Agriculture is the primary source of greenhouse gas (GHG) emissions, accounting for around one-third of overall GHG emissions. It contributes much more to climate change than global power or heat generation. GHGs released into the atmosphere trap heat, causing global temperatures to rise. In 2014, the journal Climatic Change released extensive research on GHG emissions from food. The results align with expectations: eating more meat raises carbon dioxide emissions.
However, severe vegans and persons who solely consume fish have nearly identical emission profiles, with a 1% variation. The sort of food we eat significantly impacts how much space we can protect from agricultural activity. Seafood has a minor impact on freshwater and the environment than land-based diets. Land-based meat, particularly ruminant meat, contributes significantly to deforestation. LCAs (life-cycle assessments) are a scientifically validated method of measuring the environmental impact of foods.
According to the study, wild-caught fishing has the most harmful environmental influence. Farmed shellfish is maybe the least environmentally damaging food on the earth. Seafood 101 delves into the numerous components of fisheries management and the science that influences each seafood species’ long-term viability. If you like beef, you can do more for the environment than if you do not like beef.
