Answer: In the movie Dark Waters, the call from the Kigers is significant because it leads to the discovery of a link between unexplained cattle deaths and pollution caused by the chemical company DuPont.
Explanation: In the movie Dark Waters, the call from the Kigers is the key moment that sets off the plot. The Kigers, who are farmers in West Virginia, call Robert Bilott, a corporate defense attorney, and ask for his help in investigating the strange deaths of their cattle. Bilott is reluctant to take on the case at first, but he eventually agrees to visit the Kigers' farm and see the situation for himself.
During his visit, Bilott discovers that the Kigers are just one of many families in the area who have experienced unexplained deaths and illnesses among their livestock, as well as health problems among their own family members. Bilott begins to suspect that the cause of these health issues is pollution from a nearby chemical plant owned by DuPont, a multinational chemical company.
Bilott takes on the case and begins a long and difficult legal battle against DuPont, uncovering evidence that the company had long known about the dangers of the chemicals it was using - specifically a substance called PFOA, which was used in the production of Teflon - but had covered up the evidence and misled regulators and the public about the risks.
In the end, the call from the Kigers is significant because it leads to the discovery of a link between unexplained cattle deaths and pollution caused by DuPont, and sets off a series of events that ultimately lead to the exposure of corporate wrongdoing and the pursuit of justice for those affected by the pollution. The Kigers' call is a catalyst for change, prompting Bilott to take action and exposing the truth about a powerful and deceitful corporation.
