It's something I passed on to my kids. They really love the earth because they've experienced it from the youngest age. They know where food comes from - it doesn't come from the Safeway bush or the Ralph's tree. It comes from the earth. And water and sunshine and nutrients. My children understand that because they've experienced it. I feel successful as a parent, having done that.
