The Dark History Of Pollution: When Did It Begin?

Pollution has been a problem since the emergence of our earliest ancestors, with increasing human populations leading to more bacteria and disease. During the Middle Ages, diseases such as cholera and typhoid fever spread across Europe due to unsanitary conditions. The Industrial Revolution, which began in the late 18th and early 19th centuries, marked a significant increase in pollution levels, particularly in Europe and North America. The burning of coal and the use of factories led to smog and soot, causing serious health issues in urban areas. While pollution has been an issue for centuries, the term pollution itself gained traction in the 19th century, with episodes of smog in cities like New York and London resulting in numerous deaths. Today, pollution remains a pressing global challenge, with air pollution being the leading cause of environment-related deaths, and water pollution leaving over a billion people without access to safe drinking water.

Pollution has existed since the appearance of our earliest ancestors

Pollution has been a problem since the emergence of our earliest ancestors. As human populations grew, so did the prevalence of bacteria and disease. During the Middle Ages, for instance, Europe was ravaged by cholera and typhoid fever outbreaks, which were caused by unsanitary conditions due to human and animal waste.

The establishment of permanent settlements by large numbers of people also contributed to the issue. Ancient cities were often polluted by human waste and debris. Around 1000 CE, the use of coal for fuel caused significant air pollution, and the conversion of coal to coke for iron smelting further exacerbated the problem.

The Industrial Revolution in the 18th and 19th centuries brought large-scale coal use, leading to smog and soot that had severe health consequences for residents of growing urban centres. The burning of coal in factories and homes, along with automobile emissions, industrial processes, and mass deforestation, have all contributed to air pollution.

In the 19th century, episodes of "smog" in cities like New York and London resulted in numerous deaths. By the middle of the 20th century, the effects of the Industrial Revolution were being felt globally, with the release of pollutants into the environment causing climate change and global warming. The leading cause of air pollution in the US today is motor vehicles, which were first mass-produced in the country by Henry Ford in the early 20th century.

Water pollution has also been an issue for centuries, with humans unknowingly contaminating drinking water sources with raw sewage, leading to diseases. The Industrial Revolution intensified water pollution as factories began releasing pollutants directly into rivers and streams. In 1897, a report detailed the severe industrial contamination of the Tawe River in Wales, and similar pollution was observed in the US Northeast.

While pollution has ancient origins, the term "Anthropocene" acknowledges the unprecedented impact of human activities on the Earth during the industrial era, particularly with the advent of nuclear technology in 1945.

The Industrial Revolution's impact on pollution

Pollution has been a problem since the earliest ancestors of humans appeared. As populations grew, the risk of disease increased, and during the Middle Ages, Europe suffered outbreaks of diseases such as cholera and typhoid fever, caused by unsanitary conditions.

However, the Industrial Revolution, which began in Britain in the late 18th to early 19th centuries, marked a significant intensification of pollution. The First Industrial Revolution introduced mass coal burning, which powered the newly developed steam engine. This led to an increase in air pollution, particularly in industrial cities, causing thick smog and soot which had serious health impacts on residents. The burning of coal also led to an increase in carbon emissions and harmful environmental pollution.

The Second Industrial Revolution, or Technological Revolution, introduced electricity, steel production, and the internal combustion engine. This phase drove mass production and the growth of heavy industries across Europe and North America, leading to exponential increases in energy consumption and resource extraction. The environmental consequences were severe, with rapid industrial growth outpacing the ability to manage waste and emissions, resulting in long-term damage to the environment and public well-being.

The Industrial Revolution also contributed to water pollution, as factories began releasing pollutants directly into rivers and streams. In the United States, industrial chemicals and wastes contaminated waters in the Northeast, and the Cuyahoga River in Ohio became a symbol of how industrial pollution was destroying natural resources when it caught fire in 1969.

The impact of the Industrial Revolution on pollution was complex and far-reaching, and it is still felt today. While there have been improvements in human rights and labor conditions since, there is still much work to be done to address the negative cycles and ethical implications arising from this period.

Water pollution in the US

In the mid-19th century, cities like Chicago began to address water pollution by implementing sewage systems to treat wastewater. However, as industrialization expanded in the late 19th century, water pollution became more severe. Industrial wastes contributed toxic pollutants and chemicals, which had detrimental effects on ecosystems and public health.

The post-World War II era saw a rapid increase in industrialization and population growth, which further exacerbated water pollution concerns. Outbreaks of waterborne diseases, degradation of fishing and recreational waters, and the direct dumping of industrial waste into water sources prompted a new appraisal of water pollution control. The Federal Water Pollution Control Act of 1948 was the first major US law to address water pollution, but it wasn't until the 1970s that control of major pollution sources such as domestic sewage, industry, and agriculture was effectively regulated.

