A 2021 paper estimated that bottom trawling contributed between 600 and 1500 million tons of carbon dioxide a year by disturbing carbon dioxide in the sea floor – emissions approximately equivalent to those of Germany, or the aviation industry. [3] [4] [5] However, these values are highly uncertain and have been criticized as overestimates.
After various unsuccessful dives and spotting signs of bottom trawling on the seafloor, they feared that it might have been destroyed altogether. ... which absorb carbon dioxide from exhalations ...
Furthermore, the ocean's function as a carbon dioxide sink, alterations in the atmosphere, ultraviolet light, ocean acidification, viral infections, the repercussions of dust storms transporting agents to distant reefs, pollutants, and algal blooms represent some of the factors exerting influence on coral reefs.
Overfishing and pollution of the oceans also affect their carbon storage ability and thus contribute to the climate crisis. [26] [27] [28] Carbon stored in seafloor sediments risk release by bottom-trawling fishing. [29] [30]
Most is carbon dioxide from burning fossil fuels: coal, oil, and natural gas. Human-caused emissions have increased atmospheric carbon dioxide by about 50% over pre-industrial levels. Emissions in the 2010s averaged a record 56 billion tons (Gt) a year. [17] In 2016, energy for electricity, heat and transport was responsible for 73.2% of GHG ...

Bottom trawling also poses a detrimental effects to the sea and using marine geology techniques can be helpful at mitigating them. [65] Bottom trawling, generally a commercial fishing technique, involves dragging a large net that herds and captures a target species, such as fish or crabs. [ 66 ]
Trawling can be divided into bottom trawling and midwater trawling, depending on how high the trawl (net) is in the water column. Bottom trawling is towing the trawl along (benthic trawling) or close to (demersal trawling) the sea floor. Bottom trawling is an industrial fishing method in which a large net with heavy weights is dragged across ...
