Finding an alternative energy source to fossil fuels is becoming increasingly important. This has led many countries to question whether nuclear power, touted as an environmentally friendly source of energy, is the answer. A look at the environmental effects attached to this source of energy—the risk of radiation exposure for communities adjacent to nuclear plants, and nuclear power’s volatile history—coupled with current events provides countries with reason to seriously doubt the safety and sustainability of this energy source. Nuclear plants do immediate damage to the system in which they are built, and that is not the end of their effects. Continuous release of radiological material into the surrounding area that threatens the ecology and nearby communities, the creation of waste, for which there is currently no solution, and a threat of radioactive materials falling into the hands of terrorist activists also weigh heavily against the sustainability of this energy source. The history of the nuclear industry makes it undeniable that more nuclear disasters are inevitable. Every community is vulnerable, whether a nuclear disaster is caused by nature’s wrath, as in Japan, or by human or technological error, as in many previous nuclear accidents, including Chernobyl. The countries of the world have a weighty decision to make about whether nuclear energy is the answer.
