Answer:
North Carolina legislators changed coal ash storage requirements.
Explanation:
After the incident of Duke coal ash spill on February, 2014, there was a loud outcry by many people and environmental activist groups against the Duke Energy for spilling about 39,000 tons of coal ash into the Dan River.
There were numerous lawsuits against Duke Energy and the company had to pay billions of dollars as fine and reparations for the damage caused by them. As a result, the North Carolina legislators also passed a law which changed coal ash storage requirements. The law prohibited building of coal ash ponds near the state's lakes and rivers and stated that coal ash would be treated as any other industrial waste.
Due to social forces, the supreme court overturned a precedent in deciding the Brown vs. Board of Education case.
It was one of the events that touched all the problems and disputes of the first world war directly affected the conflicts and their ways of development from that.
