Environmental Sustainability
Environmental Sustainability
- Sustainability: A multi-faceted concept involving responsible use of resources to meet human needs while preserving the environment for future generations.
- What does sustainability mean to you?
- Personal examples of sustainable practices.
Key Definitions
- Ecology: The study of relationships between living organisms and their environment.
- Environmentalism: A social movement aimed at protecting life support systems for all species.
Sustainable Solutions
- Sustainable practices include:
- Reduce: Decreasing consumption.
- Reuse: Utilizing products multiple times before discarding.
- Recycle: Processing materials to make new products.
- Sustainable solutions can save money and promote eco-friendly energy, such as:
- Solar energy
- Wind energy
- Hybrid vehicles
Key Components of Sustainability
- Life depends on:
- Natural Capital: The world's stocks of natural assets including geology, soil, air, water, and all living things.
- Natural Resources: Materials and energy necessary for human life.
- Natural Services: Ecosystem processes that support life such as air and water purification.
- Many human activities contribute to the degradation of natural capital.
- Local and personal initiatives are critical beginnings for sustainability efforts.
Value of Natural Capital
- Understanding components of natural capital:
- Natural resources and natural services combined are essential for human survival.
- For example, solar energy, clean air, climate regulation, biodiversity, and nutrient recycling are all valued aspects of natural capital.
Types of Resources
- Renewable Resources: Energy sources such as solar that are continuously replenished.
- Nonrenewable Resources: Fixed quantities like fossil fuels, minerals that cannot be replenished in a short time frame.
- Sustainable Yield: The maximum rate at which resources can be used indefinitely without depletion.
- Ecological Footprint: The biologically productive land and water required to support a person.
- Defined in terms:
- Per Capita Ecological Footprint: Average footprint of an individual in a specific area.
- Ecological Deficit: When consumption exceeds the biological regeneration capacity.
Reasons for Environmental Problems
- Major drivers include:
- Population growth and its exponential increase.
- Unsustainable resource use and pollution.
- Poverty impacting environmental choices.
- Exclusion of environmental costs from market prices.
Impacts of Affluence and Poverty
- Affluence can lead to:
- High consumption and waste levels.
- Positive impacts such as funding for technology and environmental improvements.
- Poverty results in:
- Short-term survival actions that harm the environment.
- Increased health issues and lack of access to clean resources.
Addressing Environmental Costs
- Prices of goods often do not reflect damaging environmental impacts.
- Potential solutions include:
- Shift subsidies to favor the environment.
- Tax pollution while reducing income tax.
Differing Perspectives on Environmental Issues
- Individual views influence environmental ethics:
- Planetary Management: Humans are separate from nature and in control of it.
- Stewardship: Humans have an ethical responsibility to care for the environment.
- Environmental Wisdom: Acknowledges that humans are dependent on nature, which should benefit all species.
Characteristics of an Environmentally Sustainable Society
- Such societies protect natural capital and operate within its means:
- Reliance on renewable energy sources.
- Resource protection to maintain biodiversity and natural processes.
- Commitment to responsible resource use and minimizing pollution.
Principles for Sustainability
- Utilize natural cycles efficiently by:
- Reducing waste and pollution.
- Not overloading natural systems with harmful chemicals.
- Ensuring natural replacements of resources are not outpaced by consumption.
