Never release captive raised animals...
I should have worded it better: unless you are a professional and/or are trained on what to do, how to do it, etc. do not release captive raised animals- you most likely are doing more harm than good...

It's man who is hurting these animals by taking their land, we need to help them.
Yep, that's why my father and I are members of conservation groups (Ducks Unlimited).
