Notably, King Edward I of England issued a proclamation in 1272 banning the burning of sea-coal in London after its smoke became a pervasive issue, highlighting early recognition of pollution hazards.
London's Water Crisis and Sewerage System Development
London faced a significant water quality crisis in 1858, famously known as the Great Stink, along the Thames River. This environmental catastrophe spurred the construction of the London sewerage system, a pioneering effort to mitigate pollution. The surge in population outpaced the capacity of neighborhoods to manage waste, leading to heightened demand for sewer systems and clean water.
Sanitary Reforms and Urban Development
The 19th century witnessed a paradigm shift in sanitary conditions, notably illustrated by Berlin's transformation. Before the late 1870s, Berlin grappled with dire sanitation issues, characterized by open gutters collecting waste-water and primitive public facilities. August Bebel vividly recounts the appalling conditions before the city's modern sewer system was established, emphasizing the transition from barbarism to civilization.
