Give two challenges faced by cities with very high population density and briefly explain each

Here are two challenges faced by cities with very high population density:

1. Strain on Public Services: High population density places immense pressure on essential public services such as healthcare, education, public transport, and sanitation. This often leads to overcrowding, long waiting times, and a general decline in service quality if infrastructure and resources cannot keep pace with the rapid increase in demand.

2. Housing Shortages and Affordability Crisis: With limited land available and a large number of people needing accommodation, cities with high population density frequently experience severe housing shortages. This drives up property prices and rents, making housing unaffordable for many residents and often leading to the proliferation of informal settlements or slums, and increased homelessness.
