For everyone who thinks that this is not making a difference:
Yes, 29,000 grains are required to make a pound of rice, however 1 pound of rice feeds 9 people.
Secondly, look at their totals, 537,163,380 donated in October and 4,768,969,790 in November, and so far in December there has been around 4,000,000,000 (not actual number, but I eyeballed it pretty accurately). That is a grand total of 9,306,133,170 not counting the amount that's already been donated today! That's a little over 320,901 pounds of rice which can feed 2,888,110 people.
