April 15, 2025 — Humankind is inextricably dependent on the ocean. Many of our greatest civilizations have thrived on the rim of the ocean. Today, we are more reliant than ever on the ocean for our economic, social and physical well-being.
Maritime activities, from global trade to tourism, exceed US$3 trillion annually. The “ocean economy” is the fourth largest in the world. Furthermore, our global economic vitality is largely due to the cost-effective nature of ocean transportation, which contributes to the reduced price per ton of shipped goods.
From submarine cables to shipping, fisheries and aquaculture, we are increasingly reliant on the blue economy. Roughly 20 per cent of the animal protein that we eat comes from marine fish.
The ocean has changed dramatically in the past century, and we expect more change to come. Collapses of fisheries, coral reefs, shark populations and other species — along with increased dead zones, red tide blooms and invasive species — have followed increased human development, industrial use of the sea, climate change and pollution.
