If I had a million dollars to spend, I would invest them in these two things:

Preventative secondary healthcare for rural areas:

They are not doctors. They are not nurses. They are illiterate women from India’s Untouchable castes. Yet as trained village health workers, they are delivering babies, curing disease, and saving lives—including their own.

and Cell Phones for developing areas :

Mobile phone ownership in India is growing rapidly, six million new mobile subscriptions are added each month and one in five Indian’s will own a phone by the end of 2007. By the end of 2008, three quarters of India’s population will be covered by a mobile network. Many of these new “mobile citizens” live in poorer and more rural areas with scarce infrastructure and facilities, high illiteracy levels, low PC and internet penetration.
