Three organizations fighting global slavery and trafficking were collectively awarded $3 million by Google last week.
The money comes in the form of a Global Impact Award, which supports nonprofits that use technology to solve problems. Polaris Project, Liberty Asia and La Strada International are currently collaborating on a "Global Human Trafficking Hotline Network," which analyzes data from local hotlines to crack down on the lucrative -- and destructive -- practice of slavery.
According to a Google announcement about the awards, some 21 million people are enslaved across the world, generating $32 billion for those that profit from slavery.
The Global Impact Awards program was launched in December last year, when $23 million in grants were given to seven nonprofits. The organizations are trying to solve "the world's toughest human challenges," and tackle issues ranging from water to education to wildlife preservation.
