Changing Population Trends


  • A rapidly growing population uses resources at an increased rate and can overwhelm the infrastructure of a community.

  • Infrastructure: The basic facilities and services that support a community, such as schools and hospitals.


Problems of Rapid Growth

  • People cannot live without:

    • Clean Water

    • Fuel

    • Land that can be farmed for food


A Shortage of Firewood

  • In many of the poorest countries, wood is the main fuel source.

  • Stable population  Deadwood is used

  • High pop growth  Healthy, living trees are cut down


What is Fuel used for?

  • A supply of fuel ensures that a person:

    • 1) Can boil water.

      • Public, available water is dirty and contains water-borne pathogens

    • 2) Cook food

  • Without enough fuelwood, many people suffer from disease and malnutrition.


Unsafe Water!!

  • In places that lack infrastructure, the local water supply may be used for sewage disposal (in addition to drinking)!


Dirty, Nasty Water

  • The water supply, becomes a breeding ground for organisms that cause diseases such as:

    • Dysentery

    • Typhoid

    • Cholera


Impacts on Land

  • Growing populations may have a shortage of arable land, which is land that can be used to grow crops.


Urbanization

  • Much of the world’s population is undergoing urbanization, the movement of people from rural areas to cities.


Suburban Sprawl

  • Leads to:

    • Traffic Jams

    • Inadequate infrastructure

    • Reduction of land for

      • farming

      • Wildlife habitat

    • Housing within cities becomes more costly
