You are dead right! Its starting even now. I watched a thing with an Al Gore thing that explained why there are so many folks from Latin America fleeing. We have been told, by just about everybody, that it has to do with violence and gangs. That is certainly part of it but there is now a huge area of Latin America undergoing drought and they have been experiencing it long enough that they are now running out of food.
As far as I know this is the first disaster but there are sure to be others following. Its a shame that Jackass can't bring himself to explain the true reason for this migration and the fact that its likely to get MUCH WORSE!
