What should be our role in world health?

When I say "our" role, I mean you and I -people living their lives relatively free from the threat of hunger and rampantly spreading diseases.
My thought process was sparked by viewing a documentary that aired on the CBC, about photographers in the line of fire. There are many mind blowing and disturbing images of starving children and horrific statistics revealing death by numbers -but are we desensitized to all this as we sit comfortably in front of our TVs?
Journalist and author, Stephanie Nolen, appeared on The Hour, to talk about her new book, 28, a journal on AIDS in Africa and how desperate the situation has become due to world wide indifference.
I realize the task of lending a helping hand may appear daunting, but really the best thing to do is educate yourself and simply spread the word through advocacy.
