Sub-Saharan Africa has 80 percent of child cases. AIDS has and will not only cripple these economies, but it must also be taking its toll on the people. It is reasonable to support this in at least two ways. First, it is silly to not think of the world's problems as our problems. With ever expanding global communities and markets, it is impossible to completly separate ourselves from these nations.
Isolationism is incompatible in the modern world.
Second, it is the humanitarian thing to do. A major reason for the hard times in sub-Saharan Africa is a lack of information. Considering the high rates of children with AIDS, the problem is only going to get worse as more medical attention is needed. Three billion is an enormous sum of money. Obesity is a major problem facing our nation, with unforseen health problems in the future, and funding should be used.
