Question

Quizplus · Accepted Answer

All of these factors contributed to early industrial and slum areas being environments unfit for human habitation. Chimney soot filled the skies, causing respiratory problems and making it difficult to breathe. Streets were filled with garbage, leading to unsanitary conditions and the spread of disease. Dead animal corpses added to the unpleasant smell and attracted vermin. Lack of sewers meant that waste was often dumped directly onto the streets, again contributing to unsanitary conditions and disease. Overall, these environments were not suitable or safe for human habitation.
