Science has much to contribute to global food security. While genetic modification is not essential to feed the world, it does provide significant advantages, enabling scientists to introduce or enhance traits – virus resistance in cassava, for example, or improved digestibility of feed – that cannot be realized with conventional breeding.
科学可以极大地有利于全球食品安全。尽管转基因技术无法养活全世界，但它的确提供了重大进步，使科学家能够进行或改良传统饲育无法达到的特性，比如让木薯变得抗虫和让饲料变得更加容易消化。
