Diatom Algae are phytoplankton that are responsible for about 25% of all photosynthesis on Earth. Gross Photosynthesis on Earth in terms of Carbon consumption is about 105 Billion Tons of Carbon consumed per year. Out of this about 46% is estimated to take place in water and 54% on land. Diatom Algae are estimated to account for about 23 Billion tons of Carbon consumption per year, i.e., about 50% of the Photosynthesis in water. Anthropogenic Carbon emissions are estimated at about 10 Billion Tons of Carbon per year. Therefore increasing the production of Diatoms by about 45% can result in consumption of all anthropogenic carbon emissions. In nature Diatom Algae are the best food for Zooplankton and Fish, therefore they are consumed and do not accumulate in waterways. So if Diatom production increases, fish production too will increase and all anthropogenic carbon emissions can be converted into fish biomass. This will help feed the growing population, reduce pressure on land based food production, restore biodiversity and fish and whales in Oceans, etc. Thus we can actually profit from consumption / removal of CO2 from atmosphere and oceans. Sewage contains nutrients, Nitrogen and Phosphorus, these are inputs for photosynthesis. Therefore sewage can be used to grow Diatoms, this is the best and most economical solution for sewage treatment and if the Diatoms can be consumed by Fish, we could actually profit from sewage treatment.
