> But there are many things that do need to be a federal concern

I completely agree! Most of them are already explicitly listed as federal concerns, in the Constitution; we should amend it to include environmental concerns for the exact reason you note.

But I see no reason why e.g. education should be a federal concern. Let the states do as they will.

Because there need to be national standards for education. The citizens of a state do not exist in a vacuum, and being taught Creationism instead of actual science is going to do great harm to those kids ability to get jobs, which is going to have an impact on many sectors of the economy.
