How the Environment Effects Food and Supply

How the Environment Effects Food and Supply admittanceThe purpose of this report is to discuss the current state of nutrition and purlieu in the field of natural re springs like s oil color, naval, climate and thawing glaciers and their sees.By examining a range of academic articles in summary books, newspaper articles and meshwork sites on the topic of pabulum and milieu, this report states the situation of natural resources, environs contamination, over development and some orbiculate phenomenon fixd by international worming and function glaciers. The report indeed considers the further development and world(prenominal) worming, melt glaciers make on sustenance and environment.Floods and droughtsIn the beginning of this essay, the issue of how environmental disasters opposition intellectual nourishment leave behind be discussed. It is clear that our Mother Earth is getting hotter, with the effect of global pepperinessing plant. It is because of Greenhou se effect which is imputable to the massive and rapid development of several industries from developing countries. It was proved that the cadence of CO2 in the atmosphere has maturationd from 316 ppm in 1958 to 385 ppm in 2008 (Kirkham 2011, p.370). It has worsened the issue of melting glaciers which, in turn, causes flooding and droughts over many a(prenominal) areas in the world.The high fate of glacier melting is the main reason of the rise of sea level which causes floods in over the world. Unexpected floods could impact seriously on trim backs growth, it grass admit a negative effect on the financial performance of tillage as a upshot of crop damage trim crop and livestock yield and quality/condition (Thorne, Evans and Rowsell 2007, p.130). It means that flooding does non altogether adjoin the quantity provided the quality of forage source as well. For instance, a recent flooding that happened in 25th of horrible in 2012 in Burma after several weeks of contin uously raining has control eighty-five thousands of spate homeless as well as more than two hundred thousand hectares of sift field have been swamped (The protector 2012). It was too expected to require a long while for the people and fields to recover.While there are countries that are struggling with floods, drought is also a problem in others because the weather changes wind patterns that moves besmirch and humidity through the post that causes the imbalance in body of water distribution. Since whitethorn this year, North Korea has been suffering the close to severe drought in cv years which threatened to damage this countrys breadbasket, especially when this country has already experient a critical lack of food for thought. North Korean was also notified an prefigure amount of 3.5 mil king of beasts people are with the risk of malnutrition and famine (The telecommunicate 2012).Because of these destructions, it is possible that in the near future, countries using r ice as a main food go out have to face with a massive shortage of food, while Burma and North Korea are considered sources for rice suppliers. Furthermore, even if the amount of food could be sustained, its quality is unsure due to the pollution issues. marine pollutionMarine pollution so-and-so be traced back as early to the Roman times. Industrial waste, farm runoff and trash cast a route into the oceans have caused much imbalance to the ecosystem in which many organisms thrive in. condescension many efforts made by eco-friendly organizations and campaigns to reduce pollution, it is still happening at a large scale.Pollution is essentially the introduction of pernicious contaminants not collapse of a natural ecosystem. They whitethorn range from the man-made pollutants like chemicals, pesticide, industrial residue, oil, sewage, plastics and other solids. These contaminants end up contaminating not and the water in which much of the marine spirit live in but they also cau se a disruption in the global food chain. When fish consume these contaminants, domain are simultaneously alter as they catch and eat the fish. Therefore, radioactive or poisonous contaminants may drastically harm us and as much(prenominal) pollution does propel us as much as it does the marine ecosystem.Excessive pollution may even cause any entire ecosystem to collapse and then fishing may be near impossible once this happens. seek will become scarce as an entire food chain will be broken beginning with water in the ocean creation unsuitable for inhabiting.Oil spillsOil spills are usually the most common of all marine pollution. ofttimes of it comes from spillage from large ships and vessels as well as oil rigs. In addition, drainages and rivers also transport oil into the oceans from cities and industry. As oils density is lesser than water, it usually stays at the pop out which causes sea mammals and birds to be affected much more than fishes as it causes these anima ls to foul when they drink the water or come out to the surface to faint due to the toxins of the oil.Sewage disposalAnother cause of pollution if sewage disposal. Much urban sewage that is dumped into the ocean is untreated or under treated. Sewage unaccompanied contains much bacteria and even diseases. Fishes may sometimes eat these sewage and the bacteria may then thrive in them. This affects us when we catch and later consume the fishes, causing the bacteria to then be transferred into our bodies. Aside from affecting us in that manner, humans may also be affected by the diseases in the water and beaches closures may occur.Toxic chemicalsToxic chemicals make up the bulk of marine pollution. Much of these toxic chemicals are dumped into the oceans deliberately despite much international laws ban such dumping. Accidental leakages from industries also cause these chemicals to disseminate through soil, water and through water vapour in the air. From the tiniest organisms in th e ocean such as plankton to larger animals up the food chain like charged bears. They become affected by these chemicals as they are able to locomote long distances through currents in the ocean. People, who are at the highest end of the food chain, end up consuming the highest chemical load as it is compute up the food chain.To conclude, our food is largely hooklike on the physical environment that it comes from. Pollution causes much disarray to the purity and freshness of our food as it affects us directly once we eat them. Fish that has been sully by toxins from chemicals may cause bearcer, damage to immune systems, behavioral problems, reduced fertility and even death in extreme cases.Global warming and its effects on sea levelsGlobal warming is causing a drastic problem to humans and their food source alike, namely fish, by causing alarming increases in sea levels. The cause of global warming is initiated by the babys room effect. The greenhouse effect is when the sun s heat is pin down in the earths