How People are Affected by the Environment

1
How People are Affected by the Environment
2
Bodies of Water

• Why people settle by water
• Early civilizations
• Fresh water source
• Transportation
• Irrigation
• Cleaning
• Mills---(food, wood)
• Trade routes
• Recreation
• Modifications / changes people make to live by
  water
• Dams
• Homes on stilts/raised

3
Landforms

• People settle in flat, fertile plains where it is
  easy to build
• Fewer people live in swampy areas, mountains, or
  deserts
• Mountains and deserts often provided protection
  from invaders

4
Climate

• How people are affected or change what they do
  because of the climate
• Types of clothing
• Types of housing
• Recreation
• Agriculture (good growing season, what foods?)

5
Vegetation

• What factors affect how vegetation grows?
• Climate
• Landforms
• Soil
• Water
• How are people are affected by vegetation
• Sources of food
• Building materials
• clothing

6
Weathering

• Define weathering the wearing down of Earths
  surface by wind, ice and water
• How people are affected by weathering
• erosion
• drought-turning region into desert-desertification
  
• avalanches
• landslides/mudslides

7
Seismic Activity

• Examples of Seismic Activity
• earthquakes-tectonic plates
• Volcanoes
• How people have adapted to seismic activity
• People have changed building methods, building
  materials for homes and other buildings, and
  changed materials used to make roads and bridges
  so they are safer.

8
How People Modify the Environment

• Influenced by culture technology

9
Agriculture

• Crop cultivation- modification manipulation of
  environment- altered and cleared existing
  vegetation to grow crops

10
Urban Growth

• Concentrates 1,000s or millions in small treeless
  areas- cities replace fields and forests with
  concrete and steel.

11
Building Dams

• To drain swamps, prevent floods, store H20 and to
  generate electricity.
• Rivers carry less silt downstream.

12
Energy

• From fire to fossil fuels- dig mines and drill
  wells but more pollution.
