Abstract:
The paper emphasizes the aggravated international situation caused by the accelerated global warming of the atmosphere, concurrent with the less effective governmental response to limiting the greenhouse gas emissions. There is no objective assessment of the real danger and extreme action on all sides against the approaching global catastrophe predicted by a group of scientist to begin in 2021. The traditional engineering methods for direct absorption of the CO2 from the atmosphere are considered prohibitively expensive and largely inapplicable. The proposed method is to extract the CO2 from the atmosphere and sea water by using ecological hydro-technical structures (EHS) for mariculture (marine aquaculture). Under normal conditions, they are overgrown by mussels using the unlimited amounts of Ca and CO2 in seawater to build their shells. Washed ashore by the waves, the shells accumulate into shelly-sandy beaches thus preventing the coastal erosion and the landslides. The EHS solve practically at no cost and simultaneously all the protection and exploitation problems of the coastal zone and shelf, including the absorption of the CO2 acting as “biological pumps”, as the funds are spent only for building and installation of the structures.
