Eating fish may make the ดาวน์โหลดสล็อต xo climate worse than previously thought, according to a recent scientific study.Previous research has indicated that seafood has less carbon footprint than other animal proteins because fishing does not require farmland or livestock supervision.But a new study claims that fishing using heavy nets dragging across the seabed, known as bottom-hauling, emits about the same amount of carbon dioxide (CO2) worldwide in the aviation industry.The seabed sediment that acts as a large carbon bath is turbulent during this type of trawling and results in the CO2 being released.The ocean is full of tiny organisms we call plankton, microscopic algae and tiny shrimp, for example, said Dr. Sala, National Geographic resident explorer and lead study published in Nature.

Speaking to the BBC World Service's The Climate Question, he said: "Most of these creatures, when they die, will sink to the bottom of the ocean, and over billions of years, those tiny creatures will accumulate. Clone firstHis paper calculated that, on average, about 1Gt (gigaton) of carbon dioxide was generated due to the bottom trawling activity. "That's about 2% of global CO2 emissionsBy comparison, it is estimated that aviation emissions approximately 1.04Gt, or 2.5% of global emissions each year.Lower trawling is one of the most common fishing methods in the world and the government says it accounts for half of the UK's annual fishing.
However, the climate question was discussed with fishing experts

who disputed the findings and were concerned that Dr Sala had overestimated the CO2 emissions caused by bottom trawling.The South African Deep Sea Trawler Industry Association said it was not yet known how much carbon in the ocean entered the atmosphere.Dr. Sala believes this information is not as important as it should be. His argument is that if too much CO2 is absorbed into the water from the seabed, the ocean will absorb less carbon from the air.The oceans absorb a quarter or more than a third of carbon dioxide emissions every year, so if we add more CO2 in the water, it reduces the ability of that part of the ocean to absorb more carbon dioxide from the atmosphere." He said


Protect the ocean

Protecting parts of the ocean could be one way to stop these emissions, he argues, and many countries have created Marine Protected Areas, or MPAs.Almost a quarter of Britain's waters are covered by MPAs, however, the Oceana campaign group said most of the area still allows bottom trawling.Minna Epps, global director of the International Union for Conservation of Nature (IUCN) Maritime and Polar Programs, said it was because some MPAs allowed these kinds of activities to take place.There are six different categories that the IUCN defines, fundamentally ranging from the absolute strict, no distraction, to the lowest category where you are allowed to have the lowest trawling activity within it.

The UK government said it was aware of "The critical role of marine habitats" and how the carbon stored in the seabed contributes to the fight against the climate crisis. It said it was committed to reducing the impact of the fishing industry on marine life.While trawling can cause carbon to be released from the sediment. But the process is complex and the overall impact is not clear, ”said a spokesman for the Department of Environment, Food and Rural Affairs (Defra).Defra said Britain wants to increase the number of MPAs and lead the claims. "For new global targets to protect at least 30% of the oceans by 2030"

But some in the fishing industry warn that too many marine protected areas are being set up as the bottom trawling could be moved elsewhere.Where the boats have been moved are affected, not just that, likely there will be anglers there, what are the consequences there," said Barrie Deas, chief executive of the National Fishers' Union.Like all citizens of the world, we as an industry take climate change very seriously and we have to be involved in solving this problem,We, as planets, must be able to forage, and the bottom trawling has a very important role to play.
I must say, I thought this was a pretty interesting read when it comes to this topic. Liked the material. . . . . Isoleren muur
