Perhaps it's because we live in a world wired with media that makes the suffering of the world ever-present in our lives.
Perhaps it's the influence of high-profile celebrities who have taken up the cause.
Whatever the reason, we have reached a crossroads in international awareness of global health. A surprisingly broad coalition of influential people is now championing development assistance and working to bring attention to the subject of global health. Eight in 10 Americans now believe we have a responsibility to help the neediest people around the world.
With this level of public support, our broad knowledge, and the effectiveness of existing tools, the world's wealthy nations can dramatically improve global health, increase the quality of life, and extend life expectancy for children and adults around the world.
