I'm against Nuclear Energy because reactors can cause radioactive waste and become dangerous if any mistake happens would cause problems to the environment. The Radioactive waste can remain dangerous for many years and it could cause danger to the human health like Cancer.etc. Also, A terrorist could target a nuclear reactor to make weapons and it would be worst for the country and Environment. Nuclear plants are not cheap to build and  is not safe for the Environment. Is not safe to mine for nuclear materials used in nuclear plants like uranium and titanium run a very high risk of water contamination near by water supplies.
