Atomic energy when harnessed by man, for peaceful purposes, yields good results. Isotopes of some radioactive materials are used to cure diseases. Atomic energy is used to run reactors to produce electricity. It has proven to be a viable alternative to the fossil fuels. The isotopes are also used to sterilize crops and vegetables and keep them free from diseases. Carbon-14 is used by archaeologists to find the exact age of an organic fossil.
While science has been a boon to mankind, it has also proven to be a bane. It is because man does not use his foresight. In his pursuit of excellence, man ignores nature. In an attempt to civilize, he tampers with nature and causes immeasurable damage to it. Indiscriminate industrialization and urbanization have resulted in alarming levels of pollution. Man chokes the rivers with sewage, industrial wastes, and filth. The modes of transport have contributed to further deterioration of the planet and now pose a threat to the very existence of the flora and fauna.
