How the surroundings Results Food and Supply

Keywords: environmental changes food, environmental impact food, environmental impact pollution


The purpose of this statement is to discuss the current state of food and environment in the field of natural resources like earth, ocean, weather and melting glaciers and their affects.

By examining a range of academic articles in summary books, newspapers articles and internet sites on this issue of food and environment, this report states the problem of natural resources, environment pollution, over development plus some global phenomenon triggered by global worming and melting glaciers. The report then considers the further development and global worming, melting glaciers influence on food and environment.

Floods and droughts

In the start of this essay, the issue of how environmental disasters impact food will be discussed. It is clear that our "Mother Earth" is getting hotter, with the effect of global warming. For the reason that of "Greenhouse impact" which is because of the massive and swift development of several establishments from developing countries. It had been proved that the quantity of CO2 in the atmosphere has increased "from 316 ppm in 1958 to 385 ppm in 2008" (Kirkham 2011, p. 370). It offers worsened the issue of melting glaciers; which, in turn, causes flooding and droughts over many areas in the world.

The raised percentage of glacier melting is the primary reason of the surge of sea level which in turn causes floods in around the world. Unpredicted floods could impact critically on crops expansion, it "can have a poor influence on the financial performance of farming as a result of crop damage reduced crop and livestock yield and quality/condition" (Thorne, Evans and Rowsell 2007, p. 130). It means that flooding does not only affect the number but the quality of food source as well. For instance, a recent flooding that took place in 25th of August in 2012 in Burma after weeks of consistently raining has influenced eighty-five thousands of people homeless as well as more than 2 hundred thousand hectares of rice field "have been swamped" (The Guardian 2012). It was also expected to require a long time for the people and fields to recuperate.

While there are countries that are fighting floods, drought is also a problem in others because the weather changes wind patterns that goes cloud and humidity through mid-air that triggers the imbalance in normal water circulation. Since May this year, North Korea has been battling the most severe drought in 105 years which threatened to damage this country's "breadbasket", in particular when this country has recently experienced a crucial lack of food. North Korean was also notified an estimate amount of 3. 5 million people are with the chance of malnutrition and famine (The Telegraph 2012).

Because of these destructions, it is possible that in the near future, countries using rice as a main food will have to face with a huge scarcity of food, while Burma and North Korea are believed resources for rice suppliers. Furthermore, even if the quantity of food could be sustained, its quality is doubtful due to the pollution issues.

Marine pollution

Marine pollution can be traced again as early on to the Roman times. Industrial waste material, farm runoff and garbage dumping into the oceans have induced much imbalance to the ecosystem in which many organisms thrive in. Despite many work made by eco-friendly organizations and promotions to reduce pollution, it continues to be happening at a big scale.

Pollution is actually the release of harmful contaminants not part of a natural ecosystem. They may add the man-made pollutants like chemicals, pesticide, industrial residue, petrol, sewage, plastics and other solids. These contaminants end up contaminating not only the drinking water in which a lot of the marine life live in however they also result in a disruption in the global food chain. When fish take in these contaminants, humans are all together damaged as they catch and eat the fish. Therefore, radioactive or poisonous contaminants may substantially harm us and as such pollution does affect us up to it can the marine ecosystem.

Excessive pollution may even cause any entire ecosystem to collapse and thus angling may be near impossible once this happens. Seafood can be scarce as an entire food chain will be busted beginning with normal water in the ocean being unsuitable for inhabiting.

Oil spills

Oil spills are usually the most frequent of all marine pollution. A lot of it originates from spillage from large boats and vessels as well as petrol rigs. Furthermore, drainages and rivers also transfer oil into the oceans from metropolitan areas and industry. As oil's density is lesser than normal water, it usually stays on at the surface which in turn causes sea mammals and birds to be afflicted a lot more than fishes as it causes these family pets to perish when they drink this particular or come out to the top to die due to the toxins of the olive oil.

Sewage disposal

Another cause of pollution if sewage disposal. Much urban sewage that is dumped into the sea is untreated or under treated. Sewage alone includes much bacteria and even diseases. Fishes may sometimes eat these sewage and the bacteria will then prosper in them. This impacts us when we capture and later consume the fishes, triggering the bacteria to then be moved into our anatomies. Apart from affecting us in that manner, humans may also be influenced by the diseases in water and beaches closures might occur.

Toxic chemicals

Toxic chemicals make up the majority of marine pollution. Much of these poisonous chemicals are dumped into the oceans intentionally despite much international laws and regulations banning such dumping. Unintentional leakages from establishments also cause these chemicals to disseminate through land, water and through normal water vapour in the air. From the tiniest organisms in the sea such as plankton to much larger animals up the food chain like polar bears. They become afflicted by these chemicals as they are able to travel long distances through currents in the sea. People, who are at the highest end of the meals chain, finish up consuming the best chemical fill as it is multiplied up the food chain.

To conclude, our food is basically reliant on the physical environment so it originates from. Pollution triggers much disarray to the purity and freshness of the food as it influences us directly once we eat them. Fish that has been tainted by toxins from chemicals may cause cancer, harm to immune system systems, behavioral problems, reduced fertility and even death in extreme cases.

