Climate change poses a significant risk to the availability of essential nutrients from seafood, with potential declines of up to 30% by the century's end, especially impacting low-income countries. UBC research, published in 'Nature Climate Change,' underscores that high carbon emissions and low mitigation efforts could exacerbate nutrient deficits, while adherence to the Paris Agreement targets may lessen the declines. The study analyzes historical data and future projections of nutrients like calcium, iron, protein, and omega-3 fatty acids, highlighting a stagnation in nutrient availability since the 1990s despite mariculture gains.
