Industrial Revolution's Dark Legacy: Pollution's Deadly Toll

The Industrial Revolution, which began in the mid-18th century, brought about rapid economic growth and technological progress. However, it also had significant negative consequences, particularly regarding pollution and environmental degradation. The use of fossil fuels like coal to power new machinery led to increased carbon emissions and severe air pollution in industrial cities. Waterways became heavily polluted with oil, debris, and sewage, causing diseases such as cholera. The environmental impact of the Industrial Revolution was so profound that it set the stage for the large-scale carbon emissions that continue to drive global warming today.

Air pollution from coal burning

The Industrial Revolution, which began in the second half of the 1700s and stretched into the early 1800s, was a period of enormous change in Europe and America. The invention of new technologies revolutionized industries and societies, transforming what had been largely rural societies of farmers and craftsmen into fast-growing cities filled with machinery.

Coal was the primary energy source powering the newly developed steam engines, and it played a crucial role in the Industrial Revolution. However, burning coal had a significant impact on air pollution. As industrial cities and their factories relied heavily on coal, air pollution increased drastically in these areas. London's concentration of suspended particulate matter, also known as soot, rose dramatically between 1760 and 1830. Pollution in Manchester was also notorious, with writer Hugh Miller describing "innumerable chimneys [that] come in view, tall and dim in the dun haze, each bearing atop its own pennon of darkness."

The burning of coal released toxic airborne pollutants and heavy metals into the environment, causing respiratory illnesses and higher death rates in areas that burned more coal. Mercury, for example, is a toxic heavy metal emitted by coal plants, which can damage the nervous, digestive, and immune systems. It poses a serious threat to child development, with even small amounts deposited in lakes making fish unsafe to eat. Other harmful pollutants emitted by coal-fired power plants include lead, cadmium, carbon monoxide, volatile organic compounds, and arsenic.

The air pollution from coal burning had far-reaching consequences, affecting both mortality and health. It also impacted child development, as evidenced by studies of soldiers who enlisted during World War I and were born in England and Wales during the 1890s. The negative effects of coal pollution on quality of life and growth were significant, despite arguments to the contrary. Eventually, the environmental and health impacts of coal burning slowed down economic growth as the knock-on effects, or 'externalities', became more apparent.

The Industrial Revolution laid the groundwork for our modern technology-driven society, but it also marked the start of our intensive use of fossil fuels, which continues to drive climate change. The environmental consequences of this era, including air pollution from coal burning, were profound and continue to be felt today.

Water pollution from oil and debris

The Industrial Revolution, which began in the second half of the 1700s and lasted until the early 1800s, brought about significant advancements and progress. However, it also had detrimental effects on the environment, particularly in terms of water pollution from oil and debris.

Water pollution was a pressing issue during the Industrial Revolution, especially in industrialized cities. The rapid urbanization and population influx into these cities led to overpopulation, which, coupled with a lack of knowledge about sanitary practices, resulted in water contamination. Sewage and waste were often mixed with drinking water, providing ideal conditions for diseases like cholera to thrive. London, for instance, witnessed a cholera outbreak between 1848 and 1849, claiming the lives of around 15,000 people.

The extensive use of coal fired factories and residential heating contributed significantly to water pollution. The Thames River, flowing through London, became a dumping ground for industrial waste. The burning of coal released vast amounts of pollution into the atmosphere, leading to the formation of thick smog that darkened the skies over industrial cities. This particulate matter, including soot, not only affected air quality but also settled on water bodies, contaminating them.

As industrialization progressed, the reliance on fossil fuels, including oil, intensified. Oil-powered machinery, along with improper industrial practices, led to waterways being polluted with oil and debris. This pollution had disastrous consequences, as evidenced by the Cuyahoga River in Ohio, which became heavily polluted with oily debris and waste. The river caught fire on multiple occasions between 1936 and 1969, with the most well-documented case occurring in 1969 when sparks from a passing train ignited the build-up of oil and debris.

The environmental consequences of water pollution during the Industrial Revolution were far-reaching and persistent. The pollution of waterways with oil and debris not only posed immediate hazards, such as fires, but also contributed to long-term environmental degradation and public health issues. The Clean Water Act, enacted in 1972, was a response to water pollution crises like the Cuyahoga River fires. This legislation provided funding to improve sewage treatment plants and set limits on industrial discharges into waterways.

Health risks and respiratory illnesses

The Industrial Revolution, which began in the second half of the 1700s and continued into the early 1900s, brought about enormous societal changes in Europe and America. The shift to manufacturing-based economies powered by fossil fuels like coal led to a sharp increase in carbon emissions and harmful environmental pollution. This pollution had a significant impact on public health, with respiratory illnesses becoming a particular concern.

During the Industrial Revolution, cities like London, Manchester, and Birmingham expanded rapidly to accommodate the growing workforce needed for factories. These urban centers became heavily industrialized and polluted. The burning of fossil fuels, especially coal, pumped vast quantities of pollution into the atmosphere, leading to a significant increase in air pollution. The concentration of suspended particulate matter in London and other industrial cities rose dramatically between 1760 and 1830.

