Explanation:
Chernobyl is the only, and most disastrous, human-caused nuclear incident in the entire history of human kind. It took place in 1986, when the nuclear reactor of the Chernobyl plant failed and all its nuclear istotopes issued forth into the atmosphere, affecting everything around it: Humans, animals and plants. The effects of Chernobyl are still being seen today, but probably the best known would be: the direct death of 31 people, without counting the ones who died immediately, the appearance of cases of thyroid cancer on people who were not directly exposed to the initial blast, but that still had the effects, and the destruction of animal and plant life that can still be seen today, after more than 3 decades.
