Over the last couple of decades the farmed salmon industry has convinced people that salmon is an important perhaps necessary source of protein and omega-3 fatty acids.
According to the Mayo Clinic: “Most nuts appear to be generally healthy, though some may have more heart-healthy nutrients than others. For example, walnuts contain high amounts of omega-3 fatty acids. Almonds, macadamia nuts, hazelnuts and pecans also appear to be quite heart healthy.”
And in “What If We’re Thinking About Agriculture All Wrong?, Elspeth Hay writes “Nuts store well — acorns, for instance, can keep for over a decade. And for eaters, nuts are what nutritionists call “nutrient-dense” — they have high vitamin and mineral content relative to their weight. They offer a balanced ratio of carbohydrates, proteins, and fats. And perhaps most importantly for human tastes, they can be made into oils and flours.”
Elspeth also points out that trees “grow year after year, sequester carbon, build soil, and offer resilience in the face of erratic weather.”
Compare nut trees to either net pen or land based salmon farming and it’s clear; truly sustainable good nutrition is possible without the real issues of animal welfare and important local enviromental issues such as sea lice or heavy carbon footprint.
Also, sea vegetables and shellfish aquaculture already offer important alternatives to finfish such as salmon.
