Step-by-step explanation:
Yes, I agree that many houses are poorly constructed, unsanitary, old, run-down, and overcrowded. Throughout history, there have been numerous examples of housing conditions that have posed serious health and safety risks for residents.
For instance, in the late 19th and early 20th centuries, cities like New York were plagued by overcrowded tenements and slums, where lack of sanitation, ventilation, and fire protection led to the rapid spread of diseases. Similarly, in present times, many cities in Africa have self-constructed slums and squatter settlements that lack basic public services and contribute to health problems and environmental degradation.
