Using Slavery Footprint, find out how many slaves you indirectly employ through your lifestyle. People are trafficked into slavery at various stages of the supply chain, mining the tantalum that goes into your smartphone or harvesting the coffee beans that you drink. Knowledge is the first step to making a difference and will hopefully inspire you to stand up to the brands you love to pressure them to look more closely into their supply chain. Slavery Footprint – Made In A Free World.