The Clean Water Act (CWA) of 1972 played a pivotal role in reducing water pollution levels in US waterways. This legislation provided funding for improving sewage treatment plants and set limits on the discharge of pollutants into water bodies. While the CWA brought about significant improvements, water pollution remains a pressing issue in the US. Even in the 21st century, many water bodies continue to violate federal water quality standards, and the presence of "forever chemicals" like PFAS in drinking water poses a significant health risk to the population.

To address the complex and evolving nature of water pollution, various solutions are being implemented. These include municipal wastewater treatment, agricultural and industrial wastewater treatment, erosion and sediment control, and the control of urban runoff. Additionally, organizations like the NEIWPCC are actively working to protect water quality through initiatives such as the Lake Champlain Basin Program and the Youth and the Environment Program. Despite these efforts, water pollution in the US still faces significant challenges, and continuous monitoring and adaptation are necessary to ensure the sustainability of this precious resource.

Air pollution in the US

Air pollution has been a problem for centuries, but it became a much more significant issue with the onset of the Industrial Revolution in the 1800s. The transition to mechanised factory systems, chemical manufacturing, iron production, and increased use of steam power led to unprecedented levels of air pollution. The burning of coal in factories and households, as well as the rise in coal-powered automobiles, contributed to the degradation of air quality.

In the US, the problem of air pollution was particularly acute in industrial cities like Pittsburgh. As early as 1898, steel tycoon Andrew Carnegie acknowledged that smoke was driving people away from Pittsburgh. After World War II, the US experienced rapid population growth, urbanisation, and industrialisation, which further exacerbated the issue. By the end of the 1960s, there were 100 million vehicles on American roads, and the country was facing the harsh consequences of its industrial growth.

The situation in Donora, Pennsylvania, in 1948 and 1960, where air pollution killed 20 people and made 40% of the town's inhabitants ill, reflected a growing trend. Similar crises were widely publicised, and people began to take notice and demand action. Scientists started investigating the link between air pollution and health, and states began passing legislation to reduce air pollution.

In 1970, Congress passed the Clean Air Act, which allowed the newly created US Environmental Protection Agency (EPA) to set national air quality standards. The EPA targeted human-made polluters, such as factories and cars, and invested in the enforcement of emission-lowering technology, including catalytic converters. As a result, emissions of nitrogen oxide, non-methane volatile organic compounds, and sulfur dioxide have significantly declined since 1970.

Despite these efforts, air pollution remains a severe problem in the US. Six out of ten Americans live in areas where air pollution reaches unhealthy levels. The average annual acreage burned by wildfires in the US has more than doubled over the past few decades, contributing to the worsening threat of particulate matter in the air. Addressing air pollution is crucial to preventing its devastating impact on public health and the environment.

Pollution in the 21st century

Pollution has been a problem since the earliest human ancestors. However, the 21st century has seen the emergence of new environmental issues that require urgent action. The leading cause of air pollution in the US is motor vehicles, which were first mass-produced in the US by Henry Ford in the early 20th century. Auto emissions also increase the amount of greenhouse gases in the atmosphere, contributing to global warming.

In the 21st century, carbon dioxide and other air pollutants, water pollutants, and land pollutants are the most common types of substances contaminating the Earth. Carbon dioxide exists naturally in the environment, but human activity since the Industrial Revolution has led to an excessive amount of carbon dioxide in the atmosphere, causing the Earth to warm unnaturally—a phenomenon known as global warming. Ozone, particulate matter, carbon monoxide, nitrogen dioxide, sulfur dioxide, and lead are common air pollutants. Carbon monoxide, sulfur dioxide, and lead are usually released directly into the atmosphere from industrial activity.

Water pollution has also intensified with the advent of the Industrial Revolution, as factories began releasing pollutants directly into rivers and streams. Dirt, bacteria, and nutrients are the three most common categories of pollutants in the Earth's water. Dirt is carried into rivers and streams by rainwater, clogging the gills of fish, killing fish eggs, and interfering with photosynthesis. Deforestation and mining are the two most common sources of dirt. Sewage overflow and runoff from animal waste are the two most common sources of bacterial water pollution, causing waterborne diseases such as cholera, typhoid fever, and amebiasis.

Land pollution is often caused by improperly disposed-of trash, which can seep into the ground and contaminate water tables. Noise pollution is another issue, with the 20th century being the noisiest century in history due to the spread of transportation noise. The 21st century is likely to see new technologies impacting the soundscape, and the response of governments will be crucial in determining whether it becomes the loudest century.
