生态农业系统是多功能的,它不仅提供授粉、害虫控制、节水、再生性土壤肥力等技术性服务,它还提供生态多样性,而这种多样性会变成食物的营养。使用地方种子的生态农业每亩产出更多的营养,更多的健康。世界农业面临着一个重大选择,新的范式正在出现。新技术在各国的应用,特别是发展已有30多年历史的转基因作物研发、生产、食用所带来的全球性状况和问题,近年来引发诸多关注。很多对化学农业、绿色革命、 The eco-agricultural system is versatile and provides not only technical services such as pollination, pest control, water conservation, regenerative soil fertility and other technical services, it also provides ecological diversity that can turn into food nutrition. Ecological agriculture using local seeds yields more nutrients and more health per acre. World agriculture faces a major choice and new paradigms are emerging. The application of new technologies in various countries, especially the global situation and problems arising from the development, production and consumption of genetically modified crops that have been in existence for more than 30 years, has drawn much attention in recent years. A lot of chemical agriculture, green revolution,
