Whales help feed the ocean from the bottom up. They dive deep to eat, then return to sunlit surface waters to breathe and release iron-rich waste. That iron is the exact nutrient that tiny floating plants called phytoplankton need to bloom.

More phytoplankton means more oxygen, more carbon pulled out of the air, and more food at the base of the marine food chain. Industrial whaling did not just shrink whale numbers. It weakened a nutrient cycle that had kept oceans productive for millions of years.
