Ecological effect or degradation is created by the consolidation of an effectively substantial and expanding human populace, constantly expanding monetary development or per capita fortune and the application of asset exhausting and polluting technology. Environmental degradation is one of the largest threats that are being looked at in the world today. The United Nations International Strategy for Disaster Reduction characterizes environmental degradation as the lessening of the limit of the earth to meet social and environmental destinations, and needs. Environmental degradation can happen in a number of ways.
Human overpopulation The human population on Earth is expanding rapidly which goes hand in hand with the degradation of the environment at large measures. Production industries are venting smoke and discharging chemicals that are polluting water resources.
The smoke that is emitted into the atmosphere holds detrimental gases such as carbon monoxide and sulfur dioxide. The high levels of pollution in the atmosphere form layers that are eventually absorbed into the atmosphere.
The available fresh water being affected by the climate is also being stretched across an ever-increasing global population. Even though some areas may see an increase in freshwater supply from an uneven distribution of precipitation increase, an increased use of water supply is expected.
The next 50 years will likely be the last period of rapid agricultural expansionbut the larger and wealthier population over this time will demand more agriculture.
Changes in climate, especially the changes in precipitation and evapotranspiration predicted by climate models, will directly affect soil moisture, surface runoff, and groundwater recharge.
In areas with decreasing precipitation as predicted by the climate models, soil moisture may be substantially reduced. Irrigation increases salt and nutrient content in areas that would not normally be affected, and damages streams and rivers from damming and removal of water.
Fertilizer enters both human and livestock waste streams that eventually enter groundwater, while nitrogen, phosphorus, and other chemicals from fertilizer can acidify both soils and water.
Certain agricultural demands may increase more than others with an increasingly wealthier global population, and meat is one commodity expected to double global food demand by which directly affects the global supply of fresh water. Cows need water to drink, more if the temperature is high and humidity is low, and more if the production system the cow is in is extensive, since finding food takes more effort.
Water is needed in processing of the meat, and also in the production of feed for the livestock.
Manure can contaminate bodies of freshwater, and slaughterhouses, depending on how well they are managed, contribute waste such as blood, fat, hair, and other bodily contents to supplies of fresh water.
Reservoirs are operated based on past hydrologic records, and irrigation systems on historical temperature, water availability, and crop water requirements; these may not be a reliable guide to the future.
Re-examining engineering designs, operations, optimizations, and planning, as well as re-evaluating legal, technical, and economic approaches to manage water resources are very important for the future of water management in response to water degradation. Another approach is water privatization; despite its economic and cultural effects, service quality and overall quality of the water can be more easily controlled and distributed.
Rationality and sustainability is appropriate, and requires limits to overexploitation and pollution, and efforts in conservation.The Millennium Ecosystem Assessment, a UN-commissioned initiative to study ways to prevent environmental degradation, warns that the loss of just a few species may "result in a collapse" of the Earth's ecosystem, which could worsen the effects of climate change and diminish the global food supply.
Dec 03, · Pope Francis’ decisive statement on climate change shifts the focus from a question of science to a question of values. He argues that climate change is a global problem with far reaching environmental and social consequences, with the m ost dire predictions for the poorest of the world.