atmosphere when greenhouse gases cause it to be radiated back to earth. Normally, some heat from the sun is absorbed into the earths surface while the rest is radiated back to space. When humans burn fossil fuels like petroleum, natural gas and coal, they create inordinate amounts of speed of light dioxide which are the major components of greenhouse gases.When excessive heat is pinped in the earths atmosphere, this causes our earth to heat up beyond normal temperatures. This increase in temperature is causing ice caps on Mount Kilimanjaro and ice sheets in Antarctica and Greenland to melt. When this happens, water levels will rise which will cause many problems which will upset the balance in nature. Cold water fish will not be able to survive as the water would be too warm. This would cause problems for people fishing them as a food source. Even coral reefs are dying as a result of the increase in water temperatures. This in turn could cause ma ny species of fish who call it home to die which could in turn affect humans fishing for them. Another great drastic issue is elevation water levels. Research has shown that low lying nations like the Maldives could be on the whole submerged should this occur. Such a rise would have a annihilative impact on low-lying island countries, such as the Indian Oceans Maldives, which would be entirely submerged. (Stefan Lovgren, 2004). Densely populated areas like Nile Delta and Bangladesh would become uninhabitable as well. Not sole(prenominal) will fishing be difficult but people will have a greater problem at finding higher ground suitable for living.An imbalance in natures food chain would be caused by global warming that could drastically affect fishes as food source. As ice sheets melt in the Antarctic, the charged bears living would be adversely affected as the temperature would be increasingly too warm for them to live in. Polar bears are entirely dependent on sea ice, you lose sea ice, you lose polar bears. (Jay Malcolm, 2004). Hence, they may not be able to survive and the seal and sea lion population that would otherwise be controlled by the polar bears as take apart of their diet would multiply and overpopulation may occur resulting in many fishes being eaten and depleted. This depletion would be a negative factor for fisheries and human civilizations living in the northern hemisphere would have to then look for an utility(a) food source which would be difficult as their main source of protein and food are fish.Intrusion of sea waterThe rise in sea level also leads to the intrusion of sea water. As the development environment for rice crops is the fresh water, the increased salinity in soil can hinder rice growth and affect rice production. A study carried out by World Bank (2000) indicates that increased salinity alone from a 0.3 meter sea level rise will cause a net decrease of 0.5 million metric tons of rice production. Some low-lying deltas (whi ch are the major rice crops in the world) of such river systems as the Ganges, the Mekong, the Nile, the Yellow, and so forth, have been affected by tidal wave. For example, as reported by FAO (1998), there were estimated amounts of 650,000 ha of saline soils along the coastal belt in the Mekong River Delta and 350,000 ha in the Red River Delta of Vietnam.The release of pesticides water in lakes or rivers where the melting glacier flows through can be pollute with pesticides. Some types of pesticides which contained harmful elements used to be used in awkward production but they then were banned worldwide years ago. well-nigh of the pesticides evaporated into the air and were finally trapped in layers of glaciers. Now, the rapid glacial melting is causing these hazardous chemicals to be released back into the environment, lakes, and rivers. For example, organochlorine is a type of pesticide having harmful contents. It was banned in entire USA due to its bad effects on humans heal th like leading to headache, dizziness, muscle weakness, or even cancer (Delaware Health and Social Services, 2010). This chemical, according to Blais (2001), shows an increase in one of the sub-alpine lakes in Canada. Such type of contamination can add up about negative impacts on the underwater ecology and creatures, while at the same time affects the source of water used for humans life as well as farming.Global SolutionThe only way to slow down glaciers melting is to slow global warming.The global greenhouse effects requires a global solution, which requires the participation of the entire global community. (Rogers, 2012) We only have one earth, the protection for it need all citizen take part in.Humankind has become dependent on burning fossil fuels to underpin our way of life, but it increases global warming at an unnatural rate. To reclaim the glaciers we need to utilize alternative energy sources, increase our energy strength and decrease our individual carbon output. (R ae, 2012)There are many alternative energy available. Solar panels are made up of solar cells that trap the heat from the sun and convert it into energy. Wind turbines are towers that use the energizing energy from the wind to generate authority. Biofuels such as ethanol can be produced in your back yard by fermenting and meld vegetable, fruit and grain waste ethanol is used to make biodiesel fuel, a clean burning fuel for diesel engines. Electric cars are powered or else of relying of the highly polluting internal combustion engine. Tidal and wave power utilize the massive power of the ocean by harnessing the energy with generators primed(p) on the ocean floor. (Rae, 2012)For individuals, try to take public transportation instead drive ourself ride a bicycle if it helps walk or swan to destination is also a good way to save time and strengthen body. Save power at home by victorious shorter showers, recycling used water, turning off power for resting television, computers. Li ttle things can make a cock-a-hoop difference if done in a large scale, and theyll go a long way toward reducing carbon footprint and saving the glaciers, slow down other effects of global warming.ConclusionThis report has stated the currently major effects that environment made to the food growth and supply.They are the field pollution due to over fertilization, unbalance of marine organism caused by over fishing, air pollution because of industrialization and urbanization. And even the melting glaciers which is a result of global warming has being a big concern When we see melt in places that we havent seen before, at least in a long spot of time, it makes you sit up and ask whats happening. said NASA chief scientist Waleed Abdalati. Its a big signal, the meaning of which were going to sort out for years to come.It is not only simply the food or the environment that we should think about, but also the connection between. More systematic development need to be considered by gover nment, organizations and companies.
