Child marriage perpetuates poverty and affects the lives of 10 million girls in dozens of countries around the world every year. That was the message Archbishop Desmond Tutu offered Tuesday at the 2011 Clinton Global Initiative Annual Meeting.Girls Not Brides: The Global Partnership to End Child Marriage was announced at CGI by Archbishop Desmond Tutu and Mary Robinson of The Elders; Ford Foundation President Luis Ubinas; and NoVo Foundation President and Co-Chair Jennifer Buffett."This harmful practice contributes significantly to core development challenges - poverty, education, maternal and child health, HIV and gender equality," said Robinson, President of Ireland from 1990 to 1997. "Yet, disturbingly, it has remained on the sidelines of mainstream development debate."
