There are today about 812 to 2050 Million tons of Fish left in the Oceans compared to 7,000 to 15,000 million tons estimated only two century ago.

The remaining Fish stock produces 110 million Ton of Calcium carbonate Annually. Would we repopulate the Ocean with Fish to levels as two centuries ago. We would then increase the production of Calcium Carbonates by a factor of 10 to 14. Giving us an additional 1000 to 1400 million Ton of Calcium Carbonates. This additional Calcium Carbonate would raise the PH level of the Ocean, save the Coral Reefs and increase the CO2 absorption rate as well as help cool down the over all Oceanic Temperature and increase as well as accelerate the filtration of toxins and other polluted.
