Is this the most valuable thing in the ocean? - David Biello
Let’s Begin…
Whales frequently surface to take in air and let out massive plumes of waste. And while this slurry might seem disgusting, whale poop is much more desirable than it may seem. In fact, it may be one of the most important substances in the ocean — and the world. So, what makes whale poop so vital to our ecosystems? David Biello shares the surprising benefits of whale excrement.

When we think about the ocean's complex ecosystems, we rarely consider the role of whale poop. Yet, this seemingly insignificant substance is a cornerstone of marine life and a key player in combating climate change. Whale poop, rich in nutrients, particularly iron, plays a vital role in sustaining phytoplankton populations, which are essential to the health of the ocean and our planet.
The Secret Ingredient: How Whale Poop Nourishes the Ocean
Whale poop might not sound glamorous, but it’s a critical element in the marine food web. Whales consume massive amounts of krill and other small marine creatures, and when they defecate, they release a slurry of nutrients, including iron, back into the ocean. These nutrients are crucial for the growth of phytoplankton, microscopic plants that form the foundation of the marine food chain. A single whale's waste can fuel entire phytoplankton blooms, which are visible from space.
Phytoplankton: The Tiny Titans of Climate Regulation
Phytoplankton do more than feed marine animals—they also play a crucial role in regulating the Earth's climate. These tiny organisms produce up to 50% of the oxygen we breathe. More importantly, they absorb vast amounts of carbon dioxide from the atmosphere. Without whale poop to nourish these vital organisms, our planet would struggle to maintain the delicate balance of carbon in the atmosphere.
Whale Populations and the Climate Crisis: A Direct Connection
The decline in whale populations due to centuries of industrial whaling has disrupted this nutrient cycle. With fewer whales in the ocean, there is less whale poop to sustain phytoplankton populations. This reduction affects marine biodiversity and hampers the ocean's ability to capture carbon. Restoring whale populations is not just about conservation—it's a critical strategy for mitigating climate change.
How We Can Help: Protecting and Replenishing Whale Populations
- Enforcing Whaling Moratoriums: International agreements like the International Whaling Commission's moratorium on commercial whaling have been instrumental in allowing whale populations to recover. Continued enforcement and expansion of these protections are vital.- Safer Fishing and Shipping Practices: Whales often fall victim to ship strikes and fishing gear entanglements. Implementing whale-safe fishing methods and rerouting shipping lanes can significantly reduce these threats.- Reducing Ocean Pollution: Pollution, particularly plastic waste, significantly threatens whales and their habitats. Efforts to clean up the oceans and reduce plastic use are essential for whale conservation.
Leading the Charge: Organizations Making a Difference
Several organizations are at the forefront of protecting whale populations and, by extension, the health of our oceans:
- The International Whaling Commission (IWC): The IWC plays a crucial role in regulating whaling and has been instrumental in enforcing the global moratorium on commercial whaling.Oceana: A non-profit organization focused on ocean conservation, Oceana campaigns for protecting marine wildlife, including whales, through advocacy, research, and policy change.Sea Shepherd Conservation Society: Known for its direct-action approach, Sea Shepherd actively works to prevent illegal whaling and other activities threatening marine life.
