Summary

Story summary

Bottom trawling disrupts seafloor sediments, potentially releasing 55-60% of resuspended carbon, comparable to emissions from Italy or Spain.
Expanding trawling in warming Arctic regions raises concerns about methane release from shallow deposits.
The method causes significant ecological damage, including habitat destruction and increased greenhouse gas emissions.
