AIR POLLUTION

Air pollution is a threat that has plagued humanity for millennia, though our understanding and ability to combat it have evolved significantly. This article delves into the history of air pollution, exploring its causes from ancient times to the present day.

Early Traces of Air Pollution

The story of air pollution stretches back as far as human civilization itself. Even in prehistoric times, burning wood for cooking and warmth released smoke and soot into the air, impacting our ancestors' health. Evidence of this can be found in the blackened lung tissue discovered in mummies from various cultures.

The Industrial Revolution and the Rise of Coal

The Industrial Revolution ushered in a new era of air pollution. Coal became the dominant fuel source for factories, spewing massive amounts of pollutants like sulfur dioxide and particulate matter into the atmosphere. These emissions led to the infamous "smog" events that choked cities like London and New York in the 19th and early 20th centuries. These events caused widespread respiratory problems and even death.

The Age of Automobiles and a Growing Threat

The 20th century saw the rise of the automobile, introducing a new source of air pollution. Vehicles released harmful pollutants like carbon monoxide, nitrogen oxides, and hydrocarbons. As cities became more car-dependent, air quality deteriorated further.

The Fight for Clean Air

The health impacts of air pollution became increasingly evident in the 20th century. This led to the rise of environmental movements and stricter regulations. The Clean Air Act of 1970 in the United States stands as a landmark achievement, setting air quality standards and empowering the Environmental Protection Agency (EPA) to regulate emissions.

Causes of Air Pollution Today

While significant progress has been made, air pollution remains a major global challenge. Some of the key causes today include:

• Fossil fuel combustion: Burning coal, oil, and natural gas for energy production continues to be a major contributor.
• Industrial processes: Factories and industrial facilities release various pollutants into the air.
• Transportation: Cars, trucks, and airplanes are significant sources of air pollution.
• Agriculture: Deforestation and agricultural practices can contribute to air pollution.

AIM FOR CLEAN AIR

Instead of using cars every day, we can use more public transport such as MRT or bus, ride a bike, or walk whenever possible. Rather than burning trash, we can recycle and reuse.

The fight for clean air is ongoing. The development of renewable energy sources, stricter regulations on emissions, and advancements in clean technology offer hope for a future with cleaner air.

By understanding the history and causes of air pollution, we can work towards a healthier planet for ourselves and future generations.
