You have studied the story of peppered moths in England. Had the industries been removed, what impact could it have on the moth population ? Discuss.

Explanation

**Step-by-Step Text Solution:**

1. **Understanding the Context**: The peppered moth (Biston betularia) is a classic example of natural selection. The question asks us to consider the impact on the moth population if industries were removed from England.

2. **Pre-Industrial Scenario**: Before industrialization, the environment was relatively clean, and lichens thrived on tree barks. The tree barks had a grayish color due to the presence of lichens. In this scenario, the light-colored (peppered) moths blended in well with the tree barks, making them less visible to predators.

3. **Post-Industrial Scenario**: With the onset of industrialization, pollution increased, leading to the deposition of soot on trees. This soot caused the tree barks to become darker, which in turn made the light-colored moths more visible to predators. Consequently, the dark-colored moths had a survival advantage because they were better camouflaged against the soot-darkened trees.
