“…In North America, there has been recent interest and industry growth for sugar kelp ( Saccharina latissima ) aquaculture 106 , 107 , though its production still represents less than 0.001% of global algae aquaculture 2 . Sugar kelp is a close relative of Japanese kelp ( Saccharina japonica ), the highest-cultivated algae species globally 2 , which has demonstrated contributions to food security in Asia 108 and the potential to sequester carbon 71 , 72 . Unlike Japanese kelp, however, sugar kelp is native to British Columbia waters 109 , making it an ideal species to consider for local aquaculture production.…”

Aquaculture has the potential to support a sustainable and equitable food system in line with the United Nations Sustainable Development Goals (SDG) on food security, climate change, and biodiversity (FCB). Biological diversity amongst aquaculture organisms can drive diverse contributions to such goals. Existing studies have assessed the performance of a limited number of taxa in the general context of improving aquaculture production, but few explicitly consider the biological attributes of farmed aquatic taxa at the FCB nexus. Through a systematic literature review, we identify key traits associated with FCB and evaluate the potential of aquaculture to contribute to FCB goals using a fuzzy logic model. The majority of identified traits are associated with food security, and two-thirds of traits linked with food security are also associated with climate change or biodiversity, revealing potential co-benefits of optimizing a single trait. Correlations between FCB indices further suggest that challenges and opportunities in aquaculture are intertwined across FCB goals, but low mean FCB scores suggest that the focus of aquaculture research and development on food production is insufficient to address food security, much less climate or biodiversity issues. As expected, production-maximizing traits (absolute fecundity, the von Bertalanffy growth function coefficient K, macronutrient density, maximum size, and trophic level as a proxy for feed efficiency) highly influence a species’ FCB potential, but so do species preferences for environmental conditions (tolerance to phosphates, nitrates, and pH levels, as well as latitudinal and geographic ranges). Many highly farmed species that are typically associated with food security, especially finfish, score poorly for food, climate, and biodiversity potential. Algae and mollusc species tend to perform well across FCB indices, revealing the importance of non-fish species in achieving FCB goals and potential synergies in integrated multi-trophic aquaculture systems. Overall, this study provides decision-makers with a biologically informed assessment of desirable aquaculture traits and species while illuminating possible strategies to increase support for FCB goals. Our findings can be used as a foundation for studying the socio-economic opportunities and barriers for aquaculture transitions to develop equitable pathways toward FCB-positive aquaculture across nuanced regional contexts.

The environmental impact of drug manufacturing raises concerns about sustainability in healthcare. To address this, exploring alternative approaches to drug production is crucial. This review focuses on seaweed as a sustainable resource for greening drug manufacturing processes. Seaweed offers advantages such as renewability, abundance, and a positive environmental footprint. The review begins by providing an overview of sustainable drug manufacturing practices and the challenges faced in achieving sustainability. It then discusses seaweed as a sustainable resource, including cultivation techniques and environmental benefits. Seaweed has various applications in drug manufacturing, including extracting and purifying bioactive compounds with potential therapeutic properties. Seaweed’s role in developing green technologies, such as seaweed-based excipients, biodegradable packaging materials, and as a source of sustainable energy for drug manufacturing processes, is highlighted. The environmental and economic implications of incorporating seaweed-based solutions are discussed, emphasizing reduced carbon footprint and cost-effectiveness. Regulatory and industrial perspectives are addressed, examining challenges, and opportunities for implementing seaweed-based drug manufacturing. Collaboration between academia, industry, and regulatory bodies is crucial for successful integration. The review presents future directions and opportunities, including emerging trends and innovations in seaweed-based drug manufacturing, areas for further research, policy development, and industry engagement recommendations. Incorporating seaweed into drug production facilitates a reduction in environmental impact, promotes resource efficiency, and contributes to sustainable healthcare. This review showcases seaweed-based solutions as a means to foster a greener future for drug manufacturing, addressing environmental concerns, and promoting sustainability.
