The Sustainable-Seafood Case

Why it matters and isn’t overwhelming: the the-health-and-ocean (the seafood being healthy AND an ocean-sustainability question — the the-health-and-ocean; the the-both; the the-good-for-you-and-planet), the the-can-feel-overwhelming (the sustainability feeling-overwhelming — the the-overwhelming; the the-which-fish; the the-daunting), the the-doesnt-have-to-be (the choosing-well being doable-without-expertise — the the-doable; the the-not-hard; the the-simple-guidance), the the-your-choices-matter (the seafood-choices affecting-the-ocean — the the-choices-matter; the the-impact), the the-and-affect-quality (the sustainable-often overlapping-with quality-and-health — the the-quality; the the-overlaps), and the reframe (the sustainable-seafood as a doable, good-for-you-and-ocean choice — the choose-well; the the-not-overwhelming).

The How-to-Choose-Well Method

Choosing sustainable seafood simply: the the-use-guides-and-apps (the use seafood-guides/apps (they-do-the-work) — the the-guides; the the-apps; the the-let-them-help; the the-easy-tool), the the-look-for-certifications (the look-for sustainability-certifications — the the-certifications; the the-labels; the the-verified), the the-know-the-better-choices (the know a-few good-default-choices — the the-good-defaults; the the-better-choices; the the-go-to-fish), the the-smaller-fish-often-better (the smaller-fish (sardines, etc) often-sustainable-and-healthy — the the-smaller-fish; the the-sardines; the the-sustainable-and-low-mercury), the the-canned-and-frozen-count (the canned-and-frozen sustainable-options from the canned-fish chapter — the the-canned; the the-frozen; the the-accessible), the the-ask-your-fishmonger (the ask where-it’s-from — the the-ask; the the-source; the the-fishmonger), the the-variety-and-seasonal (the variety-and-local/seasonal — the the-variety; the the-seasonal; the the-mix-it-up), and the the-dont-need-perfection (the good-choices, not-perfection — the the-not-perfect; the the-better-is-good).

How it works

The Easy-Swaps-and-Resources Notes

Swaps and resources to shop smarter: the the-swap-to-better-options (the swap over-fished for sustainable-alternatives — the the-swaps; the the-alternatives; the the-trade-up), the the-canned-sustainable (the sustainable-canned-fish (sardines, salmon) from the canned-fish chapter — the the-canned; the the-sardines-and-salmon; the the-cheap-and-good), the the-seafood-apps-and-guides (the seafood-watch-style guides/apps — the the-apps; the the-guides; the the-resources), the the-cook-what-you-buy (the cook-it-well (confidence) from the cook-fish-with-confidence chapter — the the-cook-it; the the-confidence; the the-use-it), the the-shrimp-note (the shrimp-sustainability varies (check) from the shrimp-cooking chapter — the the-shrimp; the the-varies; the the-check), the the-budget-friendly-sustainable (the budget-friendly sustainable-options (canned, smaller-fish) — the the-budget; the the-affordable-sustainable), the the-progress-not-perfection (the every-better-choice counts — the the-progress; the the-counts), and the frame (sustainable seafood through the sustainable-seafood-case, the how-to-choose-well and easy-swaps-and-resources — the use-guides, better-defaults and smaller-fish that make good-for-you-and-ocean choices simple; the seafood, chosen-well). Eating more fish is great for your health, but the sustainability layer can feel overwhelming — it doesn’t have to be. Choose well simply: use seafood guides/apps (they do the work), look for certifications, know a few good-default choices, and lean on smaller fish (sardines — sustainable, healthy, low-mercury) and sustainable canned-and-frozen options. Ask your fishmonger where it’s from, favor variety, and aim for better choices over perfection: sustainable seafood, good for you and the ocean.
