Erek Tinker wow, it sounds like a fascinating area of study!
Let's see: I believe it creates an awful lot of the oxygen we
breath... it's used as a thickener in milkeshakes and in other
food products... hmm... here in Florida we have problems with
Red Tide: Nitrogen that makes our plants grow GREAT *also* feeds
the red algae, causing it to grow in excess. (also phospherous
but that's been known ...for years, and the reason why it was
taken out of automatic dishwashing detergent, making it work
HORRIBLY now (just add a little TSP from the hardware store to
get the cleaning power back)...."
