A good summary of the Israeli-Palestinian conflict, with many links, is on Wikipedia.
A current story on the uprooting of Palestinian olive trees is on the home page of Israeli Indymedia and a recent story can be found in the online edition of England's Guardian newspaper.
For images of uprooted trees, and other scenes from the conflict, see the Palestinian Red Crescent Society.
Here's an article on the subject of uprooting olive trees, found as a link off the Electronic Intifada.
Finally, here's a story from Caritas, a Catholic organization, which calls attention to the problem.
Hope this helps. RR
