The Red Cross is good, but if you want to make a direct impact try http://www.shelterbox.org/
these are the same people who sent out boxes full of essential items when New Orleans was hit by Katrina. You can even track where the box you donate to goes, so you'll be able to tell if your donation helped someone affected by the earthquake in Japan or the resulting tsunami in other locations. http://www.shelterbox.org/about.php?page=9
is what your donation buys. Each box costs £590, imagine how many boxes the people affected by this disaster are going to require and you can see why I recommend this charity who are out there now (and as this forum is mostly American, they have delivered to 3 locations in the US so maybe Karma will come into play!).
A strange obsession, mine. But better to be addicted to smartphones and gismos than cocaine or ***, I suppose. Well, I don’t know, the result is the same after all, very little sleep, great expense and horrific mess everywhere.
