Human impact: the percentage of human influence relative to the maximum influence recorded for each biome.
Data include:
human population density
land transformation (including global landcover, roads, and cities)
electrical power infrastructure (NOAA night-lights data)
access (via roads, avigable rivers, and coastline) to the land
Humans have been successful in their efforts to av
