Industrial Revolution's Dark Legacy: Pollution's Rise

The Industrial Revolution, which began in the mid-18th century, brought about rapid economic growth and significant advancements in production, efficiency, transportation, and living conditions. However, this period also introduced severe pollution and environmental degradation due to the increased use of fossil fuels, particularly coal, and the mass migration of people to cities. The burning of coal and the hastening of deforestation led to increased carbon dioxide emissions, causing air pollution and contributing to climate change. As cities expanded rapidly, overcrowding, inadequate sanitation, and water pollution further exacerbated the health impacts of pollution on the working class, leading to respiratory illnesses and higher death rates. The Industrial Revolution marked a turning point in human history, but it also had unintended consequences, including the release of numerous pollutants and long-term damage to the environment.

Fossil fuels

The Industrial Revolution, which took place between the eighteenth and nineteenth centuries, marked a significant transformation in the nature of economies in Britain and several other countries. This period witnessed a massive increase in energy use, primarily obtained by burning fossil fuels like coal, which powered the development of new industries and transport systems. The heavy machinery and factories central to industrialization required vast amounts of energy, which was mostly derived from fossil fuels. This shift marked the beginning of a dependency on fossil fuels that still persists today.

The burning of coal and other fossil fuels released large amounts of carbon dioxide (CO2) into the atmosphere, contributing to global warming and climate change. According to the U.S. National Oceanic and Atmospheric Administration, the amount of CO2 in the atmosphere in 2022 was over 50% higher than in the pre-industrial period. The increase in CO2 emissions during the Industrial Revolution had a measurable impact on the climate, with signs of warming detected as early as the 1830s.

In addition to carbon emissions, the burning of fossil fuels also released other harmful pollutants such as smoke, sulfur dioxide, nitrogen oxides, and particulate matter. These pollutants contributed to smog, acid rain, and hazardous air quality conditions in many industrialized cities. The production of goods in factories also caused pollution through the discharge of chemicals and hazardous substances into waterways and land.

The reliance on fossil fuels during the Industrial Revolution had far-reaching consequences, setting in motion a pattern of unchecked resource exploitation, high emissions, and environmental degradation that continue to pose challenges today. The environmental impact of the Industrial Revolution, including the large-scale use of fossil fuels, marked the start of our intensive use of these non-renewable resources, driving climate change and global warming.

Deforestation

The Industrial Revolution, which spanned from the mid-18th to the mid-19th century, was a period of scientific and technological development that transformed Britain and other countries' economies. This period also marked a new increase in carbon dioxide (CO2) in the atmosphere, which impacted the climate. John Perlin, a visiting scholar in the department of physics at the University of California, Santa Barbara, attributes this rise in CO2 levels to two main factors: the burning of coal and the acceleration of deforestation in regions like America.

The Industrial Revolution's shift to a manufacturing-based economy, powered by heavy industrial machinery, led to a surge in energy consumption. This energy demand was met largely by burning coal, which replaced wood as the primary fuel source. As a result, deforestation rates initially slowed as coal became the preferred fuel for factories, ships, trains, and homes.

However, deforestation soon accelerated again as the growing population and expanding cities required more land for housing and infrastructure. This was particularly evident in North America, where English colonists cleared forests between the eastern seaboard and the Mississippi River. The construction of railroads, a symbol of America's rapid progress during this period, also contributed to deforestation. By 1850, there were approximately 3.2 million miles of wooden railroad ties and fences in the United States, which required a significant amount of timber.

The increasing industrialization and urbanization during the Industrial Revolution led to a tripling of the US population between 1850 and 1900, from 23 million to 76 million. This rapid population growth fueled the demand for more land, leading to extensive deforestation. Additionally, the growing steamboat industry, with its wooden vessels and fuelwood consumption, further contributed to tree-cutting.

The impact of deforestation during the Industrial Revolution extended beyond the immediate loss of forests. Trees store carbon dioxide, so deforestation released additional greenhouse gases into the atmosphere, exacerbating climate change. Deforestation also disrupted ecosystems, reduced biodiversity, and impacted the water cycle and weather patterns.

Industrial machinery

The Industrial Revolution, which began in the mid-18th century and lasted until the mid-19th century, marked a significant period of scientific and technological development. This period witnessed the advent of heavy industrial machinery, which played a pivotal role in enhancing production and efficiency. While the Industrial Revolution brought about economic growth and advancements, it also had a profound impact on the environment, with pollution levels surging due to the extensive use of industrial machinery.

The shift towards a manufacturing-based economy, powered by industrial machinery, led to unprecedented increases in production and efficiency. Innovations such as the steam engine, mechanized textile production, and railways revolutionized industries, enabling faster and more efficient production and transportation. This revolution in manufacturing processes marked a departure from traditional methods that relied on agricultural assistance. The use of heavy machinery, however, came at a significant environmental cost.

The use of coal-fired machinery in factories and residential heating contributed to the thick smog that enveloped industrial cities. The skies above cities like Manchester, known for its innumerable chimneys, were darkened by the pollution emitted from these coal-powered machines. The air pollution posed significant health risks to residents, with respiratory illnesses and higher death rates observed in areas with higher coal consumption.

In addition to air pollution, the use of industrial machinery also contributed to water pollution. Improper industrial practices led to waterways being contaminated with oil, debris, and other waste. The lack of knowledge and implementation of sanitary measures further exacerbated the issue, as sewage and waste were often mixed into drinking water supplies, leading to outbreaks of water-borne diseases such as cholera and typhoid.

The extensive use of industrial machinery during the Industrial Revolution had far-reaching consequences, with pollution levels surging to unprecedented heights. The burning of fossil fuels, coupled with the increased demand for coal, resulted in environmental degradation and a sharp increase in carbon emissions. The impact of this pollution was felt not only in the air but also in the water, as industrial practices contaminated waterways, posing health risks and leading to devastating epidemics in overcrowded cities.

Urbanisation

The Industrial Revolution, which began in Britain and then spread across Europe and North America, transformed societies by introducing mass production and advancing transportation systems. This revolution led to a massive increase in energy use, primarily obtained by burning fossil fuels like coal. The use of coal, a key factor in powering factories, ships, and trains, significantly increased carbon dioxide (CO2) emissions.

As a result of these advancements, urbanisation intensified. Cities expanded rapidly to accommodate the growing workforce needed for factories. Immigrants from rural areas were drawn to cities by the promise of paid work, only to find themselves living in crowded and polluted slums. The streets of these new cities were often designed for commerce, neglecting human needs such as privacy and recreation. This led to urban overcrowding, with inadequate sanitation and refuse collection systems, further exacerbating the pollution problem.

The increase in urban populations also put pressure on natural resources. Deforestation occurred as cities grew to make way for more housing and factories, releasing more carbon dioxide into the atmosphere. The combination of burning coal and deforestation contributed to the early signs of climate change, with scientists detecting warming temperatures as early as the 1830s.

While urbanisation during the Industrial Revolution brought about economic growth and improved living standards for some, it also had significant downsides. The release of toxic atmospheric pollutants from industrial activities in densely populated urban areas had detrimental effects on human health. Diseases such as cholera and typhoid spread due to inadequate sanitation systems, impacting the health of urban populations, especially those living close to industrial sources.

Water pollution

The Industrial Revolution of the mid-19th century introduced new sources of water pollution. The technological innovations that boosted the economy of Europe and the US caused air and water pollution. As factories released pollutants directly into rivers and streams, the waterways were polluted with oil and debris from improper industrial practices. For example, the Cuyahoga River in the US saw a rise in chemical waste, causing it to burst into flames and showcasing how industrial pollution destroyed natural resources.

The improper disposal of sewage, debris, oil, and other waste drained into waterways, causing water quality issues. This was not a new problem, as for centuries, humans had unknowingly contaminated drinking water sources with raw sewage, leading to diseases such as cholera and typhoid. The overcrowding in cities during the Industrial Revolution led to a lack of sanitation and unhealthy living conditions, with limited access to water for personal hygiene. This contributed to the spread of diseases like typhus and tuberculosis.

The pollution of waterways became such a serious problem in England that it prompted JC Morrell of the Manchester Statistical Society to write about it. The Rivers Pollution Act, a government bill introduced in 1875, attempted to address water pollution. However, it was criticised for being ineffective and allowing the continuation of polluting activities. Despite the legislation, water pollution remained a significant issue, with the General Board of Health forced to intervene during the cholera epidemic of 1848-1849.
