What is an ecological footprint

  • Definition: The ecological footprint represents how much land is needed to supply all resources and absorb all wastes of a particular population.
  • Think of it as an environmental credit card statement, showing how much we "charge" the Earth.

Real-world Example: Imagine if every time you bought food, clothes, or used electricity, you took up a tiny piece of land. By the end of the month, you could see just how much land you "used" based on your choices!

Connection to carrying capacity

  • It's the inverse of carrying capacity.
  • While carrying capacity looks at how many people an area can support, ecological footprint looks at how much land is needed to support those people.

Fun Fact: If everyone lived like an average American, we'd need 5 Earths to sustain us!

Measuring units

  • Measured in global hectares (gha).
  • You might see the total footprint for an area or a per-person footprint.

Example: Country A might have a footprint of 1 million gha, but each citizen only uses 2 gha.
