That is already being done. The Department of Fisheries determines which animals go back to the wild, not VanAqua. The main detriment of this new ban is that now if there is a rescue that cannot realistically be later be returned to the wild after being rehabilitated, it will be necessary to euthanize instead.

And this is PETA's intention, they'd rather see an animal euthanized than be in captivity.

Ah yes, the let's-euthanize-the-Jews-instead-of-keeping-them-in-ghettos approach.
