Human impact on the natural environment Natural environment is of crucial importance for social and economic life. We use the living world as a resource for food supply an energy source a major source of medicines natural resources for industrial products In this respect the diversity of nature not only offers man a vast power of choice for his current needs and desires.
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 scheme.
An irrigation scheme often draws water from the river and distributes it over the irrigated area. As a hydrological result it is found that: These may be called direct effects.
Effects on soil and water quality are indirect and complex, and subsequent impacts on natural, ecological and socio-economic conditions are intricate.
In some, but not all instances, water logging and soil salinization can result. However, irrigation can also be used, together with soil drainage, to overcome soil salinization by leaching excess salts from the vicinity of the root zone.

According to a article in the journal Science, " soot " found on ceilings of prehistoric caves provides ample evidence of the high levels of pollution that was associated with inadequate ventilation of open fires.|
As a hydrological result it is found that the level of the water descends. Irrigation projects can have large benefits, but the negative side effects are often overlooked. As a result of this massive diversion of freshwater, lakes, rivers, and creeks are running dry, severely altering or stressing surrounding ecosystems, and contributing to the extinction of many aquatic species.
Forannual average soil loss by sheet, rill and wind erosion on non-federal US land was estimated to be On uncultivated cropland, the recent average total soil loss has been 2.
The amount due to meat production is some fraction of that due to livestock. However, many estimates use different sectoral assignment of some emissions. Over the decade throughatmospheric methane content increased by an average of only 6 Tg per year because nearly all natural and anthropogenic methane emission was offset by degradationwhile atmospheric carbon dioxide increased by nearly 15, Tg per year.
Although reduction of methane emissions would have a rapid effect on warming, the expected effect would be small. Management practices that can mitigate GHG emissions from production of livestock and feed have been identified.
Excessive use of vegetation by grazing can be especially conducive to land degradation in dry areas. There are several published estimates of water use associated with livestock and meat production, but the amount of water use assignable to such production is seldom estimated.
However, it would be misleading simply to assign that associated rangeland green water use to beef production, partly because that evapotranspirational use occurs even in the absence of cattle.
Even when cattle are present, most of that associated water use can be considered assignable to production of terrestrial environmental values, because it produces root and residue biomass important for erosion control, stabilization of soil structure, nutrient cycling, carbon sequestration, support of numerous primary consumers, many of which support higher trophic levels, etc.
Withdrawn water from surface and groundwater sources is used for livestock watering, and in some cases is also used for irrigation of forage and feed crops.
Impairment of water quality by manure and other substances in runoff and infiltrating water is a concern, especially where intensive livestock production is carried out.
In the US, in a comparison of 32 industries, the livestock industry was found to have a relatively good record of compliance with environmental regulations pursuant to the Clean Water Act and Clean Air Act,  but pollution issues from large livestock operations can sometimes be serious where violations occur.
Various measures have been suggested by the US Environmental Protection Agency, among others, which can help reduce livestock damage to streamwater quality and riparian environments.This comprehensive overview details the potential environmental impacts of natural gas use and extraction, including its effects on water supplies, global warming emissions, air pollution, and wildlife.
Water, air, and soil are three natural resources that we cannot live without. and mining are also monitored to ensure compliance with air regulations for human health and to monitor possible impacts to natural resources. water, or soil will directly or indirectly affect a natural area, either immediately or in the future.

Particles suspended in air by wind are easily inhaled and accumulate in lung tissues causing major respiratory problems. Journal description.

HUMAN IMPACT. HOW DOES FARMING CHANGE THE LANDSCAPE? Many human activities also produce POLLUTION, which is damaging the Earth’s environment. which creates problems such as air and water pollution, and GLOBAL WARMING.
WHAT CHALLENGES FACE THE HUMAN POPULATION?
Perhaps the most obvious examples of a negative human impact on the environment is water pollution. It's obvious we need water to survive but few people realize how much we need and just how much is available. the degradation of the Earth's surfaces and soil, is caused by human activity and a misuse of natural resources.
Causes of land. Impacts of erosion on air quality: Soil particles blown by the wind into the air have a major impact on human and animal health. Particles suspended in air by wind are easily inhaled and accumulate in lung tissues causing major respiratory problems. makers, scientists, businesses and individual citizens generally accept and understand that air and water pollution can have negative impacts on human health, but the impacts of such soil pollution on our health have had a much lower.
