Quite true. Switching to hydrogen by itself won't solve the problem. It will simply switch the source of the pollution. So, how do we go about producing hydrogen in an environmental sound way? I remember reading something about a process of extracting hydrogen from sea water. Apparently such methods would have zero emissions. Maybe an engineer can it explain the process in simple terms and someone can tell us how far away we are from using such processes.
