Wetland vary widely in their salinity levels, climate zones, and surrounding geography and play a crucial role in maintaining biodiversity, ecosystem services, and support human communities. [1] Wetlands cover at least six percent of the Earth and have become a focal issue for conservation due to the ecosystem services they provide.

However, in both cases outcomes are decided by human responses to the ...
In 1996, Wackernagel and Rees published the book Our Ecological Footprint: Reducing Human Impact on the Earth. [ 15 ] The simplest way to define an ecological footprint is the amount of environmental resources necessary to produce the goods and services that support an individual's lifestyle, a nation's prosperity, or the economic activity of ...
Environmental studies (EVS or EVST) is a multidisciplinary academic field which systematically studies human interaction with the environment.Environmental studies connects principles from the physical sciences, commerce/economics, the humanities, [1] and social sciences [2] to address complex contemporary environmental issues.
Wetlands exist on every continent, except Antarctica. [19] The water in wetlands is either freshwater, brackish or saltwater. [18] The main types of wetland are defined based on the dominant plants and the source of the water. For example, marshes are wetlands dominated by emergent herbaceous vegetation such as reeds, cattails and sedges.
