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

In the population of pepper moth two varients exist the dark and the light coloured. Before industrialisation, the light coloured moths were prevelent because they blended well with the lichen convered bark of the trees.
The predators were unable to spot them and hence, their population were more in number. with industrialisation, the bark got covered with soot. The growth of lichens reduced , the light coloured moths were thus, spotted by the predators and their number decreased.
However, the black variants were camouflased better on soot covered barks nad their number increased drastically.
If the industries were removed, the population of black moths would have declined because as statd before, they would not be able to camouflage against a light background ( no black soot ). Also the growth of lichens would increase. Therefore, the dark varients would be spotted better by predators and be eaten more frequently.
