How to live comfortable in an over populated environment?
Over populated areas lead to scarcity of resources at different levels if not dealt properly. There is fight and increase in prices of land, food and water. Also, healthcare and employment is difficult to serve as demand is high and capital can be less. But there can be some positive outcomes for overpopulated areas like diversity in culture and if we consider a marketplace, more players lead to more competition which leads to competitive pricing and eventually benefits the people.
There are advantage and disadvantage of over population, it creates scarcity yes but it also creates opportunity for most people as you can sell any kinds of staff, good and services as there's a lot demand, just like here in our country wherein it is over populated but created a lot of demand.
