Don't buy, give.

Why are people attached to the idea that buying something is an efficient way to help a cause? Think about it this way, this organization claims that "Each bag purchased feeds a hungry child for an entire year in school, and each t-shirt feeds 100 hungry kids for a day". How many more children would be fed if you simply gave your money to them and didn't receive a t-shirt or bag in return? Say 100% of the money goes to feeding the children instead of manufacturing the bag or tshirt, not to mention the rest of the mess created by the shipping, etc. Don't buy, give.
