At present, constantly search for new energy sources has been ever-rising as population and consumption of fossil fuels are soaring. Developed countries, today, to a greater exent relys on nuclear power to fullfill their energy demands. While people consider this source inexpensive, high quality and most significantly a way to have national security, it cannot be overlooked that the demerits it brings with us are far more concerning. For instance, threat to poor and under-developed countries. I strongly oppose this view of considering pros of nuclear power important over its cons.
