Trawling, a fishing practice that involves dragging a large net across the seafloor, may be inadvertently unleashing much more carbon dioxide into the atmosphere than previously thought, according to a new study.
The study, published Wednesday in the journal Nature, found that trawling can disturb the seafloor to a far greater extent than previously realized, leading to the release of large amounts of carbon dioxide that have been stored in the ocean floor for centuries.
The authors of the study say their findings suggest that trawling may be a far greater source of greenhouse gas emissions than has been previously estimated.
Trawling is a common fishing practice around the world, and is used to catch a wide variety of marine species, including shrimp, cod, and flounder.
The new study found that trawling can disturb the seafloor to a far greater extent than previously realized, leading to the release of large amounts of carbon dioxide that have been stored in the ocean floor for centuries.
The study was conducted by researchers from the University of Exeter in the United Kingdom and the University of California, Santa Barbara.
The authors of the study say their findings suggest that trawling may be a far greater source of greenhouse gas emissions than has been previously estimated.
They say that the emissions from trawling could be equivalent to up to 10 percent of all global greenhouse gas emissions from human activities.
The study’s lead author, Dr. Andrew Thurber of the University of Exeter, said in a statement that the findings show that trawling “should be considered alongside other human activities that are changing the environment.”
“Trawling is a widespread fishing practice, so it is important to understand the extent of its environmental impacts,” Thurber said.
The authors of the study say that their findings suggest that trawling should be better regulated in order to minimize its greenhouse gas emissions.

Does trawling release carbon?
Trawling is a type of fishing gear that is dragged along the sea floor to catch fish. It can cause extensive damage to the seabed, which can release large amounts of carbon dioxide (CO2) into the water.
CO2 is a greenhouse gas that contributes to climate change. It is important to reduce the amount of CO2 that is released into the atmosphere, as it is causing global temperatures to rise.
The damage that trawling causes to the seabed can release large amounts of CO2 into the water. This CO2 then enters the atmosphere, where it contributes to climate change.
In order to reduce the amount of CO2 that is released into the atmosphere, we need to reduce the amount of trawling that takes place. Trawling can be replaced with more sustainable fishing methods, such as jigging or seine netting.
We also need to find ways to reduce the amount of CO2 that is released from the seabed. This can be done by restoring damaged seabed habitats, and by using more environmentally friendly fishing gear.

How does trawling harm the climate?
How does trawling harm the climate?
Trawling is a fishing technique where a large net is dragged along the sea floor, scooping up everything in its path. This can include fish, crustaceans, turtles, dolphins, and seabirds.
The process of trawling can be very damaging to the environment. Trawling can damage coral reefs and seagrass beds, which can affect the marine ecosystem. Trawling can also release large amounts of carbon dioxide and methane into the atmosphere, which can contribute to climate change.
In addition to its environmental impacts, trawling can also be harmful to the climate because it can reduce the populations of fish, crustaceans, and other marine creatures. This can in turn impact the food chain, and can lead to a decline in the populations of marine predators.
Trawling is a relatively inefficient way to catch fish, and it can often result in the capture of unwanted animals, such as dolphins and seabirds. It is therefore important to consider the environmental and climate impacts of trawling before using this fishing technique.
How does trawling affect marine life?
Trawling is a form of fishing that involves dragging a large net along the sea floor. This can cause significant damage to marine life, ecosystem and habitats.
Trawling can damage the seabed, which can lead to the erosion of the coastline. This is because the net can drag along the sea floor, uprooting and destroying plants, animals and other objects. This can also damage the habitat of marine animals, which can disrupt their natural feeding and breeding patterns.
Trawling can also kill marine life. This is because the net can trap and kill animals, including dolphins, whales, seals and turtles. It can also damage their habitats, which can lead to a decline in their population.
Trawling can also affect the quality of the water. This is because it can release pollutants, such as oil and heavy metals, into the sea. This can contaminate the water and make it unsafe for marine life.
In conclusion, trawling can have a significant negative impact on marine life. It can damage the seabed, kill marine life, and contaminate the water. As a result, it is important to minimise the impact of trawling on the marine environment.
Is bottom trawling bad for the environment?
Bottom trawling is a fishing technique that involves dragging a fishing net along the sea floor. This can damage the sea floor and the creatures that live there.
