19. Efforts to reduce pollution began occurring later in the century. If pollution near factories was reduced, what would happen to the color of the moths'Explain your answer.

If pollution near factories was reduced, the color of moths would likely revert to their original coloration. This is because industrial pollution typically causes surfaces to darken, leading to the prevalence of darker-colored moths, which blend in better with the environment. With reduced pollution, the surfaces would lighten, favoring lighter-colored moths. This phenomenon was famously observed during the Industrial Revolution with the peppered moth, where pollution-induced melanism led to a predominance of darker-colored moths.
