Zambian Mine Spill: Disaster 30 Times Worse Than Reported
A Chinese-owned copper mine in Zambia had a big accident where a wall holding back waste broke.
Instead of 50,000 tons, it looks like around 1.5 million tons of poisonous stuff spilled out.
This could mess up the water, fish, and farms nearby.
The U.S. Embassy is worried and pulled out some of its workers.
The Zambian government says the water is okay now, but the spill is still causing problems.
The company in charge of the mine is arguing with the company that tried to measure how bad the spill was.
Toxic spill at a China-owned mine in Zambia released far more waste than initially reported.
An independent assessment estimates 1.5 million tons of toxic substance escaped the mine.
The incident threatens water supplies, fishing, and farmland in the affected area.
The U.S. Embassy in Zambia expressed concern and ordered staff withdrawal from the area.
Zambian government officials maintain that water quality has been restored.
