<speciesfyi-glossary slug="ecological-footprint"></speciesfyi-glossary>Definition
A measure of human demand on Earth's ecosystems expressed as the area of biologically productive land and water required.
Detailed Explanation
Currently humanity uses the equivalent of 1.75 Earths annually, meaning we consume renewable resources faster than ecosystems regenerate them. High-income nations have footprints 5-10 times larger than low-income ones, highlighting equity issues in sustainability. Shrinking the footprint requires shifting diets toward plants, reducing energy use, and improving resource efficiency across supply chains.
