🌼Environmental History Unit 8 – Environmental History: Globalization & Pollution

Key Concepts & Definitions

• Globalization: Increased interconnectedness and interdependence of world economies, cultures, and populations
  • Involves cross-border trade, investment, and cultural exchange
  • Facilitated by advancements in transportation and communication technologies
• Anthropocene: Proposed geological epoch marked by significant human impact on Earth's geology and ecosystems
• Pollution: Introduction of harmful substances or energy into the environment, causing adverse effects
  • Can affect air, water, soil, and living organisms
  • Sources include industrial emissions, agricultural runoff, and waste disposal
• Greenhouse gases: Atmospheric gases that absorb and emit infrared radiation, contributing to the greenhouse effect
  • Examples include carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O)
• Carbon footprint: Total amount of greenhouse gases generated by an individual, organization, or product
• Environmental degradation: Deterioration of the environment through depletion of resources and destruction of ecosystems
• Sustainability: Meeting present needs without compromising the ability of future generations to meet their needs

Historical Context

• Industrial Revolution (late 18th to 19th century) marked a shift from manual labor to mechanized manufacturing
  • Led to increased production, urbanization, and resource exploitation
  • Resulted in significant environmental impacts, such as air and water pollution
• European colonialism and imperialism (15th to 20th century) facilitated the global spread of industrialization and resource extraction
  • Exploitation of natural resources in colonized regions
  • Introduction of new crops and agricultural practices, often leading to environmental degradation

  • Increased demand for resources and energy
  • Development of synthetic materials and chemicals with long-lasting environmental impacts
• Green Revolution (1950s to 1960s) aimed to increase agricultural productivity through the use of high-yielding crop varieties, fertilizers, and pesticides
  • Contributed to increased food production but also led to environmental issues such as soil degradation and water pollution
• Rise of consumerism and globalized trade in the 20th century
  • Increased demand for goods and resources, leading to expanded production and transportation networks
