The environmental impact of irrigation includes the changes in quantity and quality of soil and water as a result of irrigation and the ensuing effects on natural and social conditions at the tail-end and downstream of the irrigation scheme. The impacts stem from the changed hydrological conditions owing to the installation and operation of the ...
Human ecology has a history of focusing attention on humans' impact on the biotic world. [ 1 ] [ 34 ] Paul Sears was an early proponent of applying human ecology, addressing topics aimed at the population explosion of humanity, global resource limits, pollution, and published a comprehensive account on human ecology as a discipline in 1954.
Human impact on the environment (or anthropogenic environmental impact) refers to changes to biophysical environments [14] and to ecosystems, biodiversity, and natural resources [15] caused directly or indirectly by humans.
Ecology is an employed science of restoration, repairing disturbed sites through human intervention, in natural resource management, and in environmental impact assessments. Edward O. Wilson predicted in 1992 that the 21st century "will be the era of restoration in ecology". [ 166 ]
In 1996, Wackernagel and Rees published the book Our Ecological Footprint: Reducing Human Impact on the Earth.

Human activities have a range of impacts on the environment, both positive and negative. Many activities have profound negative impacts on the environment that create direct and indirect stressors on ecosystems. These stressors have an additive, synergistic or antagonistic effect on one another, creating cumulative effects to the environment ...
Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming. These impact marine ecosystems and food webs and may result in consequences as yet unrecognised for the biodiversity and continuation of marine life forms. [3]
Because of the impact of humans on the natural environment in the recent geological period, the term ecological crisis is often applied to environmental issues caused by human civilizations such as: the climate crisis, biodiversity loss and plastic pollution which have emerged as major global challenges during the first few decades of the 21st ...
