This book presents a solutions based approach to reducing and removing CO2 from the atmosphere transforming it into solid (crystalline) CaCO3 through the ability of marine organisms such as molluscs, crustacea, corals, and coccolithophore algae. The overwhelming advantage of this approach is that it promises enhanced climate mitigation in comparison to planting forests, industrial/engineering carbon capture and storage process. It also provides a sustainable food resource. Furthermore, it would improve the ocean's biodiversity at the same time as the excess atmospheric CO2 released by our use of fossil fuels is returned to the place it belongs - as a present day fossil, safely out of the atmosphere to the distant future. If the level of finance and global effort that are readily foreseen for forest management and flue gas treatments were applied to expansion of global shellfish cultivation, curative amounts of carbon dioxide could be permanently removed from the atmosphere within afew decades. The concept presented in this book could have a profound influence on the life of the planet.

David Moores first degree was Hons Botany and Zoology, completing a PhD in Fungal Genetics and awarded DSc in Mycology (genetics, molecular biology, enzymology, developmental biology, mathematical modelling, evolution). David also has interests in space biology and planetary sciences. Published books include: 21st Century Guidebook to Fungi; Fungal Biology in the Origin and Emergence of Life; Fungal Conservation: Issues and Solutions; Fungal Morphogenesis; Biological and Medical Research in Space; Evolutionary Biology of the Fungi; Developmental Biology of Higher Fungi.

Matthias Heilweck has 30 years experience of business administration and management during his career as an independent industrial supplier. Oceanography has always been the focus of his spare time, despite living about 1000 km away from the coast. Matthias is now close to retirement and can devote more time to oceanography. In the best traditions of European amateur scientists, he is a non-academic freethinker who has developed ideas to help preserve the oceans as a healthy and sustainable food source for mankind.

Peter Petros is a research analyst and trained engineer working in mycological aspects of water and environmental engineering (fungi contribute to 10 out of the 17 UN SDGs). Presently working for Kääpä Biotech, a biotechnology company committed to healthier humans and ecosystems, which researches and develops novel industry solutions with fungi. His projects are aimed at ecological restoration, bioremediation and wastewater treatment. Skills are in Soil and Water engineering, Water Science, Civil Engineering, Biotechnology and Conceptual Analysis.
