For example, "green water" use is evapotranspirational use of soil water that has been provided directly by precipitation; and "green water" has been estimated to account for 94% of global beef cattle production's "water footprint", [90] and on rangeland, as much as 99.5% of the water use associated with beef production is "green water".
In 1967, Roderick Nash published Wilderness and the American Mind, a work that has become a classic text of early environmental history.In an address to the Organization of American Historians in 1969 (published in 1970) Nash used the expression "environmental history", [4] although 1972 is generally taken as the date when the term was first coined.

This has also shown that the technology has been used to minimize energy use, society always wants new technology no matter if it affects the environment good or not, but ICT has been cutting back and putting out better technology for our environment while still being able to communicate through society.

Since the start of science-based environmental monitoring, a number of quality indices have been devised to help classify and clarify the meaning of the considerable volumes of data involved. Stating that a river stretch is in "Class B" is likely to be much more informative than stating that this river stretch has a mean BOD of 4.2, a mean ...
A modified ecological footprint that takes biodiversity into account has been created for use in Australia. [98] Ecological footprint for many years has been used by environmentalists as a way to quantify ecological degradation as it relates to an individual. Recently, there has been debate about the reliability of this method. [99]
The schematic with the nested ellipses emphasizes a hierarchy of the dimensions, putting environment as the foundation for the other two. Sustainability is a social goal for people to co-exist on Earth over a long period of time. Definitions of this term are disputed and have varied with literature, context, and time.
Ongoing changes in climate have had no precedent for several thousand years. [54] Multiple independent datasets all show worldwide increases in surface temperature, [55] at a rate of around 0.2 °C per decade. [56] The 2014–2023 decade warmed to an average 1.19 °C [1.06–1.30 °C] compared to the pre-industrial baseline (1850–1900). [57]
A particular case of environmental conflicts are forestry conflicts, or forest conflicts which "are broadly viewed as struggles of varying intensity between interest groups, over values and issues related to forest policy and the use of forest resources". [49] In the last decades, a growing number of these have been identified globally. [50]
