Pollution has been a problem since ancient times, but it became a more pressing issue with the establishment of permanent settlements and the use of coal for fuel around 1000 CE. The Industrial Revolution, which began in the early 1800s, further exacerbated pollution levels, particularly in industrialized cities in Europe and the United States. The first major laws to address pollution were enacted in the mid-to-late 1900s, such as the Federal Water Pollution Control Act of 1948 in the US and the Clean Air Act of 1956 in the UK, which aimed to tackle air pollution from industrial activities.

Pollution has been addressed in some form since prehistoric times
By the 1800s, the link between unsanitary living conditions, water contamination, and disease epidemics was established. This prompted major cities to take measures to control waste and garbage. Chicago built the first major sewage system in the United States in the mid-1850s to treat wastewater, and soon other U.S. cities followed suit.
The Industrial Revolution, which began around 1820-1840, brought about new manufacturing processes and a rise in mechanized factories, chemical manufacturing, and iron production. This led to increased consumption of natural resources and coal, contributing to unprecedented levels of air pollution. The expansion of factories and the increased use of coal for combustion and heating in private households further exacerbated the problem.
In 1881, Chicago and Cincinnati became the first two American cities to enact laws for cleaner air. In 1897, a report to the Royal Commission on River Pollution detailed the gross industrial contamination of the Tawe River in Wales, highlighting the severity of water pollution.
The 20th century saw a growing awareness of pollution and its impacts, with the Clean Air Act of 1956 in the UK and the Air Pollution Control Act of 1955 in the US being significant milestones in addressing air pollution. These were followed by other important legislation, such as the Clean Water Act and the National Environmental Policy Act, which aimed to tackle water pollution and protect the environment.

The Industrial Revolution caused unprecedented air pollution
The use of the word "pollution" generally implies that contaminants have an anthropogenic source, or a source created by human activities. Pollution has been present since ancient times, when permanent settlements led to the accumulation of waste and debris. However, the Industrial Revolution, which took place between the eighteenth and nineteenth centuries, marked a significant turning point, causing unprecedented air pollution.
The Industrial Revolution was a period of rapid economic growth and technological advancements. It introduced electricity, steel production, and the internal combustion engine, driving mass production and the expansion of heavy industries across Europe and North America. Countries like the UK, Germany, and France rapidly industrialized, leading to exponential increases in energy consumption and resource extraction.
A key aspect of the Industrial Revolution was the shift to manufacturing based on heavy industrial machinery, powered primarily by fossil fuels such as coal. This transition improved efficiencies and output but had detrimental environmental consequences. The combustion of coal released large quantities of carbon emissions, pollutants, particulate matter, and toxicants into the atmosphere. As factories proliferated, their chimneys released vast amounts of smoke and soot, darkening skies and shrouding urban landscapes in smog.
The unchecked use of fossil fuels and the rapid expansion of industrialization outpaced the ability to manage waste and emissions. This led to long-term environmental degradation, natural resource depletion, and a continuous rise in greenhouse gases. The air pollution resulting from the Industrial Revolution had severe health impacts on workers and residents, with poor air quality contributing to serious public health issues and increasing the risks of premature death.
The Clean Air Act, passed in the mid-20th century, was a crucial step in addressing air pollution arising from industrial activities. It led to significant reductions in emissions in urban areas and the closure of polluting industrial infrastructure. While legislation has since been strengthened, the environmental impact of the Industrial Revolution continues to be felt today, with global challenges arising from high emissions and resource exploitation.

