I thought it brought up a lot of items that people may over look.
Yep, I found this tidbit from that article quite interesting....
"Unabated algal blooms in lakes and stagnant waters usually leads to massive decrease
in oxygen content especially in the lower lake regions which often leads to sudden episodes of fish killings in affected water sheds.
- in 2008, there were 146 known coastal regions in the world in which fish and bottom-
feeding life forms have been entirely eliminated due to algal bloom connected oxygen
removal from these waters;
- one of these so-called
"dead zones" is in the Gulf of Mexico which is about the size
of the city of New Jersey and expanding;
Only heavy investment into modern waste water treatment plants in the 1960s through 1980s in the U.S., Europe and other parts of the world - with the successful removal of phosphates and nitrogen from human waste streams - saved many prominent lakes (e.g. Lake Washington in the U.S., Lake Konstanz & Tegernsee in Germany) from progressive oversedimentation and "biological overkill"."
Algae CAN be both your FRIEND AND ENEMY.... A type of love / hate relationship.
