environmental disaster

On 26 April 1986, reactor 4 at the Chernobyl Nuclear Power Plant near Pripyat in Soviet Ukraine exploded, releasing radioactive material across Europe and forcing the evacuation of 350,000 people. The disaster exposed systemic flaws in Soviet reactor design and safety culture that would reverberate for decades.

In 1953, the Hooker Chemical Company sold a 16-acre abandoned canal site in Niagara Falls, New York, to the local school board for $1—knowing it contained nearly 22,000 tons of toxic industrial waste. Over the next 25 years, the buried chemicals seeped into homes, poisoned residents, and sparked America's first major environmental justice crisis.
