A conservative projection shows the world's population growing by 32% (to 9.5 billion) by 2050 and 53% (to 11 billion) by 2100 compared with its current level of 7.2 billion. Because most arable land worldwide is already in use, and water and energy also are limiting, increased production of food will require a substantial increase in efficiency. In this article, we highlight the importance of animals to achieving food security in terms of their valuable contributions to agricultural sustainability, especially in developing countries, and the high nutritional value of animal products in the diet.
一项保守预测显示,与目前72亿的人口水平相比,到2050年世界人口将增长32%(达到95亿),到2100年将增长53%(达到110亿)。由于全球大部分可耕地已在使用,水和能源也受到限制,提高粮食产量将需要大幅提高效率。在本文中,我们强调动物对于实现粮食安全的重要性,这体现在它们对农业可持续发展的宝贵贡献上,尤其是在发展中国家,以及动物产品在饮食中的高营养价值。
