Chemistry is involved in almost everything with which we come in contact. The life processes of all organisms involve chemical changes. Chemists play a key role in the development of drugs, which are helping to cure and alleviate diseases and prolong life span. Chemists are involved in biochemistry and genetic engineering . For example, there is much interest in producing new bacterial strains, which can synthesize useful products such as human insulin or interferon.
Chemists are also at the forefront of developing fields such as nanotechnology.
They are actively involved in environmental issues and are helping to tap new sources of energy to replace the earth's finite reserves of petroleum. Our high standard of living depends heavily on the contributions of chemists to agriculture, manufacturing, new technologies, and the development of efficient means of transportation and communication. Thus, with its broad scope, chemistry offers an exciting array of intellectual adventures and opportunities.
