Ecological Footprint Flashcards

Questions and Answers

Define ecological footprint and discuss why we calculate it.

The ecological footprint is the amount of productive land needed to support each person's lifestyle. We calculate ecological footprint to show individuals how they affect the environment personally.

How does meat consumption affect your ecological footprint? Describe why.

Meat consumption affects your ecological footprint because it takes a lot of energy to feed and prepare a cow for market. This involves multiple steps, such as farming corn for feed, which has a larger footprint compared to eating vegetables.

What are the 4 lifestyle categories that an ecological footprint is broken down into? Give one example of each that would cause a larger ecological footprint.

Mobility, shelter, food, and goods and services. For example, driving a car for mobility, living in a large house for shelter, consuming high amounts of meat for food, and buying many products and services contribute to a larger footprint.

What are the 5 different land uses an ecological footprint is broken down into?

Developed, farmland, pasture, water, and forest. Signup and view all the answers

Describe why the country you reside in is necessary information for calculating your ecological footprint.

The country is needed in calculating your ecological footprint because it influences where you source products, such as from local markets or large retailers like Wal-Mart. Signup and view all the answers

In regards to how the amount of land you require to support your lifestyle is calculated in your ecological footprint, what is the difference between sources and sinks? Provide 2 examples of each.

A source is something that creates pollution, such as cars and factories. A sink is something that absorbs pollution, like oceans and forests. Signup and view all the answers

Study Notes

Ecological Footprint Overview

Ecological footprint measures the productive land required to sustain an individual's lifestyle.
Calculation helps people understand their personal environmental impact.

Meat Consumption and Ecological Footprint

Meat consumption significantly increases ecological footprint due to high energy costs in raising livestock.
Producing beef involves multiple steps, such as farming corn to feed cattle.

Lifestyle Categories of Ecological Footprint

Ecological footprint is categorized into four main areas:
- Mobility: Use of personal vehicles contributes to footprint.
- Shelter: Size and energy consumption of homes affect footprint.
- Food: Meat-heavy diets increase land use.
- Goods and Services: Consumer choices impact ecological sustainability.

Land Use Breakdown

Five types of land use influencing ecological footprint include:
- Developed land
- Farmland
- Pasture
- Water bodies
- Forested areas

Importance of Country in Calculating Footprint

The country of residence influences ecological footprint calculations based on local consumption patterns and resource sourcing.

Sources and Sinks in Ecosystem

Sources: Entities that generate pollution, primarily contributing to CO2 emissions (e.g., cars, factories).
Sinks: Natural systems that absorb pollution, helping mitigate environmental impact (e.g., forests, oceans).

American Ecological Footprint

Americans tend to have one of the largest ecological footprints globally mainly due to widespread vehicle ownership and reliance on non-local products.

Affluence and Ecological Footprint

High affluence can correlate with a low ecological footprint if individuals invest in efficient technologies and sustainable practices.

Human Development Index (HDI)

HDI measures a country's development based on three indices:
- Education level
- Income
- Life expectancy

Largest Component of American Ecological Footprint

Developed land constitutes the majority of the average American's ecological footprint due to its extensive spread across the country.

Earth's Biocapacity

Earth's biocapacity represents the total biological capacity to regenerate resources.
Current usage exceeds this by about 1.5 times, indicating sustainability challenges.
