Did Mother Nature anticipate that we would mess up her world so badly? She, as James Lovelock writes in [*Gaia*](http://books.google.com/books?id=89GBVioWGUgC&printsec=frontcover&dq=lovelock+gaia&source=bl&ots=Ih98f3MeHi&sig=uBpcBAaBX2n7C4yOApup1Aaqpa0&hl=en&ei=wZ0aTJjSDYX7lwe6_83XCg&sa=X&oi=book_result&ct=result&resnum=7&ved=0CDYQ6AEwBg#v=onepage&q&f=false), created a system that can maintain a nourishing environment for all her species. Now we are told by scientists that one of the more intelligent creatures around (maybe more so than we) can contribute to our battle against global climate change. Is it self (whale) preservation or concern for a fellow species?
Here’s the article. The headline tells the story: “Scientists Discover Sperm Whale Poop Fights Global Warming.” The secret is that these whales’ feces contain large amounts of iron which act to fertilize algal growths which capture carbon dioxide. Great engineering feat!