The Clean Air Act of 1956 was a major modern response
The Clean Air Act of 1956 introduced several measures to reduce air pollution. It allowed for the establishment of ""smoke control areas" in towns and cities, where only smokeless fuels could be burned. This shift towards cleaner coals, electricity, and gas reduced smoke pollution and sulphur dioxide emissions from household fires. The Act also included provisions to prevent the emission of dark smoke from chimneys and required new furnaces to be smokeless. Local planning authorities were empowered to mandate higher and more effective chimneys on buildings, and the minimisation of emitted grit and dust.
The 1956 Act was significant as it addressed the flaws in previous anti-smoke legislation in Britain, which had offered limited protection to urban dwellers and the environment. Earlier smoke control laws, including the Public Health Act of 1875 and the Public Health (Smoke Abatement) Act of 1926, contained ambiguous clauses and imposed insignificant fines, effectively providing industrialists with little incentive to reduce pollution. The Clean Air Act of 1956, however, had important implications for the debate around public regulation, public health, and the role of government intervention.
The Act's impact extended beyond air quality improvements. By prohibiting certain practices in private households, it sparked discussions about the legitimate scope of government intervention in protecting public health and regulating environmental pollution. This Act was a crucial step in recognising the link between air pollution and public health, a relationship that was well understood by the late 19th century but had not been effectively addressed through public health measures. The Clean Air Act of 1956 set a precedent for future environmental legislation and informed subsequent Clean Air Acts in 1968 and 1990, which further strengthened protections against air pollution.

International agreements addressed global pollution in the 1980s
The 1980s witnessed a growing global awareness of pollution and its detrimental effects, prompting international agreements to address this pressing issue. One notable agreement during this decade was the Montreal Protocol, finalised in 1987. This protocol addressed the issue of ozone depletion, a global concern due to its impact on the Earth's protective ozone layer. The agreement aimed to phase out the production and consumption of ozone-depleting substances (ODS) commonly found in products such as refrigerators, air conditioners, fire extinguishers, and aerosols. The Montreal Protocol was a groundbreaking achievement, receiving universal ratification from all countries.
Another significant agreement during the 1980s was the UNECE Convention on Long-range Transboundary Air Pollution, which entered into force in 1983. This convention was signed by 32 countries in the pan-European region and established the foundation for international cooperation in mitigating air pollution. It created an institutional framework that united science and policy, significantly influencing the development of international environmental law. The convention has since expanded its scope to include additional pollutants, such as ground-level ozone, persistent organic pollutants, heavy metals, and particulate matter.
While the aforementioned agreements primarily focused on air pollution and ozone depletion, the 1980s also saw the emergence of discussions and efforts to address global warming and greenhouse gas emissions. The Intergovernmental Panel on Climate Change (IPCC) was formed in 1988 by the World Meteorological Organization (WMO) and the United Nations Environment Program (UNEP) to address the growing concern of anthropogenic global warming. The IPCC played a crucial role in bringing attention to the impact of human activities, particularly the burning of fossil fuels, on the planet's temperature.
Overall, the 1980s marked a significant period in the global effort to address pollution and its impact on the environment and human health. These international agreements laid the groundwork for further action and cooperation in mitigating the harmful effects of pollution and protecting our planet.

Pollution awareness increased in the US in the 1950s-1970s
The 1950s marked the beginning of an increased awareness of pollution in the US. The 1948 Donora incident, in which 20 people died and over 7,000 others were hospitalised after a smog episode, led to the creation of the Air Pollution Control Act of 1955. This was the first federal attempt to control air pollution in the US.
In the 1950s, Los Angeles County was home to approximately 4 million cars. As Los Angeles is in a basin, automotive emissions hung in the air and smog became a part of daily life. A group of Beverly Hills housewives formed Stamp Out Smog in the 1950s and drew attention to the city's problems through demonstrations.
In the 1960s, there was a turning point in popular awareness about environmental problems in the US. The modern environmental movement that emerged during this time focused on human industry as the cause of pollution and advocated for federal and state regulation, along with personal actions, to control pollution. The 1969 Cuyahoga River fire, which was caused by debris and oil igniting on the water's surface, further highlighted the issue of pollution in the US.
The 1960s also saw a rise in environmental activism, with local politicians, residents, and environmental organizations demanding action to address the smog crisis, chemical toxins, and pollutants in the drinking supply. In January 1969, a Union Oil drilling platform exploded off the coast of Santa Barbara, California, dumping around 100,000 barrels of crude oil into the ocean and causing a catastrophic ecological impact. This event outraged public opinion and inspired politicians at all levels to take action.
By the 1970s, the Environmental Protection Agency (EPA) had been established in the US and was working to protect Americans and the environment through various initiatives. The EPA enforced the Clean Air Act to protect air quality and the Clean Water Act to clean up polluted rivers and ensure safe drinking water. The EPA also worked to prevent hazardous chemical spills and waste dumps, and to reduce high noise exposure from airplanes.
