Measuring Our Impact The Essentials of Ecological Footprints

The video explains the concept of an ecological footprint, which measures the land and water area required to sustain a population's resource consumption. It details the components of an ecological footprint, including cropland, forest land, built-up land, carbon sequestration, grazing land, and fishing grounds. The video discusses variations in ecological footprints by country and individual, influenced by factors like diet and energy use. It highlights the sustainability challenge, noting that current footprints exceed Earth's biocapacity. The video also explores technocentric views on improving sustainability through technology. Finally, it provides exam tips for understanding and assessing ecological footprint concepts.

What is an ecological footprint?

• The number of people living in a specific area

• The total energy consumption of a population

• The area of land and water needed to support a population sustainably

Why is carbon sequestration important in calculating an ecological footprint?

• It determines the amount of land needed for housing

• It calculates the number of trees in a forest

• It helps in measuring water usage

• It accounts for the carbon dioxide absorbed by plants
