Question

【题目】Zulema Munoz collects seaweed in a small coastal town 100 miles south of Santiago, Chile. A good week may see her cut 1,100 pounds of seaweed from the rocks where it grows.

Muftoz is one of the 30, 000 people for whom Chilean seaweed industry provides a livelihood. Throughout Latin America, the cultivation (种植) and collection of seaweed are gaining a support both as a source of food and as a means of ensuring food security in a region where 34 million people are food insecure and poverty affects 47 percent of the rural population. Countries such as Argentina, Brazil, Colombia, Cuba, Ecuador, Mexico, Peru, and Venezuela have all explored seaweed production for food. Yet as demand outpaces production and wild stocks have declined， more attention is being paid to sustainable cultivation and harvesting methods that can keep the industry surviving.

Seaweed has a long history in South American style of cooking. The native cooking of Chile made frequent use of cochayuyo, the most abundant of the country 750 types of seaweed. Today, cochayuyo is commonly found in place of meat incharquican, a traditional dish cooked slowly in a closed pan.

Kelp, a type of large brown seaweed, as the new vegetable is a global trend too, and for good reason. Nutritionally, seaweed is packed with iodine and other nutrients, and appears on trend-making menus in Google's New York cafeteria, though it used to be thought difficult to get people to eat it.

While 83 percent of cultivated sea vegetables are produced for human consumption, we aren’t just eating it. Seaweed is used in fertilizers and animal feed, and seaweed-based food additives are likely in many products in your kitchen and bathroom right now. Carrageenan, made from red seaweed, is in everything from shampoo and toothpaste to ice cream and some hot dogs.

While seaweed grows readily—there are concerns that humans are taking too much of the wild stuff. It is possible that overexploitation of natural seaweed resources could lead to significant ecological, economic, and social consequences at local, regional, and even global scales. In Latin American countries like Brazil and Peru, where the seaweed industry is based on harvesting wild seaweed rather than cultivated, the need for environmentally friendly models is urgent.
