A major stationary source is a source that emits more than a certain amount of a pollutant as defined by the U. S. Environmental Protection Agency ( EPA ).

Based on a research project by the Environmental and Cultural Conservation in Inner Asia ( ECCIA ) from 1992 to 1995, satellite images were used to compare the amount of land degradation due to livestock grazing in the regions of Mongolia, Russia, and China.

Environmental Impact Assessment ( EIA ) studies need a significant amount of primary and secondary environmental data.

The Environmental Protection Authority, however, raised concerns in November 2005 about the amendment, saying that it " would, in part, be inconsistent with the conservation and protection of significant environmental and geoheritage values in the area ", and recommended that the amount of reserves be greatly increased.

Environmental variables include amount of space available and nature of the territory surrounding the interaction.

A case study conducted by the Department of Civil, Architectural, and Environmental Engineering at the University of Miami that compared three green products and their non-green counterparts found that even though both the green products and the non-green counterparts both emitted levels of VOCs, the amount and intensity of the VOCs emitted from the green products were much safer and comfortable for human exposure.

* The modern Environmental movement, which began in the 1960s with concern about air and water pollution, became broader in scope to including all landscapes and human activities.

* Environmental health movement dating at least to Progressive Era ( 1890s-1920s ) urban reforms including clean water supply, more efficient removal of raw sewage and reduction in crowded and unsanitary living conditions.

Environmental issues can include erosion, formation of sinkholes, loss of biodiversity, and contamination of soil, groundwater and surface water by chemicals from mining processes.

Environmental issues include the high level of air pollution from vehicle emissions, water pollution from the dumping of raw sewage, tap water not being potable, and deforestation.
