Pollution in cities during the late 1800s was caused in part by horses, coal, and inadequate sewer systems.
a. true
b. false

True. In the 1800s, burning coal was the main method of heating homes, water and cooking food. Burning coal gave off a lot of pollution, including gases like sulfur dioxide and carbon dioxide. In Britain, manufactured gas also started at this time, and the waste was dumped in rivers and sewers which then became polluted.
