Recreational vessels Overflying aircraft Commercial vessel engine noise, usually a low frequency sound, may contribute to masking and habitat displacement. Intense low or mid-range sonar, used by the military and in seismic surveys for oil and gas exploration, as well as ocean floor mapping, can result in any or all of the effects listed below, as can pile driving and any type of explosion. Dredging, drilling and bottom-towed fishing gear all have impacts. As can be seen from the list, it is not just industry and the military contributing to this problem.
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.
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.
Non-solar energy is specified, because solar energy is used in such processes as photosynthesis and hay-drying. Changes in livestock production practices influence the environmental impact of meat production, as illustrated by some beef data.
In the US beef production system, practices prevailing in are estimated to have involved 8. These include waste reduction by conversion of human-inedible crop residues to food, use of livestock as an alternative to herbicides for control of invasive and noxious weeds and other vegetation management,  use of animal manure as fertilizer as a substitute for those synthetic fertilizers that require considerable fossil fuel use for manufacture, grazing use for wildlife habitat enhancement,  and carbon sequestration in response to grazing practices,   among others.
Conversely, according to some studies appearing in peer-reviewed journals, the growing demand for meat is contributing to significant biodiversity loss as it is a significant driver of deforestation and habitat destruction.The impact of anthropogenic activities on marine environment in Jiaozhou Bay, Qingdao, China: A review and a case study.

Anthropogenic impact in the sea and marine pollution. by Stanislav Patin, translation by Elena Cascio based on "Environmental Impact of the Offshore Oil and Gas Industry". Below you will find a brief introduction to the problem of anthropogenic impact in the sea and marine pollution.
Marine renewable energy devices may produce lower noise levels than many other anthropogenic sources, but have the potential to cause long-term exposure to sessile marine organisms.
Regarding manmade ocean noise as a pollutant is a relatively recent development. 'Our marine environment ' is a joint report by the Ministry for the Environment and Statistics New Zealand. 'Our marine environment ' provides an overview of the pressures New Zealand's marine environment faces, how it is changing, and the impacts on our biodiversity, economy, and way of life.
Antarctica is the most isolated continent on Earth, but it has not escaped the negative impacts of human activity. The unique marine ecosystems of Antarctica and their endemic faunas are affected. Human impact on the environment or anthropogenic impact on the environment includes changes to biophysical environments and ecosystems, biodiversity, and natural resources caused directly or indirectly by humans, including global warming, environmental degradation (such as ocean acidification), mass extinction and biodiversity loss, ecological crisis, and ecological collapse.
