When my children were young we took them camping a lot. This way we were able to show them nature and it wonders and how to pick up after your self so that you did not pollute nature so others can enjoy it too. I took this time to help my kids learn to live as one with nature to live off the land if you need to and to survive for a few days if need be. I did not go in depth with them and show them more as I felt they were not ready for that.
