Because whales, with their tremendous appetites and equally impressive plumes of excrement, literally fertilize the Earth, bringing nutrients like phosphorus up from the ocean’s depths and transporting these critical resources across the world.
According to a study published this week in the Proceedings of the National Academies of Sciences, the loss of Earth’s largest poop machines, as well as certain smaller fish and seabirds, has had a profound impact on global nutrient cycles, potentially weakening ecosystem health, fisheries and agriculture. Let’s explore how it works." @ GIZMODO:
