During the Industrial Revolution, vast quantities of trees were cut down to meet the increasing demand for wood, fuel, and land for agriculture and urban development. This deforestation led to significant environmental changes, including loss of biodiversity, soil erosion, and disruption of local ecosystems. Additionally, the expansion of industries and railways further contributed to habitat destruction and pollution. The consequences of these actions have had lasting impacts on forest ecosystems and climate change.
Burning of coal during the industrial revolution and later deposited soot on the trees.
Before the Industrial Revolution, the light peppered moth thrived due to its coloration, which allowed it to blend in with the predominantly light-colored tree bark and lichen in its natural environment. This camouflage provided effective protection from predators, leading to higher survival rates. As industrial pollution darkened the trees, the darker variant of the moth became more advantageous, ultimately shifting the population dynamics during the Industrial Revolution.

During the holiday season, more Americans opt for artificial trees rather than real trees.

If the trees were logged in a remote wilderness area, the usual method of transportation was to float them on rivers. In more developed regions, timber was transported by train.

The industrial revolution
Peppered moths serve as a classic example of natural selection, particularly during the Industrial Revolution in England. Before the revolution, the light-colored moths were more common due to their camouflage against lichen-covered trees, which protected them from predators. However, as pollution darkened the trees, the darker, melanic form of the moth became better camouflaged, leading to an increase in their population. This shift demonstrates how environmental changes can influence which traits are favored, resulting in changes in species over time.
Because before the industrial revolution, the bark of the trees they lived on was light, therefore the dark ones could be easily seen and eaten by predators, causing only the lighter ones to survive. When the industrial revolution came about, the trees near factories were covered in soot and blackened by the pollution, therefore the darker moths couldn't be seen and eaten so they survived wheras the lighter moths could be seen and eaten.
The industrial revolution in England (the black smoke form all the factory chimneys) produced allot of environmental pollution and the trees in the worst affected areas were covered in soot. Now thankfully this pollution has ceased and the tree trunks are no longer black...I understand that the areas of black peppered moth variants are now reverting to the light colored variety.
nothing happens to them
The large-scale cutting down of trees, often referred to as deforestation, began during the Industrial Revolution in the late 18th century when demand for resources increased. However, significant deforestation practices can be traced back to ancient civilizations that cleared forests for agriculture and urban development. Today, deforestation continues at an alarming rate, primarily driven by agriculture, logging, and urban expansion.
During the industrial revolution, peppered moths with dark coloration had better camouflage on soot-covered trees, allowing them to avoid predation and survive to reproduce. Over time, the frequency of dark-colored moths increased due to their enhanced survival, demonstrating natural selection operating on the population.
The melanic form of the peppered moth is darker in coloration compared to the typical light-colored form. This dark coloration is a result of a genetic mutation that causes an increase in the production of melanin pigments in the moth's wings. The melanic form of the peppered moth became more prevalent in polluted areas during the industrial revolution due to its increased camouflage on darkened tree trunks.
