discovery.com brings us this:
Whale waste is rich in iron so it stimulates the growth of phytoplankton, which then serve as carbon traps that remove some 400,000 estimated tons of carbon from the atmosphere each year.
Since carbon has been linked to greenhouse gases, sperm whales likely reduce global warming.
Sperm whale waste isn't much to look at -- a diarrhea-like substance with a few squid beaks floating around -- but new research has found it removes carbon from the atmosphere, helping to offset greenhouse gases that have been tied to global warming.
There you go! That diarrhea-like substance with squid beaks ... it helps the environment. So leave it there! Don't try to bring it home.
