Water Pollution and Disease in History

The video explores the evolution of water quality understanding from the Middle Ages to the 19th century. Initially, people were unaware of the health risks posed by contaminated water. The invention of the microscope by Anthony van Levanhoek in the 17th century allowed for the discovery of bacteria, although its significance was not yet understood. By the late 1800s, waterborne diseases like cholera were rampant in European cities, notably in Hamburg, Germany. The city's poor sanitation and river pollution exacerbated the problem. A renowned bacteriologist identified water as the key to controlling outbreaks, leading to the installation of filtration systems.
