US military and deep-sea mining threaten Guam's environment

A new study published in the July 2026 edition of *Science* warns that two major activities are putting Guam's environment at risk. The United States military's expansion on the island, combined with plans for deep-sea mining in the surrounding Pacific Ocean, could cause significant ecological damage. Deep-sea mining involves extracting minerals from the ocean floor, a process that can disturb fragile marine habitats. The report, appearing in the journal's 393rd volume, highlights the need for careful assessment of these projects before they move forward. Researchers urge policymakers to balance economic and security interests with environmental protection.
