The possibilities and challenges of kelp
This article by FoodPrint discusses the tension between the purported environmental benefits of kelp farming and consumers’ lack of familiarity with kelp as a food, and describes “regenerative” kelp farming systems that also produce oysters, clams and mussels. It sets out several ways in which kelp can be used, including in foods such as pesto or lasagne, as well as other uses such as bioplastics, fertiliser, biofuel and animal feed.
North America is the northern subcontinent of the Americas covering about 16.5% of the Earth's land area. This large continent has a range of climates spanning Greenland’s permanent ice sheet and the dry deserts of Arizona. Both Canada and the USA are major food producers and some of the largest food exporters in the world. Industrial farms are the norm in North America, with high yields relative to other regions and only 2% of the population involved in agriculture.
