of iron through whale digestive systems and have found that whales take up iron when they consume shrimp-like krill.
Before commercial whaling began early last century, whales consumed about 190 million tonnes of krill per year, converting this into about 7600 tonnes of iron-rich faeces, which encouraged the growth of carbon-absorbing algae
