If we want to be able to tackle global issues, we must utilize not 50 percent of our population, but all of our population. The time to act is now.
Epps did not love Patsey; he consumed her. He lusted and wielded his power over her, made her inhuman, made her want to die.
Presently, two-thirds of the world's illiterate population is female. This startling statistics paints a dim portrait of the effects of the gender education gap as a barrier to destroying global economic deprivation.
Too many girls are stifled by hunger, poverty, violence, a lack of education, and inequality. This year, Women Thrive Worldwide is putting a stake in the ground and saying enough is enough.
When we educate girls on their health, they feel empowered to take responsibility for their choices, to hold their wellbeing in high regard, to stay in school and to become productive adults, and to involve their parents and caregivers in meaningful dialogue.
Our girls stand as examples of what can be achieved when programs exist to get girls into the right academic environment.
What most touched me yesterday, however, was Malala's insistence that boys, our sons and brothers, are her partners in creating an equal world.
If we think it's acceptable to give only half our population opportunity, then we will reach only half of our potential. In this day and age, this shouldn't be a fight at all -- for anyone.
She's only 16, but Malala is many things: a champion for girls' right to education, a survivor, an inspiration, an older sister, and a role model.
The Day of the Girl is a way for everyone to do their part and demand more, so that no classroom door is ever closed on a girl, so that no girl is married off before her 15th birthday and so that every person has the opportunity to reach their full potential.
As families struggle to get by financially, girls are often pulled out of school to help care for siblings or to work for extra income. Schools can be overcrowded or non-existent for refugee children -- the very situation Hanan faced.
As two men who advocate for women -- and as fathers of girls -- we hoped Malala would become the youngest Nobel Laureate. But we'll take the consolation prize: Today is the UN day recognizes half of our children: The International Day of the Girl Child.
The International Day of the Girl is important. This is not another cause to celebrate for one day. Instead it is to recognize the need for investing in girls and raising their voices around the world. We need, grassroots movements, resources and political will to make this change a reality.
The International Day of the Girl is a fitting time to reflect on the countless girls like Harriet who might not achieve their dreams unless we mobilize to ensure they receive an education.
They are great in number, these girls; they belong to an exploding population of youth worldwide -- the largest in history. And these girls are bubbling with untapped potential that will continue to be squashed unless we put them at the center of global development efforts in the coming decade.
In honor of the event, some of the day's organizers asked me to grapple with the question, "Why is this day necessary?"
