Overpopulation puts a tremendous strain on resources. If too many people live in a place with too few resources (food, water, etc.), there are many negative effects. The biggest concern is access to water. A lack of fresh water can lead to unsanitary living conditions, which can cause disease, infection and increased child and infant mortality.
