This map should scare the crap out of all of us. As should this story. As should the fact that successive governments have shown no inclination to take this issue seriously, and to search for solutions. Instead, we all stumble along, taking short term decisions with no thought of long term consequences, then undoing those decisions when reality bites (Remember this other story of Coca Cola being asked to shut three plants down because, groundwater?), and moving on to make equally wrong decisions someplace else.
