To dig deeper into the relations of One Health, the following strategies show some problems and what is already done (in the EU) to minimise the environmental impact.

Another leading question is:

The demand for aquatic products is rising due to population growth, health-focused diets, and their low carbon footprint. However, this increase adds pressure to already strained natural ecosystems and scarce resources, highlighting the need for sustainable management.

Aquaculture in the EU
The sustainability and regulation of aquatic production are shaped by a robust framework of policies, agreements, and collaborative efforts at various levels. Key policies such as the Common Fisheries Policy (CFP) and the Marine Strategy Framework Directive (MSFD) set the foundation for responsible resource management and environmental protection in European waters. Further, the European Green Deal, notably through its Farm to Fork Strategy, promotes sustainability across the entire food system. International agreements, strategic roadmaps, and partnerships—both national and international—play a crucial role in aligning objectives and coordinating effective action. Together, these mechanisms ensure that aquatic resource use is carefully regulated, continuously improved, and guided towards greater sustainability.

MSFD - Ecosystem-based management (EBM)
A holistic approach to aquaculture management considers the entire ecosystem, including human communities, to ensure balanced and sustainable production. The goal is to maintain the surrounding environment in a healthy, non-toxic, productive, and resilient condition, thereby supporting both the needs of aquaculture and the long-term well-being of the ecosystem.

“The ecosystem-based approach to the management of human activities is central to the MSFD (Marine Strategy Framework Directive) and ensures that ‘the collective pressure of such activities is kept within levels compatible with the achievement of good environmental status and that the capacity of marine ecosystems to respond to human-induced changes is not compromised, while enabling the sustainable use of marine goods and services by present and future generations” (EC, 2020a).

Actions of the Farm to Fork Plan (within the Green Deal)
To ensure effective control and compliance with EU standards — covering hygiene, contamination, animal welfare, plant health, the use of pesticides, and antibiotics — the European Union operates a robust system that applies to both domestically produced and imported goods from non-EU countries. This system includes regular inspections, traceability requirements, and strict controls at all stages of the supply chain to maintain food safety and animal and plant health. Additionally, the EU manages international relations in areas such as food safety, animal health, and nutrition, working closely with both national authorities and partner countries. Collaboration with the European Food Safety Authority (EFSA) is vital, ensuring that risk management decisions are grounded in the latest scientific knowledge across a variety of topics.
