what are the social cost (how can it affect the way people live) of overpopulation?

Question

are there any advantage?

Answer 1

Poverty, disease, crime, pollution, overcrowding, traffic, and war. Every measure of pollution and other human social ailments can be multiplied by the population increase factor. This the most important reason to prevent millions of illegal alien squatters from entering and staying in this country. If unchecked, they will turn the US into Tijuana. Believe me, I worked in East LA for 30 years.
