And therein lies our disagreement. You say phytoplankton decrease is due to soil conservation efforts and my scientists say it is due to ocean acidification from CO2. I'll trust the scientific consensus over your opinion, but you are welcome to your opinion.

The likely cause of the problem is the LACK of nutrients, probably due to man's EXTENSIVE GLOBAL SOIL CONSERVATION efforts which has to led to tremendous increases in crop yields. Before we started plowing up the Great Plains 150 years ago soil erosion was actually very low in this country. Most erosion happens along river banks. That has decreased over the years, especially on the Mississippi river do to "armoring" and dyking of river banks. Also damming rivers decreases silt flow to oceans. Active farming actually increases total soil erosion.
