I don't think it's something that goes away once you build that relationship with nature especially young, it's too beautiful. I now live in the city and go out of my way to get "nature time" so no matter how busy life gets, he'll find his way there. Animals and their environments are to be respected even if it's going to be eaten is an important lesson.

I'm sure you are right, more big birds means there is probably more fish as well (also a sign of healthy waterways/environment).
