More than 10 years ago, the Great East Japan Earthquake and Tsunami damaged the Fukushima Dai-ichi Nuclear Power Plant, resulting in a massive release of radioactive material into the environment. Radiation dose rates led to the evacuation of over 150,000 residents from an area estimated at 444 square miles. Although people were evacuated, wildlife remained within the Fukushima Exclusion Zone, as it is sometimes called, and generations of animals have since been exposed to radiation levels above the safety threshold for human occupancy.
