这里的粮仓不是指传统意义上的粮食———大米、小麦和玉米，而是指其他更广泛的能提供人类营养需要的食物。譬如，一些海洋学家指出：仅位于近海水域自然生长的海藻，年产量已相当于目前世界年产小麦总产量的１５倍以上。如果把这些藻类加工成食品，就能为人们提供充足的蛋白 The granary here does not refer to traditional foodstuffs such as rice, wheat and corn but refers to a wider range of other foods that provide human nutrition needs. For example, some oceanographers point out that algae, which grow naturally only in the offshore waters, have an annual output equivalent to more than 15 times the annual output of wheat in the world. If these algae processed into food, can provide people with enough protein
