An unflinching investigation reveals the human rights abuses behind the Congo’s cobalt mining operation—and the moral implications that affect us all. Cobalt Red is the searing, first-ever exposé of the immense toll taken on the people and environment of the Democratic Republic of the Congo by cobalt mining, as told through the testimonies of the Congolese people themselves. Activist and researcher Siddharth Kara has traveled deep into cobalt territory to document the testimonies of the people living, working, and dying for cobalt. To uncover the truth about brutal mining practices, Kara investigated militia-controlled mining areas, traced the supply chain of child-mined cobalt from toxic pit to consumer-facing tech giants, and gathered shocking testimonies of people who endure immense suffering and even die mining cobalt. Cobalt is an essential component to every lithium-ion rechargeable battery made today, the batteries that power our smartphones, tablets, laptops, and electric vehicles. Roughly 75 percent of the world’s supply of cobalt is mined in the Congo, often by peasants and children in sub-human conditions. Billions of people in the world cannot conduct their daily lives without participating in a human rights and environmental catastrophe in the Congo. In this stark and crucial book, Kara argues that we must all care about what is happening in the Congo—because we are all implicated.

In the modern era, slavery has been universally rejected and basic human rights are deemed erga omnes and jus cogens in international law. The ongoing exploitation of the poorest people of the Congo by the rich and powerful invalidates the purported moral foundation of contemporary civilization and drags humanity back to a time when the people of Africa were valued only by their replacement cost. The implications of this moral reversion, which is itself a form of violence, stretch far beyond central Africa across the entire global south, where a vast subclass of humanity continues to eke out a subhuman existence in slave-like conditions at the bottom of the global economic order. Less has changed since colonial times than we might care to admit.

The titanic companies that sell products containing Congolese cobalt are worth trillions, yet the people who dig their cobalt out of the ground eke out a base existence characterized by extreme poverty and immense suffering. They exist at the edge of human life in an environment that is treated like a toxic dumping ground by foreign mining companies. Millions of trees have been clear-cut, dozens of villages razed, rivers and air polluted, and arable land destroyed. Our daily lives are powered by a human and environmental catastrophe in the Congo.

The country’s first democratically elected prime minister, Patrice Lumumba, offered the nation a glimpse of a future in which the Congolese people could determine their own fates, use the nation’s resources for the benefit of the masses, and reject the interference of foreign powers that sought to continue exploiting the country’s resources. It was a bold, anti-colonial vision that could have altered the course of history in the Congo and across Africa. In short order, Belgium, the United Nations, the United States, and the neocolonial interests they represented rejected Lumumba’s vision, conspired to assassinate him, and propped up a violent dictator, Joseph Mobutu, in his place. For thirty-two years, Mobutu supported the Western agenda, kept Katanga’s minerals flowing in their direction, and enriched himself just as egregiously as the colonizers who came before him.

No one knew at the outset that the Congo would prove to be home to some of the largest supplies of almost every resource the world desired, often at the time of new inventions or industrial developments—ivory for piano keys, crucifixes, false teeth, and carvings (1880s), rubber for car and bicycle tires (1890s), palm oil for soap (1900s+), copper, tin, zinc, silver, and nickel for industrialization (1910+), diamonds and gold for riches (always), uranium for nuclear bombs (1945), tantalum and tungsten for microprocessors (2000s+), and cobalt for rechargeable batteries (2012+). The developments that sparked demand for each resource attracted a new wave of treasure seekers. At no point in their history have the Congolese people benefited in any meaningful way from the monetization of their country’s resources. Rather, they have often served as a slave labor force for the extraction of those resources at minimum cost and maximum suffering.

Lithium-based chemistries became the dominant form for rechargeable batteries because lithium is the lightest metal in the world, which has obvious benefits for consumer technology and electric vehicle applications. Cobalt is used in the cathodes of lithium-ion batteries because it possesses a unique electron configuration that allows the battery to remain stable at higher energy densities throughout repeated charge-discharge cycles. Higher energy density means the battery can hold more charge, which is critical to maximize the driving range of an electric vehicle between charges.

Contamination by heavy metals of the local population and the food supply was causing a range of negative health consequences across the Copper Belt. For instance, Germain had recently documented a high rate of birth defects in mining communities, such as holoprosencephaly, agnathia otocephaly, stillbirth, miscarriages, and low birth weight.10 Germain said that in most cases, the child’s father had been working as an artisanal miner at the time of conception and that samples of cord blood taken at birth revealed high levels of cobalt, arsenic, and uranium. Respiratory ailments were also common—“Inhalation of cobalt dust causes ‘hard metal lung disease’ which can be fatal,” Germain said. […] Cancers were also on the rise in artisanal mining communities, especially of the breast, kidney, and lung. “Exposure to nickel and uranium are the biggest causes of cancer,” Germain said.

Let’s say a decent wage for adults might accomplish all of this and more—who should pay it? Foreign mining companies would argue that they do not employ artisanal miners, so the responsibility is not theirs, even though the cobalt from artisanal digging ends up in their supply chains, and even though in some cases they allow artisanal miners to work on their concessions to boost production. The government of the DRC would argue that they do not have the money to support good wages or other income schemes, even though mining concessions are sold for billions of dollars and royalties and taxes in the billions are collected each year based in no small part on the value of the minerals excavated by artisanal miners. Cobalt refiners, battery manufacturers, and tech and EV companies would argue that the responsibility should be borne downstream, even though the scramble for cobalt only exists because of their demand for it. Therein lies the great tragedy of the Congo’s mining provinces—no one up the chain considers themselves responsible for the artisanal miners, even though they all profit from them.

This land that is home to the world’s largest reserves of an element crucial to the manufacture of the most dominant form of rechargeable energy in the world still awaits the arrival of electricity.

Leopold’s Force Publique coerced the native population to extract rubber sap from the vines of rubber trees deep in the Congolese rain forest. They whipped natives into submission using the chicotte, a flesh-shredding whip fashioned from twisted hippopotamus hide. They kidnapped the wives and children of village men and ordered them to meet a quota of three to four kilos of rubber sap per fortnight. If they returned from the forest without meeting their quotas, the hands, noses, or ears of their loved ones were chopped off. Rubber exports from the Congo Free State increased ninety-six-fold from 1890 to 1904, making it the most profitable colony in Africa.

Lumumba wrote to the United Nations asking for assistance in expelling the Belgians and reunifying the country. The UN responded with the largest ground operation since its creation to help stabilize the nation, but the forces were not authorized to expel Belgian troops. Lumumba turned instead to the Soviet Union for help. The possibility that the Congo, and especially Katanga, might come under Soviet influence put the United States, the United Nations, and Belgium into overdrive to dispatch Lumumba. On August 18, 1960, President Dwight Eisenhower met with his national security council to discuss the situation in the Congo and proclaimed that the U.S. had to “get rid of this guy.”The CIA hatched a plot to assassinate Lumumba using toothpaste poisoned with cobra venom; they settled instead on a plan to recruit Lumumba’s friend and the head of the army, Joseph Mobutu, to overthrow him.
