Uneven distribution has costs
- Because people are spread unevenly, different places face very different pressures.
- Crowded regions strain resources; empty regions struggle to provide services.
- Population distribution shapes politics, economics, and the environment.
Pressure in crowded places
- Dense areas strain housing, water, jobs, and services.
- They can suffer pollution, congestion, and rising land prices.
- But density also concentrates workers, markets, and ideas.
A typical problem of a very densely populated area is...
Crowding strains housing, water, jobs, and services.
Select all problems linked to high density.
Congestion, housing, and pollution come from crowding; distant hospitals come from low density.
Problems in empty places
- Sparsely populated areas struggle to fund roads, schools, and hospitals.
- Few taxpayers must cover services spread over a wide area.
- Carrying capacity 承载力 is the number of people an area can sustainably support.
Crowded or empty problem?
Sort each consequence by whether it comes from high or low density.
Sparsely populated areas can struggle to fund services because few taxpayers cover a wide area.
Low density spreads few taxpayers thinly, making roads, schools, and hospitals costly.
The number of people an area can sustainably support is its carrying ____.
Carrying capacity is the sustainable population an area can support.
Match each consequence to its density.
Congestion = crowded; distant underfunded services = empty; carrying capacity = the sustainable limit.
"Crowded = bad, empty = good" is too simple. Dense cities are also engines of jobs and innovation; empty regions can be rich in resources but poor in services. Judge the consequences by the local context, not by density alone.
A megacity may have millions crammed into slums with too little clean water (a consequence of high density). A remote rural county may have no hospital within 100 km because too few taxpayers live there (a consequence of low density). Same country, opposite problems.
Uneven population distribution creates opposite problems: crowded areas strain housing, water, and services (but concentrate opportunity); empty areas struggle to fund services over a wide area. Carrying capacity is how many people a place can sustainably support.
