The consequences of human activities contributing to the destruction of our planet

The Aral Sealocated on the Uzbekistan-Kazakhstan border, was once the fourth largest lake, but has now shrunk by 75 percent see image above.

An irrigation scheme often draws water from the river and distributes it over the irrigated area. By contrast, financial markets adjust in minutes, administered-market prices in weeks, labor markets in years, and the economic long run is usually reckoned at no more than two decades.

About 18 million acres of trees are clear-cut every year for wood. It is wasteful for society to expend resources to prevent changes that will not occur anyway.

As a hydrological result it is found that the level of the water descends. I hope scientists will find an effective method to eliminate the green house effect soon. Although European countries were slower to adopt these technologies, they too eventually followed suit.

It assumes that expenditures made now could otherwise be invested at compound interest in improvements in human well-being. The long term effect on marine life can include cancer, failure in the reproductive system, behavioral changes, and even death.

Furthermore, because the rain forest is shrinking, its carbon-dioxide absorbing capacities are being diminished, which in turn means more of the heat-trapping gas is reaching the upper atmosphere, causing global temperatures to rise. 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.

In some countries, the smog caused by air pollution is deadly and can block out the sun in a dense haze. The quickest solution to deforestation would be to simply stop cutting down trees. Some scientists predict that some cities nearby the sea will be submerged under the sea in a few next decades.

It involves permanent end of forest cover to make that land available for residential, commercial or industrial purpose. Tropical and mature forests are being damaged by the lumber and paper trade.

Previously, consumers had bought their refrigerated food at the store just before eating it, since efficient and reliable household refrigeration was not generally available.

These factories have released many toxic effluents materials into the river, the soil and the sea. Action now is more feasible and effective than action later.

Management practices that can mitigate GHG emissions from production of livestock and feed have been identified. Humans are now conducting large-scale uncontrolled experiments on the global environment by changing the face of the earth and the flows of critical materials at unprecedented rates.

According to the Union of Concerned Scientiststhree billion tons of CO2 enters the atmosphere every year from deforestation. Runoff from farmland often carries large amounts of fertilizer into rivers and streams that eventually drain into the sea.

Nitrogen-rich fertilizers applied by farmers inland, for example, end up in local streams, rivers, and groundwater and are eventually deposited in estuaries, bays, and deltas. 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.

Social scientists specializing in conflict have developed generalizations that might be more thoroughly applied to environmental conflict.

More research seems warranted to use existing knowledge about conflict to illuminate the ways social conflict may result from global environmental change.

How Much Does Human Activity Affect Climate Change?

Environmental degradation is the disintegration of the earth or deterioration of the environment through consumption of assets, for example, air, water and soil; the destruction of environments and the eradication of wildlife.

It is characterized as any change or aggravation to nature’s turf seen. Do something for our planet, print this page only if needed. Even a small action can make an enormous difference when millions of people do it! How do human activities contribute to climate change and how do they compare with natural influences?

The European Environment Agency (EEA) is an agency of the European Union. Legal. Scientists have high confidence that global temperatures will continue to rise for decades to come, largely due to greenhouse gases produced by human activities.

How Much Does Human Activity Affect Climate Change?

The Intergovernmental Panel on Climate Change (IPCC), which includes more than 1, scientists from the United States and other countries, forecasts a temperature rise of. Some human activities that cause damage (either directly or indirectly) to the environment on a global scale include human reproduction, overconsumption, overexploitation, pollution, and deforestation, to.


Current Environmental Issues

Posted by: thanhnguyen on: May 15, In: Uncategorized; Obviously, human activities have made many negative effects to the environment and our planet. phê bình đoạn trên: human activities have made many negative effects to the environment and our. However, the trees on our planet are being depleted at a very fast rate.

According to some estimates, more than 50 percent of the tree cover has disappeared due to human activity. Although humans have been practicing deforestation since ages, it was in the mids that forests began to be destroyed at an unprecedented rate.
