Food waste has its own disadvantages especially to the environment

Food waste has its own disadvantages especially to the environment.Almost more than 50 percent of the waste take place along the process of production, yield and storage stage and the remaining waste occurs during processing, dealing out and utilization stages or the “downstream”. We can say that the higher income regions has been showing greater food loss regions during the consumption phase. Developing countries were more often to waste food at the production phase as they are lacking of proper harvest methods and infrastructure. The environmental effects increases rapidly when greater amount of food was wasted. This is due to we have to take into account the energy and the natural raw materials disburse in processing, shifting, storing and cooking it.
On the other hand, when food waste is thrown at landfills, large amount of methane produced . Methane is well known as a most strong greenhouse gas than carbon dioxide. In term of scientific theory, the greenhouse gases like carbon dioxide, methane, carbon monoxide and chlorofluorocarbon enclosed the infrared radiation and heat up the earth’s atmosphere, which end up causing global warming and climate change. Food waste is highly to the great waste of fresh water and underground water resources. For instance, nearly 1000 litres which is 1 millilitres of water are wasted you pour one glass of milk down the drain because at the end somehow the river water will mix with the drain water which is already contaminated with the milk.

There are few sectors which affect the environment in many type of ways as agriculture is one of the major sector which influence the environment through its effects on ecosystems, land cover and on regional and global cycles of water, nutrients and carbon. The climate in our world has been changed by the emission of greenhouse gases in atmosphere and reduction of carbon storage in vegetation and soil by the agriculture . The global food system is catogerized as the largest emitter of greenhouse gases to the atmosphere as it contributes nearly one-third of the total to the atmosphere. Due to the increasing food manufacturing ,more than one environmental effects happens including the carbon sequestration and greenhouse gases emissions.

Nitrogen gas causes several effects to the environment when it was emitted to the surrounding. Nitrogen gas is a particularly restriction to plant productivity, a crucial vitality and economic input in agroecosystems and a major resource of environmental contamination through gaseous and leaching losses. We can use the nitrogen to make fertilizer like fertilizer-N.There are several steps taken to lower the consumption and environmental imprints of the fertilizer-N, while retaining or even increasing productivity of the plant including the advancement of synthetic nitrogen-fixing system for key crop species.That is the reason why nitrogen have harmful consequences when used in large quantities or imperfectly managed.As Africa drasticly wider the use of nitrogen to reach food security and it is crucial to study from past experiences.
