Diatoms, Algae and the Environment: a tidbit
Diatoms are of great global importance. To start with, diatoms are responsible for between 20-40% of the earths oxygen production. This fact alone should make you want to hug a diatom. However, this huge contribution to global oxygen supplies is just a byproduct (even considered to be a waste product) of photosynthesis. The primary objective of any diatom is to fix carbon dioxide into energy and biomass. The resulting biomass happens to be tasty and nutritious to many organisms, and is therefore the base of many aquatic food chains, especially in marine systems. So, much of that tasty seafood we love, was once an unpretentious diatom.
Sometimes the high productivity of diatoms can get out of hand, especially in response to nutrient pollution into aquatic habitats. As this story reports, we are seeing an unprecedented bloom of the toxin producing diatom, Pseudo-Nitzschia all along the Pacific coast.
Our understanding of nature and the environment is incomplete, as stated by Stoermer and Smol in the above quote about potatoes and Cyclotella. And, the limited application of the knowledge we do have may be keeping us from making breakthroughs in areas of environmental remediation and environmental industrialism.
