There was never a point in which our environment was beyond all hope for future generations. It is still beautiful and natural, and the circle of life will continue. It is up to the people of this planet to nurture and heal our Great Mother and find alternate resources while others are being restored. I believe that our children's children will go back to the old ways of the world. Grow your own food, animals, etc. and take care of the land.
Every fifth generation repeats itself.
My great grandparents did the same. The world is a beautiful place and it doesn't take much to keep it that way.
