The issue is extremely complicated with many questions to be asked and addressed.
If you are to say yes then the reasonings most would give is the continued energy usage we would gain from it. How this energy could be used to reduce the strain on the environment and how cost effective nuclear energy is in comparison to anything else in the world.
If you say no then it could be for the danger it poses to humans when used for bad or the waste it generates which can not be recycled or destroyed and just has to be buried. Don’t forget it’s extensive usage in nuclear weaponry as well.
