# Empirical View
# Land Use of the World Today
The graphic below details the breakdown of global land allocation and use based on areal extent. Only 71 percent of Earth’s land surface is defined as habitable. Humans use half of global habitable area for agricultural production (of the remainder, 37 percent is forested; 11 percent as shrubbery; and only one-percent is utilised as urban infrastructure).
More than three-quarters of our agricultural land is used for the rearing of livestock through a combination of grazing land and land used for animal feed production. Despite being dominant in land allocation for agriculture, meat and dairy products supply only 17, and 33 percent of global caloric and protein supply.
