  1. Changing Population Trends

  2. 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.

  3. Problems of Rapid Growth • People cannot live without: • Clean Water • Fuel • Land that can be farmed for food

  4. 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

  5. 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.

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

  7. Dirty, Nasty Water • The water supply, becomes a breeding ground for organisms that cause diseases such as: • Dysentery • Typhoid • Cholera

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

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

  10. Suburban Sprawl • Leads to: • Traffic Jams • Inadequate infrastructure • Reduction of land for • farming • Wildlife habitat • Housing within cities becomes more costly

  11. Oh the Possibilities
