Thanks for pointing out the sewage from the Israeli colonies polluting Palestinian land. I have come across this problem everywhere where I helped during the Palestinian olive harvest. The Jewish colonies, usually built on top of the hills and often without proper sewage facilities, simply and indeed with intent let their raw sewage run down hill into Palestinian orchards and villages. I have come across a huge hill in the Westbank, which consists entirely of garbage/detritus from within the Green Line and the colonies in the Occupied Westbank. And last but not least there is the separation wall. It has caused untold environmental destruction. It is a giant ragged laceration running over the Palestinian landscape for hundreds of kilometres. Although it is important for Palestinians to increase their environmental awareness, by far the biggest polluter in Palestine is the occupier, i.e. Israel and its colonists.
