You might not think of a sea creature as helpful in the prevention of climate change, but sperm whales have been doing their part to cool the planet by doing what most animals do best: pooping.

    At first, I thought you were going to say the carbon in whale poop sank and was sequestered in the deep ocean and was surprised when you said they add limiting nutrients to the surface phytoplankton to increase growth. Many geoengineering advocates support fertilizing the ocean especially with iron which is a limiting nutrient. To think the whales were doing this for free! I always loved seeing pods of up to two dozen Humpback whales at a time while kayaking the inside passage in B.C. and AK.

    "Just imagine..." It seems like a million sperm whales should help to sequester 20,000,000 tons per year. (240000/12000 = 20 per whale). That said, it's not clear that whales outside the Southern Ocean are *as useful* given what was said earlier in the video.

      I was thinking this too. If most of the iron is literally just from dust dissolving, lets just dump some more iron II dust in the parts of the ocean that need it

  56. Archibald Mirenopteryx

    Essentially, what you described is a mineral cycle, where the whales bring up the iron from deep waters and expel it as poop in the shallow waters - where there's light. And poop in general is a VERY nutrient rich substance. It may stink, but the things that make it stink are used by a LOT of plants, microbes, and even other animals. There's another mineral cycle that's quite famous: The phosphorous cycle. Phosphorous is common in the ocean but very rare on land, and it is a *vital* nutrient for plants. Phosphorus has only two ways to get to the land: By geological cycling of ocean bed to land masses, or by birds pooping. Yep. Seabird guano is one of the richest sources of phosphorous on Earth, and before we figured out how to make artificial phosphorous-containing fertilizer, guano deposits were more valuable than gold.

    1. Rampage
      19 ditë më parë

      it is important and it comes from animal products like meat fish eggs dairy etc... b12 helps your body produce red blood cells and without it you can get anemia. wich i belive means you don't have enough red blood cells to transport oxygen through your body. but i don't think it's somthing you should worry about if you eat regular animal products.

I don`t have the time or money to invest into this idea but I would like to share it with someone that perhaps could put it into practice. If anyone is in that position please send me a private message or respond here.
