h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

Hi everyone,
Wanted to remind everyone that we are all a part of an everchanging world. In some ways it feels as if it's changing at a rapid rate of speed. There are for me at this point in time many questions that have to be asked.
1) In which ways has our society progressed?
2) Have any of the changes we've made thus far had a positive impact?
3) Why does there have to be a wall in the West Bank?
4) Are walls necessary in our society?
5) When will we learn to tolerate each other?
6) Am I the only one who is incredibly offended, nauseated, and upset when viewing pictures of said wall in last weeks New York Times?
7) If enough of us were and or are outraged could we change things in a
very real and positive way?
8) If you care about humanity and the progress and or digression that we have made in the past century please post an opinion.
Thank You,
Bright-eyed Teresa