The poor air quality had severe consequences for the health of the population, causing respiratory illnesses and higher death rates in areas that burned more coal. In addition to outdoor air pollution, indoor air quality was also a concern. Many people lived in overcrowded and poorly ventilated homes, further exacerbating respiratory problems. The writer Hugh Miller described Manchester's atmosphere as "the lurid gloom of the atmosphere that overhangs it."

The Industrial Revolution also introduced new occupational hazards, especially in factory work. Workers were exposed to dangerous chemicals, dust, and other respiratory irritants without adequate protection. Lung diseases became a common issue, with workers suffering from respiratory illnesses due to inhaling harmful substances in the factories. The mechanization of previously hand-crafted industries, such as textiles, exposed workers to new health risks as they worked long hours in unhealthy conditions.

While the Industrial Revolution brought about many advancements, it also had detrimental effects on respiratory health. The burning of fossil fuels, rapid urbanization, and the introduction of new occupational hazards all contributed to an increase in respiratory illnesses and overall health risks for the population. These issues prompted debates about public health and led to the development of public health improvements and the formation of the basis of what we now call public healthcare.

Environmental degradation

The Industrial Revolution, which began in the mid-18th century, introduced new technologies that transformed societies and economies. While it brought about economic growth and advancements in transportation systems, it also had a profound impact on the environment, marking the start of intensive fossil fuel use and large-scale carbon emissions.

One of the most significant environmental consequences of the Industrial Revolution was the increase in air pollution. The burning of fossil fuels, especially coal, to power factories and steam engines, released vast amounts of pollutants into the atmosphere. Cities like London, Manchester, and Birmingham became engulfed in smog, with soot covering buildings and trees. This air pollution had severe health impacts, causing respiratory illnesses and higher death rates in areas with high coal consumption.

Waterways were also heavily polluted during the Industrial Revolution. Oil, debris, and sewage were improperly disposed of, contaminating drinking water sources. This led to waterborne diseases such as cholera, which claimed the lives of thousands in London between 1848 and 1849. The pollution of waterways disrupted fragile ecosystems and resulted in widespread losses of wildlife.

The Industrial Revolution also led to the depletion of natural resources and deforestation. The demand for resources to fuel industrialization placed immense pressure on the environment, leading to overexploitation and long-term ecological damage. Additionally, the rapid urbanization during this period resulted in overcrowding in cities, creating unhealthy living conditions with inadequate sanitation and waste management systems.

The environmental degradation caused by the Industrial Revolution had far-reaching consequences, and many of the issues persisted and grew in the subsequent decades. The depletion of the ozone layer, for example, was recognized by scientists in the 1980s, illustrating the long-term impacts of human activities during the Industrial Revolution on the planet.

Urban overcrowding

The Industrial Revolution, which began in Britain in the late 18th century, brought about tremendous changes in the country's economy, society, and urban conditions. As the country shifted from an agricultural to an industrial economy, people moved from the countryside to the cities in search of work, leading to a rapid process of urbanisation. This migration of people from rural areas to cities in search of work is a theme that is observed across Europe and America.

The rise of mills and factories drew an influx of people to cities, placing new demands on urban infrastructure. The streets of newer cities were often arranged in grid patterns that allowed indefinite expansion but took little account of human needs such as privacy and recreation. The growth of cities was not without its problems, and the living conditions for many people in urban areas were often dire. One of the primary issues associated with urbanisation was overcrowding. As people flooded into the cities, there was a shortage of housing, and many people ended up living in cramped, unsanitary conditions. Several families were often forced to share a single room, and diseases spread quickly in these crowded spaces. Cities like Manchester, Birmingham, and London experienced rapid urban growth and severe overcrowding.

The United Kingdom is a prime example of the impact of the Industrial Revolution on urban areas. In 1801, about one-fifth of the UK population lived in towns and cities with 10,000 or more inhabitants. By 1851, two-fifths were urbanised, and if smaller towns of 5,000 or more are included, more than half the population could be considered urban. By 1901, the year of Queen Victoria's death, the census recorded three-quarters of the population as urban, with two-thirds in cities of 10,000 or more and half in cities of 20,000 or more. Thus, in a single century, the UK transformed from a largely rural to a predominantly urban society.

The Industrial Revolution also fuelled the growth of cities in the United States, such as Boston, Philadelphia, New York City, and Baltimore. Advances in manufacturing in the 19th century revolutionised the American way of life. As the populations of these cities increased, they faced challenges such as housing availability, overcrowding, and the spread of infectious diseases. While most Americans lived in rural areas during the Industrial Revolution, by 1920, the US Census showed that over 50% of the population resided in urban areas.

Overcrowding in industrial cities had severe consequences for public health, leading to the spread of diseases like tuberculosis and cholera. The lack of understanding of sanitary practices in these cities resulted in sewage and waste being mixed into drinking water. For example, from 1848 to 1849, around 15,000 people died from cholera in London due to water contamination.
