Cholera, Sewage, and Public Health

The video explores the Great Stink of 1858 in London, caused by sewage pollution in the Thames. It highlights the role of Dr. John Snow in identifying cholera's link to contaminated water and the eventual government response led by Joseph Bazalgette, who designed a sewer system that improved public health and is still in use today.
