The Human Footprint increased by 9% from 1993 to 2009, at least partly attributable to a human population increase of 23% and a global economy increase of 153% during the same period. [3] Though population and economic growth far exceed the growth of the Human Footprint, the areas that saw increased human influence were those with the highest ...
This is a list of countries by planetary pressures–adjusted human development index (PHDI), as published by the UNDP in its 2020 Human Development Report. [1] The index captures the HDI of a country adjusted for ecological and environmental factors like carbon dioxide emissions per person and material footprint.
The ground pressure of motorized vehicles is often compared with the ground pressure of a human foot, which can be 60 – 80 kPa while walking or as much as 13 MPa for a person in spike heels. [ 3 ] Increasing the size of the contact area on the ground (the footprint ) in relation to the weight decreases the unit ground pressure.
The ecological footprint measures human demand on natural capital, i.e. the quantity of nature it takes to support people and their economies. [ 1 ] [ 2 ] [ 3 ] It tracks human demand on nature through an ecological accounting system.

Reduction of one's carbon footprint for various actions. Human civilization has caused the loss of 83% of all wild mammals and half of plants. [29] The world's chickens are triple the weight of all the wild birds, while domesticated cattle and pigs outweigh all wild mammals by 14 to 1.
This is a list of countries by ecological footprint. The table is based on data spanning from 1961 to 2013 from the Global Footprint Network's National Footprint Accounts published in 2016. Numbers are given in global hectares per capita. The world-average ecological footprint in 2016 was 2.75 global hectares per person
Based on the relationship between human footprint length and body size, twelve Happisburgh prints that are preserved well enough to measure are consistent with individuals ranging from 93 to 173 cm (3 ft 1 in to 5 ft 8 in) in stature, which may mean some of the trackmakers were children. By this logic, the three biggest footprints—equating to ...
