Your study provides a compelling vision for sustainably increasing food production from the sea. However, considering the ambitious scenarios for mariculture expansion, especially under the ‘technological innovation (ambitious)’ scenario, how do you address the potential ecological trade-offs of sourcing alternative feed ingredients such as terrestrial plant proteins, insects, or genetically modified crops? Could these innovations shift environmental pressures from marine ecosystems to terrestrial ones, thereby undermining sustainability goals on a broader scale? Additionally, have you considered the economic and social feasibility of such transitions in regions with limited technological and financial resources?
