Experts predict that by the middle of this century, fossil fuel would be so scarce that it would be expensive to drill and process fossil fuel. Our population is growing and there is a greater demand for fuel to keep up with the continuing industrialization. Scientist are compelled to find cheaper ways to produce electricity but how can we really benefit from nuclear energy? Many see the development of nuclear power as the most viable replacement for the use of fossil fuels in producing electricity. It has something to so with its capability to produce large amount of energy from small amounts of fuel. Presently almost twenty percent of the world's electricity come from nuclear plants. One thing it is considered environment-friendly since they do not emit sulfur and other pollutant like carbon dioxide. However the nuclear industry must find a replacement for U-235 because it is a scarce type of uranium.
Because of the health hazards, many have opposed the use of nuclear plant. They did not know that nuclear energy can also be used to save lives and cure diseases. Nuclear energy serves as an aid to medicine in the form of radioactive isotopes which are used to locate tumors and used to treat cancers.
Due to the high rate of food spoilage all over the world, nuclear energy is used in preserving food through irradiation. The food is exposed to gamma rays from radioactive cobalt-60 for a controlled number of minutes, to eliminate bacteria and other harmful organisms or poisonous substances that the food may contain. Nowadays, it is being used on many kinds of food products especially meat products and on fruits and vegetables too.
Many are still objecting to food irradiation but scientist said that the main purpose of irradiation is to kill the bacteria on food. Irradiation has no harmful effects known as of the present although they admit that it has reduced the amount of vitamins A, B, C, and E. It can control insect pests and improve reproduction of animals as well as to achieved mutated plants and agricultural crops.
The development of nuclear energy is relatively young and so many possibilities have remained unexplained. But there are drawbacks to the use of nuclear power, exposure of the human body to nuclear wastes can cause cancer. Another drawback is one of the worst fears of many, it can be used for mass destruction. Just like all other things in this world, nuclear energy can either be useful or subjected to abuse.
