When I go back to NFL functions today, I feel a bit on the outside looking in. I played 13 years in the NFL, and I loved it - made a Pro Bowl and went to the playoffs - but I always felt like I was having to knock the door down to get in.
If you look at it ecologically, deforestation is high on the list of things which bring devastation. You cut down trees to build homes, for fuel, and you end up with no trees left, and you have to move on. If you take the earth as a whole, eventually there's nowhere to move on to.
