Thanks for the info on the Channel Islands. I was looking at a NASA photo of Lake Nasser and the border between water and land in Egypt. This leads to an analysis of agriculture in the desert and the corresponding climate change from evaporation. I may take it further by considering the border with Sudan and the name change of the Lake.
Then I plan to move on to photos of the Great rift and the potential border there. One idea just seems to flow into another. The Ecuadorian volcanoes eruptions, depending upon site can cause even more border problems. We have so many migrants here that push and pull factors are in daily evidence. That one didn't speak to me very much.
