Local ScaleNeighbourhood

The region surrounding a person or place The more we know about our neighbourhood

changes the way we think about it Mental maps – images of places we know

Community Refers to a place where people live Can be district, town, or city Includes neighbourhood but goes beyond

School is in the neighbourhood Workplace of a family member is farther away

Area Interaction - DistantInvolves people moving from place to place

and also the exchange of information and products

Because of technology, communication of knowledge and traveling farther made easierJourney that took days to complete can now be

done in a matter of hoursDevelopments in communication has had the

effect of shrinking the distance between places.

The Global VillageAccessibility describes how easy or difficult it

is to interact with a place.Bridges make places more accessibleGlobal Village is the result of improvements to

transportation and communications systems.Worldwide interaction allows us to experience

changing trends in music, fashion, and entertainment

Makes us aware of the serious human and environmental problems the world faces

Environmental InteractionPeople interact with the environment is part

of a cause-effect relationshipClimate factors such as temperatures, length

of growing season and precipitation helps decide what crops grow in a particular areaOranges grown in Florida but not in CanadaWheat grown in Canada but not a common

crop in AfricaRelationship between climate and crops

Climate is the cause, crop is the effect

Environment Affects PeopleEnvironment influences many human activities

Ice hockey is a Canadian sport due to our cold winter temperatures

World class skiers come from mountainous regions such as Austria, Switzerland, and northern Italy

UK developed a strong navy because it is an island and water protects it from invasion

Mountains provide protection from invasion, many countries have mountain ranges as their borders

People change the EnvironmentPeople change environment to suit their

needsCreate indoor environment that allows

different activities.Built ice rinks to enjoy hockey in FloridaPeople build dams and canals to protect their

county from the North seaGreen house to grow tomatoes (cause is the

energy used to heat greenhouses and effect is the production of tomatoes)

Irrigation Project Gone WrongPeople change environment for better but find

out that their effort was negativeIrrigation is a system that takes water from

one area and uses it in other areasIrrigation project in Turkmenistan

Turkmenistan located in desert region of central Asia

Kara Kum Canal carries water from the Amu River to irrigate cotton fields

Irrigation made the dessert nation one of world’s largest producers of cotton

Irrigation Project (cont.)Flow of water from Amu River into Aral Sea

reducedCaused a drop in water level of Aral SeaEnvironmentalists fear that Aral Sea is drying upBecome too salty that majority of fish are deadCauses fish industry in region to collapse

Irrigation project created serious environmental problems

Cause-effect relationships between human actions and their environmental effects were not fully understood
