New Mexico has banned uranium mining on 13 million acres of state land. The decision protects vast stretches of land from mining activity. Uranium mining has a troubled history in the American Southwest.

Past mines left contamination that affected nearby communities for decades. The ban covers state-owned lands across New Mexico. It does not apply to federal or tribal lands.

Supporters say the move safeguards water, soil and public health. They point to the long-term costs of cleaning up old mine sites. The state has some of the largest uranium deposits in the United States.

Mining companies had shown interest in new projects as nuclear power demand grows. Environmental groups welcomed the decision. They called it a win for communities living near mineral-rich areas.

The ban reflects a wider debate over how to balance clean energy needs with land protection. Nuclear power needs uranium fuel, but mining it carries local risks. New Mexico’s move shows states can set their own limits.

Other states with uranium deposits will watch the outcome closely.
