We live on an island surrounded by the sea, so why is tidal power generation always getting blocked on "environmental grounds"?

A barrage from near Cardiff to Weston-super-Mare has been touted for many, many years, but it gets blocked to "protect migratory birds' feeding grounds". The whole idea is that rising sea levels are allowed past a barrage, then released through turbines before the tide starts to rise again. So the "feeding grounds" get exposed twice a day.
