The ocean is a vast natural sponge for carbon dioxide. Approximately 30% of the world’s annual carbon emissions. However, certain human activities make the sponge less absorbable, as explained in new research. Research shows that bottom trolls of fish like bottom and crustaceans trolls fish like bottom and crustaceans, and fish bottom trolls to maintain harbors and harbors cause cascades of chemical changes that disrupt the seabed, disrupt the seabed with drought to maintain harbors and reduce the ocean’s ability to suck carbon to warm the climate from the atmosphere, research suggests Released on March 28th In the journal Advances in science.
Each year, we combine the effects of dr and troll release between 2-8 teragrams (2-8 million metric tons) of carbon dioxide, which corresponds to annual energy. Emissions from up to 1 million US homesaccording to the new analysis. Compared to all carbon emissions resulting from burning fossil fuels worldwide (or in a single industrialized nation) Annual emissions), the amount of co2 Certainly, it’s small.
“First and foremost, we need to reduce our emissions. There’s no way to avoid that.” Sebastiaan van de Veldesays the lead research author and marine geochemists at the University of Otago in New Zealand Popular science. But as governments and business investors pour huge amounts of money and resources into Moonshot’s carbon capture projects, the findings of the seabed are important, says Van de Velde.
By shifting the way and where trolls are performed, all greenhouse gas emissions can be reduced by hundreds of times. Currently, operational direct air carbon capture plants on Earthhe points out. Reducing trolls and dr in a climate-conscious way can bring about carbon benefits comparable to majors Mangrove and wetland restoration projectsonly a small portion of the cost, he explains. That’s not to say that we should stop rehabilitating coastal ecosystems, which offer many benefits, such as minimizing erosion and increasing storm resilience. But perhaps that means we need to consider changing the way we fish.
There is a previous research The troll was foundand other seabed turmoil, Releases greenhouse gases. However, this previous study focuses on organic carbon. Essentially, the decaying mud at the bottom of the ocean traps the carbon sliver in the limbo. The troll can return the mud to the surface, where the carbon stored there can be circulated through the microbial food web and re-released into the air as CO.2.
A new study examines the acidity of inorganic carbon and oceans, opposite sides of the coin. Important chemical reactions involving dissolved rock particles and minerals unfold at the seabed. These reactions help to turn the marine environment into more alkaline (i.e. basic). The formation of alkalinity is a central feature of the marine carbon cycle. That’s why the ocean can absorb carbon dioxide from the air in the first place.2 It dissolves in water and turns into carbonated acid. If things become too acidic and the oceans are saturated, they cannot be absorbed any more. The alkaline subsea processes counter acidification, prime the oceans and intake additional carbon dioxide.
Pull heavy nets or chains across the seabed to catch fish, or scoop up dr bone deposits and beat standard chemical cycles. Both activities introduce more oxygen to the ocean bottom than is normally present. Oxygen reverses the reaction that produces alkaline molecules, and instead creates acidity, impeding the seawater’s ability to absorb CO2 From the atmosphere.
To estimate the full impact of ed and trolls around the world, Van de Velde and his colleagues relied on actual data cataloguing submarine carbon flux, oxygen levels, and PH. They constructed a global mathematical model of subsea alkalinity and used separate statistics for dr and trolls to speculate how much these activities would disrupt acid-base chemistry. They determined that the muddy reach of coastal shelves is the most important type of seabed surface for producing alkalinity and is therefore affected by dr dr and trolls.
The ultimate value they came (again, 2-8 teragrams of carbon dioxide produced per year) involves some uncertainty as the data on dr dr and trolls is limited, so the seabed is not uniform and depends on the type and location of equipment used by the fishing boat or dredger.
“They are the best numbers we can get, but not necessarily [100 percent] The correct numbers,” says Van de Verde. Popular science. “There’s a lot of things we do. There’s something we really don’t know about the impact. There’s a lot of unknown unknown in the ocean. I don’t even know what I don’t know.” He hopes that his research represents the beginning of a better understanding, leading to more accurate future analysis.
In the meantime, he also hopes that this initial attempt to quantify the inorganic carbon effects of trolls and dr will spur coordination of marine industries and regulatory agencies. Advances in equipment can lead trolls and reduce fuel efficiency without negating the supply of seafood. Also, in some areas, trolls may be limited to 40% of current fishing grounds or even less than 60%, with yields dropping by only 10%.

“To me, that seems easy,” says Van de Verde. Theoretically, it is possible to eat fish (which has a much less impact on the climate), but the industry must be willing to be swept away by the trend of change.
