The study, published in the journal Nature Climate Change, found that bottom trawling releases large amounts of carbon dioxide (CO2) from the seafloor, which is then released into the atmosphere. This CO2 contributes to global warming, which can lead to a range of negative impacts on the environment, including more extreme weather events, rising sea levels, and damage to coral reefs.
The study's findings are based on data collected from over 100 bottom trawling vessels operating in the North Sea. The researchers found that these vessels released an estimated 1.4 million tonnes of CO2 per year, which is equivalent to the annual emissions of about 300,000 cars.
The researchers say that their findings highlight the need for urgent action to reduce the climate impacts of bottom trawling. They recommend a number of measures that could be taken to achieve this, including:
* Reducing the amount of bottom trawling that is carried out
* Using more selective fishing gear that does not damage the seafloor
* Protecting areas of the seafloor that are particularly vulnerable to CO2 release
The researchers say that these measures would help to reduce the climate impacts of bottom trawling and protect the marine environment.
Bottom trawling is a destructive fishing practice that has a number of negative impacts on the marine environment. In addition to releasing CO2, bottom trawling can also damage coral reefs, seagrass beds, and other important marine habitats. It can also kill fish and other marine life, including endangered species.
