The historic Three Kids Mine property is undergoing extensive environmental remediation to clear lead, arsenic, manganese, and petroleum residues left behind from decades of military-era manganese production. Greenbow Park marks an early milestone in the broader transformation, providing local community recreation alongside views of the Las Vegas skyline. The surrounding acreage will eventually host more than 3,000 residential homes once the full site cleanup concludes. Federal legislation passed in 2014 made the land transfer and subsequent May 2024 cleanup kickoff possible through local redevelopment agencies.

What was once a mining site associated with potentially harmful industrial waste is now making way for neighbourhood parks, walking trails and thousands of homes. In Henderson, Nevada, a former manganese mine that operated for decades and left behind contamination is being transformed into a large residential community. The opening of Greenbow Park marks a new phase in that redevelopment. According to the Nevada Division of Environmental Protection (NDEP), the Three Kids Mine site has been the subject of extensive environmental assessments and a cleanup programme, with the estimated remediation cost reaching approximately $257 million.
From wartime manganese production to an abandoned mining site
The Three Kids Mine has a history dating back more than a century. Manganese ore was discovered at the site in Clark County, Nevada, in 1917. However, mining operations took place intermittently, including between 1942 and 1943 and again from 1953 to 1961. Manganese was an important industrial mineral, particularly during World War II, when demand increased for materials used in military equipment and steel production. According to the NDEP, an on-site processing mill was constructed…
Upstream damming, industrial diversion, and summer temperatures reaching 50 degrees Celsius are rapidly desiccating a vital Unesco World Heritage site along the Iran border. The ecological collapse is shattering historic wetland economies and triggering massive civilian displacement across the Maysan governorate. Indigenous Ma’adan communities now face the permanent loss of their traditional heritage and water supplies.
Months of record heat and severe drought have left critical reserves across Sussex at critically low margins, threatening supplies to nearly 100,000 households. The crisis is worsened by rising industrial and population demand alongside long-standing infrastructure failures that leave nearby water resources completely inaccessible. Consequently, mounting public alarm has grown following official advisories that urge families to stockpile essential supplies.
Severe drought linked to an El Niño weather pattern fueled massive land blazes across the archipelago, triggering a 42 percent surge in national air pollution fatalities. Fire emissions proved particularly devastating on Sumatra and Borneo, while the toxic transboundary haze spread to multiple neighboring Southeast Asian countries. At its peak, the environmental crisis exposed tens of millions of citizens to dangerous air quality.
