Settler Colonialism

• Settled by Europeans– Neo-Europes– Similar Climates & Land

• Production of Value-Added Products

• Mostly MDCs Today

Mercantile Colonialism

• Conquer/Occupied by Europeans

• Exporting Raw Materials• LDCs Today

– Neocolonialism

MDCs vs. LDCsMDCs vs. LDCs

MDCs• Urban

• Service (Tertiary) based economy

• Has Infrastructure• Low Growth Rate• Established Middle

Class

LDCs• Urbanizing (Rural ->

Cities)• Agricultural (Primary)

Base economy• Needs infrastructure• High Growth Rate• Income Gap

Age-Sex PyramidsAge-Sex Pyramids

• Why is the earth’s population increasing the same amount each year despite a falling growth rate?– Exponential Growth (6.6 Billion)

Types of EconomiesTypes of Economies

DeforestationDeforestation

• Causes– Subsistence Farmers– Slash & Burn– Commercial Logging– Livestock Grazing– Roads (Fishbone)

• Effects– Global Carbon Cycle– Global Warming– Extinct Species (50%)– Medical losses

Free Trade vs. Fair TradeFree Trade vs. Fair Trade

Free Trade

• Removing Barriers to Trade• Barriers

– Tariffs – Taxes on Imported Goods

– Subsidies– Quotas (limits on imported

goods)– Product Bans– Environmental Protection
