The effects of human activity on the environment

Asian Development Bank We as humans have become dependent on luxuries such as cars, houses, and even our cell phones. But what does our love for manufactured metallic and plastic goods do to the environment? Human activity can be directly attributed to the cause of hundreds of extinctions in the last two centuries, versus the millions of years that extinctions naturally occur.

The effects of human activity on the environment

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.

Human activities in respect of disposal of sewage wastes, solid wastes, municipal wastes, agricultural and industrial wastes cause the environment unfit for day to day use. Besides, polluted water spreads or leads to different diseases. Human activity is causing environmental degradation, which is the deterioration of the environment through depletion of resources such as air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution. Humanity's effects on the global environment have grown more and more significant since becoming the dominant species on Earth. According to Smithsonian Magazine, many scientists refer to the current geological time period as "The Anthropocene Era," meaning "the new period of man.".

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.

Air Pollution

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. 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.

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.Effects of Mining Activities on Environment Mining is the extraction (removal) of minerals and metals from earth.

Manganese, tantalum, cassiterite, copper, tin, nickel, bauxite (aluminium ore), iron ore, gold, silver, and diamonds are just some examples of what is mined.

Humanity's effects on the global environment have grown more and more significant since becoming the dominant species on Earth.

According to Smithsonian Magazine, many scientists refer to the current geological time period as "The Anthropocene Era," meaning "the new period of man.".

Human activities in respect of disposal of sewage wastes, solid wastes, municipal wastes, agricultural and industrial wastes cause the environment unfit for day to day use.

Land Pollution

Besides, polluted water spreads or leads to different diseases. Human activities contribute to climate change by causing changes in Earth’s atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness. The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas to the atmosphere.

Humans impact the environment in several ways. Common effects include decreased water quality, increased pollution and greenhouse gas emissions, depletion of natural resources and contribution to global climate change.

Some of these are the direct result of human activities, whereas others are.
