What are 3 cons of fusion?

Can you elaborate on the potential drawbacks of fusion energy, particularly focusing on three major concerns? Are there safety hazards that need to be addressed, such as the risk of radioactive materials leaking? Are there significant economic challenges, like the high cost of developing and maintaining fusion reactors? Lastly, are there environmental implications to consider, like the disposal of byproducts or the potential for disruptions to local ecosystems? Understanding these cons is crucial in evaluating the feasibility and desirability of fusion as an energy source.
