There are a lot of victims of Hurricane Harvey, and it looks like there are going to be potentially more from Hurricane Irma. I found a charity called Gleaning for the World, they can turn a $1 donation into $103 of product. They're the most efficient charity I've ever encountered, so I think they can get a lot of work done for these survivors.
Also, they've already been shipping drinkable water down to Houston, and they're getting ready to ship drinkable water down to Florida at a moment's notice. Pretty good.
