Slavery Footprint, a new website and mobile app that launched today (the 149th anniversary of the announcement of the Emancipation Proclamation) can tell you approximately how many slaves have pitched in to make the goods you enjoy on a daily basis.
The site, created in a collaboration between anti-slavery nonprofit Call + Response and the State Department’s Office to Monitor and Combat Trafficking in Persons, uses a complex algorithm to calculate how many slaves work for you based on a number of questions, including how much jewelry you own, whether you’re a gadget geek, what’s in your medicine cabinet, and even whether you’ve paid for sex (you’ll just have to check out the site to get the details on that one).
