The use of Agent Orange has affected the lives of millions of people across the world, from America and Vietnam to Korea and New Zealand, among other areas.
However, Agent Orange’s legacy goes beyond the human cost, the environmental contamination is still a “significant issue” even now in Vietnam.
Dr Martini said: “Even in areas where it is difficult to show that Agent Orange was the cause of the problem (like the death of Hopper’s daughter), those families have lived in the shadow of Agent Orange, sometimes for decades.”
The show could delve further into Hopper’s backstory and his time in Vietnam when the show returns next month.
Stranger Things season 4, volume 2 will be released on Netflix on July 1
