5.1 Global Maritime Empires and Resource Extraction

European maritime empires established global trade networks, connecting continents and facilitating exchange. This expansion had significant environmental impacts, including deforestation, soil degradation, and the spread of non-native species and diseases.

Resource extraction in colonized regions led to depletion of natural resources and disruption of local ecosystems. Technological advancements in navigation, shipbuilding, and agriculture intensified resource exploitation and environmental degradation in colonized areas.

1 of 3

• European maritime empires (British, Dutch, Portuguese) established vast global trade networks connecting Europe, Africa, Asia, and the Americas facilitating the exchange of goods, people, and ideas across continents
• Deforestation increased due to high demand for timber for shipbuilding and other purposes
• Intensive agricultural practices to meet growing demand for cash crops caused soil erosion and degradation
• Introduction of non-native species (intentionally and unintentionally) altered ecosystems
• Spread of diseases affected both human populations and wildlife
• Shipping and transportation led to increased carbon emissions

Resource extraction in colonized regions

• European powers exploited natural resources in colonized regions
  • Extracted precious metals (gold, silver) from the Americas
  • Obtained spices, textiles, and other valuable commodities from Asia
  • Procured timber, rubber, and other raw materials from Africa
• Resource extraction led to:
  1. Depletion of non-renewable resources
  2. Disruption of local ecosystems and biodiversity loss
  3. Displacement of indigenous populations and loss of traditional land-use practices
  4. Economic dependency of colonized regions on European powers
  5. Social and political instability resulting from unequal power dynamics

Technology and Ecological Effects

Technology's role in global trade

• Advancements in navigation and shipbuilding technologies
  • Improved navigational instruments (astrolabe, sextant) enabled more accurate long-distance travel
  • Development of sturdier, faster ships (caravels, galleons) allowed for longer voyages and increased cargo capacity
• Innovations in mining and agricultural technologies
  • New mining techniques (hydraulic mining, amalgamation process) increased efficiency of resource extraction
  • Improved agricultural tools and practices (plows, crop rotation) boosted production of cash crops (sugarcane, cotton)
• Technology impacted the scale and intensity of resource exploitation by:
  • Enabling European powers to access and exploit resources from distant regions more effectively
  • Contributing to rapid depletion of natural resources and environmental degradation in colonized areas (deforestation, soil degradation)

Ecological effects of Columbian Exchange

• Columbian Exchange: widespread transfer of plants, animals, diseases, and ideas between the Americas and the Old World (Europe, Africa, Asia) following Columbus's voyages
• Ecological effects on the Americas:
  1. Introduction of Old World domesticated animals (horses, cattle, pigs, sheep) altered landscapes and ecosystems
  2. Spread of Old World diseases (smallpox, measles, influenza) decimated indigenous populations, leading to abandonment of agricultural lands and regrowth of forests
  3. Adoption of Old World crops (wheat, barley, sugarcane) changed agricultural practices and land use patterns
• Ecological effects on the Old World:
  1. Introduction of New World crops (maize, potatoes, tomatoes) transformed agriculture and diets
  2. New World plants (cocoa, vanilla) became integral to Old World ecosystems and economies
  3. Transfer of New World species (tobacco) led to development of new industries and associated environmental impacts from cultivation
