“Unspeakable riches have brought the people of the Congo little other than unspeakable pain.” So writes Siddharth Kara in Cobalt Red, How the Blood of the Congo Powers Our Lives . It’s one of the many poetic phrases that make this book easy on the ear but hard on the heart and mind. There’s pleasure in turning the pages of such finely crafted prose, pain in knowing that, if you have half a heart, you’ll never be able to see your smartphone, laptop, tablet, solar power system, or electric car quite the same way again, that you’ll see blood all over the supply chain that put them in your hand, on your roof, or in your driveway. Despite such privilege, you might even ask yourself how you can stand to live in such an evil, brutally predatory world for one more day. I did, but I read on and highly recommend this book despite that shaky moment.
