Talking about managing it better sounds good but we still don't have public information tell us how much previous mistakes have affected our world. E.G Japan. Chernobyl.
Odd massive warm section off the coast, wonder what caused that? And the radioactive water dropped into the ocean? We may have long term affects on our food chain that we're not yet aware of.
It's a risk. Other renewable energy sources might be a better choice because it can be distributed power. Everyone can invest in their own power if it becomes efficient and cheap enough, it's almost there and is there for a lot of people already.
It's better than investing all our resources into a single power distributor, which if there are problems, we all have problems.
