I like how you made a point of enforcement. Regulations mean nothing if not enforced. As for the rebuilding, I love the idea. Rebuilding is so important when it comes to problems like habitat destruction. On the other hand, though, I always ask myself the consequences of undoing what has already been done. For example, tearing down a non-functional dam that has been there for decades may not actually give the outcome you want. It could just initiate another shock to the already recovering ecosystem. The fish adjusted to having the dam there, and breaking it could just do more damage than healing. I think that’s why issues involving restoration are hard.
