What is an ecological footprint?
A measure of the impact of a person or community on the environment, expressed as the amount of land required to sustain their use of natural resources.
How is an ecological footprint calculated?
By assessing the land area required for food production, energy consumption, waste absorption, and resources needed to sustain an individual's or population's lifestyle.
What are the main components of an ecological footprint?
carbon footprint, built-up land, forests, cropland, grazing land, and fishing grounds.
What is biocapacity?
The capacity of an area to generate renewable resources and absorb wastes.
What does it mean if a country's ecological footprint exceeds its biocapacity?
The country is in ecological deficit, consuming resources faster than they are regenerated and accumulating waste faster than it can be absorbed.
What is environmental value system (EVS)?
A particular worldview or set of paradigms that shapes the way an individual or group perceives and evaluates environmental issues.
Name three main types of environmental value systems.
Ecocentric, anthropocentric, and technocentric.
Describe the ecocentric value system.
A nature-centered philosophy that prioritizes ecological balance and intrinsic value of all living organisms over human needs and wants.
Describe the anthropocentric value system.
A human-centered philosophy that considers humans as the most important entity and values the environment mainly for its usefulness to humans.
Describe the technocentric value system.
A technology-centered philosophy that believes technological innovation and solutions can resolve environmental problems and provide resources for human needs.
How does the ecological footprint relate to sustainability?
A lower ecological footprint generally indicates a more sustainable lifestyle, as it suggests that fewer natural resources are being consumed and less waste is being produced.
What is the "Earth Overshoot Day"?
The date each year when humanity's demand for ecological resources exceeds what Earth can regenerate in that year.
What role does consumption play in the ecological footprint?
Higher consumption levels lead to a larger ecological footprint due to increased resource use and waste generation.
How can individuals reduce their ecological footprint?
By adopting sustainable practices such as reducing energy consumption, minimizing waste, using public transport, consuming less meat, and supporting sustainable products.
What is the significance of value systems in managing ecological footprints?
Value systems influence behaviors and policies that affect resource use and environmental impact, shaping how societies respond to ecological challenges.
What are some challenges in reducing ecological footprints on a global scale?
Economic inequality, differing national priorities, technological limitations, and varying cultural values and lifestyles.
