The environmental impacts of consuming fish and eggs include overfishing, habitat destruction, pollution, and greenhouse gas emissions.

Overfishing
Habitat destruction
Pollution
Greenhouse gas emissions

These impacts raise important discussions about sustainability and dietary choices. Different perspectives exist regarding the consumption of fish and eggs, weighing ecological costs against nutritional benefits.

Overfishing: Overfishing occurs when fish are caught at a faster rate than they can reproduce. This practice leads to declining fish populations and threatens marine ecosystems. According to the Food and Agriculture Organization (FAO), approximately 34% of global fish stocks are overfished. For example, the Atlantic cod fishery was once one of the largest in the world, but it collapsed in the early 1990s due to overfishing. This overexploitation affects not only the fish species but also the marine food webs and local fishing communities.
Habitat destruction: Habitat destruction occurs when fishing practices, such as bottom trawling, damage ocean floors and coral reefs. These practices can severely disrupt marine habitats, reducing biodiversity. A study from the Pew Charitable Trusts in 2014 indicated that bottom trawling can destroy up to 50% of the seafloor habitat in some areas. Coastal habitats, like mangroves and wetlands, are also lost due to fish farming operations, which further impacts local wildlife and water quality.
Pollution: Pollution from fish farming and runoff from agricultural practices can contaminate waterways. Fish farming often leads to nutrient runoff, which can cause algal blooms that deplete oxygen in water and harm aquatic life. The World Wildlife Fund (WWF) states that up to 70% of marine pollution comes from land-based sources. Additionally, the use of antibiotics and chemicals in aquaculture can lead to water pollution, impacting surrounding ecosystems.
Greenhouse gas emissions: Greenhouse gas emissions from fish farming operations contribute to climate change. The aquaculture sector uses large amounts of energy to maintain production, transport feed, and process products, leading to a significant carbon footprint. According to research by FAO, the aquaculture industry accounted for 1.1% of global greenhouse gas emissions in 2020. Sustainable practices and alternative sources of food can help reduce this impact.