Bottom trawling can cause extensive damage to the sea floor. The net can disturb or destroy the sea floor, and can also damage coral reefs and other marine life. This can have a negative impact on the local marine ecosystem.
Bottom trawling can also have a negative impact on fish populations. The net can catch and kill fish and other marine life, and can also damage their habitat. This can reduce the fish population and disrupt the marine ecosystem.
Bottom trawling is a potentially harmful fishing technique, and it is important to consider the environmental impacts of this technique.
Does fishing release carbon dioxide?
When most people think of carbon dioxide emissions, they think of cars and power plants. But what about fishing?
A new study has found that, contrary to popular belief, fishing can actually release large amounts of carbon dioxide into the atmosphere. The study, published in the journal Nature Climate Change, found that global fishing activities release about 1.5 billion metric tons of carbon dioxide every year.
That’s the equivalent of the emissions from more than 300 million cars.
The study also found that, while fishing may not be a major source of carbon dioxide emissions, it is a significant source of emissions in some parts of the world. In fact, fishing is the second-biggest source of emissions in the Pacific region, after agriculture.
So why does fishing release carbon dioxide?
The main reason is that, when fish are caught and killed, they release carbon dioxide that was stored in their bodies. This carbon dioxide comes from the food that the fish ate, and from the water that they swam in.
In addition, when fishing boats motors run, they produce emissions that include carbon dioxide.
So what can be done to reduce fishing’s carbon dioxide emissions?
One solution is to create more fish sanctuaries, where fishing is not allowed. This would help to reduce the amount of carbon dioxide that is released into the atmosphere.
Another solution is to improve the fuel efficiency of fishing boats. This can be done by using more energy-efficient motors, and by reducing the amount of time that boats spend travelling to and from fishing grounds.
Ultimately, reducing fishing’s carbon dioxide emissions will require a combination of measures, including better management of fisheries, and changes in consumer behaviour.
So does fishing release carbon dioxide?
The answer is yes, but there are things that can be done to reduce the emissions.
Does fishing produce CO2?
CO2 emissions from fishing are a major contributor to global climate change.
A recent study by Oceans Deeply found that the annual emissions from fishing vessels are equivalent to the annual emissions from about 9.5 million cars. This makes the fishing industry one of the world’s largest emitters of CO2.
The main source of emissions from fishing vessels comes from the burning of diesel fuel. Other sources of emissions include the use of refrigerants and the release of CO2 from the catch itself.
Many people are unaware of the significant greenhouse gas emissions from fishing. And even those who are aware often assume that the emissions are negligible in comparison to other sources of emissions.
But the truth is that the emissions from fishing are a major contributor to global climate change. In fact, they may be responsible for as much as 15% of all human-caused emissions.
This is a problem that we need to address if we are to have any hope of averting catastrophic climate change. The fishing industry must reduce its emissions if we are to keep global temperature rise below 2 degrees Celsius.
Fortunately, there are ways we can reduce emissions from fishing. One of the simplest is to switch to more fuel-efficient vessels. Another is to use cleaner fuels, such as liquefied natural gas.
We also need to reduce the amount of fish we catch. The United Nations Food and Agriculture Organization has warned that if we don’t make this change, we could see global stocks of fish decline by as much as 60% by 2048.
So, what can we do to reduce the emissions from fishing? We need to use more fuel-efficient vessels, use cleaner fuels, and reduce the amount of fish we catch.
How much do trawlers destroy every year?
Every year, trawlers cause significant damage to the marine ecosystem. Trawling is a type of fishing that involves dragging a weighted net along the ocean floor. This can indiscriminately damage or kill marine life that is caught in the net.
In addition to the damage caused by the nets themselves, trawlers also produce large amounts of bycatch. Bycatch is the term used for the marine life that is caught in fishing nets but is not the target species. This can include endangered and protected species, as well as juvenile fish and other marine life that is essential for the health of the ecosystem.
Trawling can also cause damage to the ocean floor. The nets can flatten coral reefs and other delicate habitats, and can also damage the seabed by stirring up sediment. This can smother marine life and disrupt the food chain.
It is estimated that trawlers destroy around 10% of the world’s marine ecosystems every year. This amounts to millions of animals being killed or injured, and billions of dollars of damage being done. Trawling is a very destructive fishing method, and it is important to find ways to reduce its impact on the marine environment.
