Don't simply give foreign aid. Give Micronutrients

Bjorn Lomborg writes:

Billions of dollars are given and spent on aid and development by individuals and companies each year. Despite this generosity, we simply do not allocate enough resources to solve all of the world's biggest problems. In a world fraught with competing claims on human solidarity, we have a moral obligation to direct additional resources to where they can achieve the most good. And that is as true of our own small-scale charitable donations as it is of governments' or philanthropists' aid budgets.

So, where will be the largest return on investment?

Micronutrient deficiency is known as "hidden hunger." This is a fitting description, because it is one of the global challenges that we hear relatively little about in the developed world. It draws scant media attention or celebrity firepower, which are often crucial to attracting charitable donations to a cause.
