Study Notes
Understanding Environmental Science
- Environmental science studies interactions between living and non-living entities, emphasizing human impacts.
- It integrates various fields such as biology, geology, and climate science while considering economic, political, and social factors.
- Ecology, a key component, focuses on relationships among organisms and their environments but is less interdisciplinary than environmental science.
- Environmentalism, a movement for protecting the environment, differs from environmental science.
Importance of Studying Environmental Science
- Understanding resource use is essential due to rising global population pressures.
- Decision-making regarding environmental impacts requires scientific principles and evidence-based arguments.
- Current environmental changes are unprecedented in human history, linking local actions to global phenomena.
- Addressing environmental sustainability necessitates collective participation and informed decision-making.
Introduction to Sustainability
- Sustainability addresses living within Earth's limits without impairing its functions.
- The report "Our Common Future" (1987) popularized sustainable development, focused on meeting present needs without compromising future generations.
- Indigenous cultures embody concepts of sustainability, highlighting long-term responsibility for resource management.
United Nations Sustainable Development Goals
- The 17 UN goals aim for true sustainability by 2030, with specific measurable targets per goal.
- Examples include "No Poverty" and environmental goals like "Climate Action."
- Social goals target education and gender equality, while economic goals focus on reduced inequalities.
Natural Capital
- Natural capital includes natural resources and ecosystem services essential for sustaining life.
- Natural resources satisfy human needs, while ecosystem services support life processes, such as water purification.
- Resources are categorized as perpetual (e.g., solar energy), nonrenewable (e.g., fossil fuels), or renewable (e.g., forests), with sustainability depending on their rate of use.
Measuring Environmental Impact
- The IPAT equation (Impact = Population x Affluence x Technology) assesses impacts of human activities.
- Developed nations tend to have higher per capita impacts due to wealth and technology compared to developing countries.
- The ecological footprint measures land and water needed to support lifestyles, with the average American footprint significantly exceeding global averages.
Causes of Environmental Problems
- Major environmental issues stem from four fundamental causes: unsustainable resource use, negative externalities, economic inequality, and unsustainable population growth.
- Unsustainable Resource Use: Earth Overshoot Day signals when consumption surpasses regeneration capacity, indicating rapid resource depletion.
- Negative Externalities: Market prices often exclude environmental harm costs, leading to societal and ecological consequences.
- Economic Inequality: Wealth gaps impact consumption patterns, influencing ecological footprints; wealth may lead to higher consumption or enable positive environmental actions.
- Unsustainable Population Growth: World population growth presents challenges for resource sustainability, with projections indicating stabilization post-2050.
Addressing Environmental Challenges
- Solutions require balancing population growth, consumption patterns, and resource management.
- Strategies include promoting family planning, women's opportunities, and efficient resource use to minimize ecological impacts.
- The IPAT model emphasizes the need to manage population and consumption to achieve sustainable development outcomes.
