Mexico’s Mercury Boom is Poisoning People and the Environment (Associated Press)

In Mexico’s Sierra Gorda mountains, soaring international gold prices also have created a mercury boom. Since 2011, mercury prices have skyrocketed from $20 per kilogram to between $240 and $350 per kilogram today. Most of Mexico’s mercury is trafficked to Colombia, Bolivia, and Peru for use in illegal Amazon gold mining operations that contaminate rivers and ecosystems. Yet the country’s adoption of a 2017 UN convention banning mercury mining and exports also allows artisanal mines to operate until 2032.

While the devastating cyclones Dineo (2017) and Idai (2019) may feel like distant memories on the global stage, their impact remains etched into daily life in Zimbabwe’s Tsholotsho and Chimanimani districts. A punishing regional drought in 2024 makes the picture here even clearer: food, land, and water systems have been reshaped in ways that directly influence social cohesion and stability.

Chinese Company Accused of Covering Up Extent of Major Toxic Mining Spill in Zambia (Associated Press)

In February, a dam collapse at Chinese-owned Sino-Metals Leach Zambia copper mine released toxic waste into the Kafue River, which provides water for over half of Zambia’s 21 million people. An independent investigation by South African company Drizit found that 1.5 million tons of toxic material were released in the spill, which is 30 times more than Sino-Metals admitted to spilling. When Drizit’s investigation was set to reveal extensive contamination verified through 3,500 samples, Sino-Metals terminated their contract one day before the final report was due.

Bolivian Presidential Vote Raises Environmental Concerns (Associated Press)

Bolivia’s presidential runoff election on October 19 between centrist Senator Rodrigo Paz and right-wing former president Jorge “Tuto” Quiroga has seen both candidates promise change. Yet Indigenous and environmental leaders remain skeptical that either hopeful will effectively address Bolivia’s severe environmental crises.

The Indus Waters Treaty of 1960 has kept two nuclear-armed rivals – India and Pakistan – in a stable river sharing arrangement for more than six decades. Yet that significant achievement now seems to be at risk.

India’s government has stated it is holding the treaty in abeyance and is threatening to cut off water to Pakistan after a terrorist attack killed more than 20 Indian citizens in late April 2025. India’s Prime Minister Narendra Modi described the treaty as a “blunder” and a “betrayal” of India’s dignity committed by then Prime Minister Jawaharlal Nehru, and proclaimed that “blood and water cannot flow together.”

The Mining Town Funding Congo’s Rebels and Tech Giants (Reuters)

In April 2024, the M23 rebel group seized control of Rubaya, a mining town that produces 15% of the world’s coltan—a critical mineral worth used in mobile phones, computers, and aerospace components. Rebels imposed a parallel administration in the town, and placed a 15% tax on mineral traders that generates $800,000 monthly from levies. Thousands of impoverished miners in the town, however, still work 12-hour shifts in dangerous conditions earning just $5.15 per day.
