Over population is a condition in which a small area has to accommodate too much people. The evil effects of over population are 1. Lack of adequate housing facilities
2. Lack of adequate employment
3. Lack of adequate land for cultivation
4. Low per capita income
5. Low Gross National product.
6. Pollution of Atmosphere.
7. Lack of adequate food materials etc are the bad effects of over population.
Effects of overpopulation
The more people there are, the greater amount of food is needed. If there is not enough food to feed people in a specific place, then there is food shortage in that place. When people do not get enough food, their health is affected. People become undernourished when they do not have enough food to eat. Undernourished children are more likely to get sick. Water Shortage
When population increases, the demand for water also increases. Farmers need more water to irrigate their fields so that they can produce more crops. Factories need more water to use in manufacturing more goods. More households need more water for drinking, cooking, washing clothes, personal hygiene and many other activities. Water shortage is evident when people have to walk a long way to get water, or when they have to queue up to get it. Many people do not have access to potable water. They get their water from springs, rivers, wells and rain. The quality of water that people get may be poor.
Water shortage in a community can bring about problems related to sanitation and health. Limited Space
The population of a place increases in just a short time. However, the space in a place remains the same. When the houses in a neighborhood are overcrowded, it shows that the population in the area is too big. This is a common sight in a city. Many poor people build shanties along creeks, in dumpsites or along railroads. More than one family may share a shanty. Overpopulation in a community can limit space for housing.
