Gene Splicing Genetic research has produced both exciting and frightening possibilities. Scientists are now able to create new forms of life in the laboratory due to the development of gene splicing. The ability to create life in the laboratory could greatly benefit mankind. For example, as it is very expensive to obtain insulin from natural sources, scientists have developed a method to manufacture insulin inexpensively in the laboratory. Another beneficial application of gene splicing is in agriculture. Scientists foresee the day when new plants will be developed using nitrogen from the air instead of the fertilizer. By this, food production could hopefully be developed to feed the world's hungry people. On the contrary, no one agreed on gene splicing. Some people think that it has terrible consequences. A laboratory accident, for example, might cause an epidemic of an unknown disease that could wipe out humanity. As a result of this controversy, the government made rules of controlling genetic experiments. In response to these rules, some members of the scientific community argue that the rules are too strict, whilst many other believe that they are still lenient.
