8. A student wrote this paragraph to explain the causes of the trends in this graph. Most of the peppered moths in the industrial regions were dark in 1959 because air pollution had resulted in dark tree trunks and branches so the peppered moths needed to be dark so they would not be seen and eaten by birds. After 1959, air pollution was reduced, so tree trunks and branches became lighter. The peppered moths became half lighter so they would not be eaten by birds. In rural regions, there was little air pollution, so the tree trunks and branches were lighter and peppered moths did not need to become dark. Write a scientifically more accurate explanation of what happened to cause the trends in the graph.
