You know that back in the 18th to early 19th century, soap was made out of Whale blubber fat?
One of the reasons and antagonists that almost led to the extinction of supra-echelon species of whales: the blue whale, humback whale, the sperm whale (the book Moby Dick illustrates the man vs nature correlation and importance whaling for 'soap, candles' had on the social fabric of Western society)
Thank the Lord for the inception of biochemical substitution, now we can just chemically create 'whale blubber-like proteins' that are essential for the creation of soap.
