If a weed is a plant whose virtues have not yet been discovered, then seaweed is ready for rebranding. This food source, underutilized in the Western world, is rich in vitamins and minerals such as iron and iodine. To cultivate, it requires no fresh water, no land, no chemical inputs, and no fertilizers, and it creates no nitrogen runoff. Furthermore, sea vegetables sequester carbon as they grow, helping to combat the effects of global warming and mitigate ocean acidification. When it comes to feeding a global population of 9.7 billion people in 2050, seaweed could play a large role in finding sustainable solutions.
Our oceans are straining under the extraordinary pressure of global demand. Humans eat seafood, and so do our livestock. Even our seafood eats seafood. It’s unsurprising then that ninety percent of our marine fisheries are fully fished or overfished. The repercussions of our insatiable hunger for seafood are both environmental and economic. The industry now loses more than $80 billion annually due to overfishing and decreasing fish stocks.
Creating sustainable alternatives is not only an environmental imperative but also a remarkable economic opportunity. The expansive, lumbering seafood industry is calling for mission-minded entrepreneurs, innovators, and investors to stem the tide of ecological destruction.