Global warming and its results on sea levels

Global warming is causing a drastic problem to humans and their food source likewise, namely seafood, by causing alarming rises in sea levels. The cause of global warming is set up by the greenhouse result. The greenhouse impact is when the sun's heat is caught in the earth's atmosphere when greenhouse gases lead it to be radiated back again to globe. Normally, some heat from the sun is absorbed in to the earth's surface as the leftovers is radiated back to space. When humans melt away fossil fuels like petroleum, gas and coal, they create high amounts of skin tightening and which are the major the different parts of greenhouse gases.

When excessive heating is trapped in the earth's atmosphere, this does cause our earth to heat up beyond normal temperature. This upsurge in temperature is triggering ice caps on Mount Kilimanjaro and glaciers sheets in Antarctica and Greenland to melt. When this happens, normal water levels will grow that may cause many problems that will upset the total amount in nature. Cold water fish will not be able to survive as the would be too warm. This would cause problems for folks doing some fishing them as a food source. Even coral reefs are dying as a result of the increase in water temperatures. Therefore could cause many species of fish who call it home to perish which could in turn affect humans fishing to them. Another great drastic issue is raising normal water levels. Research has shown that low lying countries like the Maldives could be completely submerged should this take place. "Such a growth could have a devastating impact on low-lying island countries, including the Indian Ocean's Maldives, which would be entirely submerged. " (Stefan Lovgren, 2004). Densely populated areas like Nile Delta and Bangladesh would become uninhabitable as well. Not only will fishing be difficult but people will have a greater problem at finding higher floor ideal for living.

An imbalance in nature's food string would be induced by global warming that could drastically affect fishes as food source. As snow sheets melt in the Antarctic, the polar bears living would be adversely afflicted as the temperature would be progressively more too warm to allow them to reside in. "Polar bears are entirely reliant on sea glaciers, you lose sea ice, you lose polar bears. " (Jay Malcolm, 2004). Hence, they might not have the ability to endure and the seal and sea lion human population that would often be manipulated by the polar bears within their diet would multiply and overpopulation may occur resulting in many fishes being consumed and depleted. This depletion would be a negative factor for fisheries and human being civilizations surviving in the northern hemisphere would have to then look for an alternative solution food source which would be difficult as their main source of necessary protein and food are seafood.

Intrusion of sea water

The rise in sea level also contributes to the intrusion of sea drinking water. As the development environment for rice crops is the fresh normal water, the increased salinity in earth can hinder rice development and affect rice production. A report carried out by World Loan provider (2000) indicates that increased salinity by itself from a 0. 3 meter sea level rise will cause a net loss of 0. 5 million metric tons of rice development. Some low-lying deltas (which will be the major rice crops on the planet) of such river systems as the Ganges, the Mekong, the Nile, the Yellow, and so forth, have been affected by tidal influx. 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 debt River Delta of Vietnam.

The release of pesticides

Water in lakes or rivers where in fact the melting glacier moves through can be contaminated with pesticides. Some types of pesticides which contained dangerous elements used to be utilized in agricultural development but they then were banned worldwide years back. Most of the pesticides evaporated in to the air and were finally trapped in layers of glaciers. Now, the fast glacial melting is leading to these unsafe chemicals to be released back into the surroundings, lakes, and rivers. For instance, organochlorine is a kind of pesticide having damaging contents. It had been banned in whole USA because of its bad effects on humans' health like resulting in headache, dizziness, muscle weakness, or even cancer tumor (Delaware Health and Social Services, 2010). This substance, regarding to Blais (2001), shows an increase in one of the sub-alpine lakes in Canada. Such kind of contamination can result in negative influences on the underwater ecology and animals, while at the same time affects the source of normal water used for humans' life as well as farming.

Global Solution

The only way to slow down glaciers melting is to decrease global warming.

The global greenhouse effects requires a global solution, which requires the involvement of the entire global community. (Rogers, 2012) We just have one globe, the protection for this need all citizen be a part of.

Humankind is becoming dependent on burning up fossil fuels to aid our way of life, but it does increase global warming at an unnatural rate. To revive the glaciers we have to utilize alternative energy resources, increase our energy efficiency and lower our specific carbon outcome. (Rae, 2012)

There are a variety of energy available. Solar power panels are made of solar panels that trap the heat from sunlight and convert it into energy. Wind turbines are towers that use the kinetic energy from the wind flow to generate electric power. Biofuels such as ethanol can be produced in your back yard by fermenting and mixing up vegetable, super fruit and grain waste material; ethanol is utilized to make biodiesel gasoline, a clean burning up petrol for diesel engines. Electric vehicles are battery-powered instead of relying of the highly polluting interior combustion engine motor. Tidal and wave power make use of the massive power of the sea by harnessing the with generators placed on the ocean floor. (Rae, 2012)

For individuals, make an effort to take public vehicles instead drive ourself; journey a bicycle if it can help; walk or jog to destination is also a good way to save time and fortify body. Save electricity at home by firmly taking shorter showers, recycling used normal water, turning off electric power for resting tv, computers. Little things can make a large difference if done in a huge scale, and they'll go quite a distance toward minimizing carbon footprint and keeping the glaciers, slow down other effects of global warming.


This report has stated the presently major results that environment designed to the food expansion and supply.

They are the field pollution scheduled to over fertilization, unbalance of marine organism induced 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 matter: "Whenever we see melt in places that we haven't seen before, at least in an extended time frame, it makes you sit up and ask what's taking place. " said NASA chief scientist Waleed Abdalati. "It's a huge signal, this is of which we will sort out for a long time to come. "

It is not only this is the food or the environment that we should think about, but also the connection between. More systematic development have to be considered by administration, organizations and companies.
