Argentina's Milei Dismantles Glacier Protection Law, Opening Andes to Mining and Risking Water Supplies

Argentina's President Javier Milei has pushed through reforms that effectively gut the country's landmark Glacier Protection Law, removing critical safeguards for high-altitude ice formations. This legislative rollback directly opens up vast Andean areas, previously off-limits, to mining and hydrocarbon exploration. Environmental activists and scientists warn the move poses a severe, immediate threat to the freshwater reserves that millions of Argentinians depend on, reserves already under intense strain from the climate crisis.

The 2010 law was designed to preserve glaciers and periglacial environments as strategic water resources and natural water regulators. Its weakening removes mandatory environmental impact assessments and public consultations for projects in these zones. The focus now shifts to the San Juan province, home to the Veladero gold and silver mine operated by Barrick Gold. Veladero has a history of contamination incidents, including a major cyanide spill in 2015 that polluted local rivers and sparked lasting fears for the Jáchal basin's water, followed by further spills in 2016 and 2017.

The implications extend far beyond a single mine. The legal change creates a precedent that could accelerate extractive projects across the Andes' fragile cryosphere. This places downstream communities, agriculture, and regional ecosystems in direct competition with mining interests for a dwindling resource. The decision signals a stark prioritization of short-term economic extraction over long-term hydrological security, setting the stage for intensified social conflict and environmental scrutiny in Argentina's mineral-rich provinces.
