It must have seemed like an impossible challenge more than 150 years ago, that the moral imperative to end the slave trade and injustice it inflicted on Africans could actually succeed. Back then, slavery was considered ethically acceptable and economically necessary. Still, abolitionists won. They got slavery outlawed.
But the job isn’t finished, and we now follow in their footsteps.
Today, it might seem equally impossible to liberate 40 million people from modern forms of slavery around the world. But we will win, again.
