Biodiversity, biocapacity and better choices

the EcologicalFootprintThe Ecological Footprint tracks humanity’s demands on thebiosphere by comparing humanity’s consumption againstthe Earth’s regenerative capacity, or biocapacity. It does thisby calculating the area required to produce the resourcespeople consume, the area occupied by infrastructure,and the area of forest required for sequestering CO2 notabsorbed by the ocean (see Galli et al., 2007; Kitzes et al.,2009 and Wackernagel et al., 2002).© National Geographic Stock / Jim Richardson / WWF-CanonLights of Chicago city burn brightly, consuming large amounts ofelectricity, Illinois, United States.
