Genetic engineering has ushered in a new era in biology. Although many problems are still to be solved, there are examples that point to a possible later application for the benefit of mankind: Bacteria can be manipulated to degrade crude-oil spillages, to produce human insulin and to bind nitrogen from the air. If all the bacteria that are indigenous to agricultural soils could be made to bind nitrogen, an increase in soil fertility might well result.
基因工程开创了生物学的新纪元。尽管仍有许多问题有待解决，但已有实例表明，基因工程可能在未来造福人类：可以对细菌进行操控，使其降解原油泄漏物、生产人类胰岛素以及从空气中固氮。如果能使农业土壤中的所有原生细菌都具备固氮能力，那么土壤肥力很可能会提高。
