Key Concepts in Environmental Science and Sustainability

ch.2

Rachel Carson and Environmental Sustainability

  • Publication of "Silent Spring" in 1962 questioned pesticide use in agriculture.

  • Highlights trade-offs between short and long-term environmental health.

Sustainable Development

  • Defined as economic growth meeting current needs without compromising future generations.

  • High resource consumption in developed nations is unsustainable globally.

Sustainable Consumption

  • Balance needed between quality of life and resource use.

  • Affluent lifestyles result in higher pollution and resource consumption.

  • Global poverty must be addressed; rich countries need to reduce consumption.

Voluntary Simplicity

  • A lifestyle approach focusing on quality of life rather than material goods.

  • Promotes sustainable practices like car-sharing and public transport.

Environmental Ethics

  • Focuses on human values, morality, and responsibility toward the environment.

  • Examines the rights of current and future generations.

Worldviews on Nature

  • Western worldview: Human superiority leads to resource exploitation.

  • Deep ecology: Emphasizes equality among all living beings and harmony with nature.

Environmental Justice

  • Right to protection from environmental hazards for all citizens.

  • Links social justice issues with environmental concerns.

Responding to Global Inequality

  • Disparity in resource distribution (e.g., US: 5% population controls 25% economy).

  • Need for universal education and uplifting the global poor while ensuring sustainability.

Protecting Natural Resources

  • Importance of preserving ecosystems and utilizing resources sustainably.

  • Biodiversity loss impacts health and resources.

Addressing Food Insecurity

  • 800 million people lack adequate food; agriculture improvement is crucial for sustainability.

Mitigating Climate Change

  • Climate change driven by increased greenhouse gas emissions.

  • Requires comprehensive plans to reduce emissions and enhance energy efficiency.

Designing Sustainable Cities

  • Over 50% of the global population in cities; urban planning must prioritize livability.

  • Shift from car-centric to people-centric designs to improve quality of life.

Case Study: Loess Plateau, China

  • Historical deforestation led to desertification; rehabilitation efforts are ongoing to restore the ecosystem.
