Measuring food by the mile How much of your dinner tonight will have been grown locally? And how much will have travelled several hundred miles - even several thousand miles - to reach your table?

Measuring food miles is a complex task but, reports Tim Lobstein, the results make disturbing reading.

Living Earth and The Food Magazine

An analysis of the materials needed to produce our food can be startling. Ten litres of orange juice needs a litre of diesel fuel for processing and transport, and 220 litres of water for irrigaton and washing the fruit. The water may be a renewable resource, but the fuel is not only irreplaceable but is a pollutant, too.
The problem is that fossil fuels, such as petrol and diesel are remarkably cheap. The price of the fuel itself does not reflect the cost of providing the roads on which the vehicles travel. Nor does it reflect the cost of the environmental damage that burning fossil fuel creates. Nor the cost of developing alternatives when the oil wells run dry. All these costs will have to be paid for sooner or later, but they are not added to the price of the food. If they were we might think very differently about whether we wanted to pay the true price for fresh lettuces from California, strawberries from Israel, and flowers from Kenya.

Food Miles Madness

The real cost of food miles madness are seldom reflected in the price of food,' says SAFE Alliance co-ordinator Hugh Raven, 'It costs in terms of diverting land in food-deficit countries from producing food for local consumption into crops for export as with soya production in Brazil. It costs in terms of air pollution and carbon dioxide emissions from air and and road transport. It's madness to fly food halfway around the world when UK growers are going out of business - like the American raspberries on sale in the UK at the height of the raspberry season.
Flying commodites by air, which uses nearly 40 times the amount of fuel that sea transport uses, is now a regular feature of world trade. But cheap fuel can also be used to undercut local suppliers by bringing in commodities from further afield. Take apples. Britain now consumes more French apples than British ones. We have grubbed up over half of our orchards since the 1950s and now bring in apples from Europe, New Zealand, South Africa, Chile and the USA. We could produce many more apples in the UK, benefiting rural communities and saving energy on packaging and transport, but we don't because the big supermarket buyers can get a better deal from the French and the fuel costs are low. For a few pence per pound, the rural economy in Britain is depleted - and the subsequent social and environmental costs of this depletion will then have to be paid for (but of course not by the supermarkets).

Calculating Environmental Costs

Now researchers in Britain and Germany have started to investigate the composite distances travelled by food, taking into account their ingredients and the materials for their packaging. To produce a small glass jar of strawberry yogurt for sale in Stuttgart, strawberries were being transported from Poland to west Germany and then processed into jam to be sent to southern Germany. Yogurt cultures came from north Germany, corn and wheat flour from the Netherlands, sugar beet from east Germany, and the labels and aluminium covers for the jars were being made over 300 km away. Only the glass jar and the milk were produced locally.
In counting the yogurt's environmental costs, the lorry emerged as the main culprit. contributing to noise, danger and pollution. The study found that to bring one lorry-load of yogurt pots to the south German distribution centre a 'theoretical' lorry must be moved a total of 1005 km, using some 400 litres of diesel fuel.
But there are a whole range of further hidden miles that these calculations ignore. To grow the strawberries for the jam for the yogurt, the farmer uses fossil fuels to plant, spray and harvest the fruit, and the sprays he uses have themselves been manufactured and distributed at some environmentat cost. The aluminium for the yogurt jar lids has come from mines many thousands of miles from the packaging plant. Then there is the machinery used for packaging the yogurt, which had to be brought in from Switzerland, perhaps, or Britain, to say nothing of the transport of the workers in the yogurt processing plant going to and from their homes every day. And the transport of shoppers from their homes to the shops, in order to buy the yogurt.. So the circle widens, at every point adding to the real costs of the yogurt, but which do not get added to the price and instead must be paid for in other ways at other times.
|Food miles are big in the food aisles. |
|In early September, home-grown seasonal fruit and vegetables like apples, onions, carrots and green beans were available |
|throughout the country. But so too, in three central London supermarkets, were apples 4,700 miles from the USA, onions over 12,000|
|miles from Australia and New Zealand, carrots from South Africa (51,000 miles) and beans from Kenya (3,600miles). |

And then there is the question of the true cost of meat, and the vast tracts of land devoted to the growing of feedstuffs for rearing animals. This land is referred to in the British study of food miles (published by the SAFE Alliance) as 'ghost acres'.

Ghost Acres

These include some 44 million ghost acres in Thailand alone (ie an area about the size of Ireland) devoted to supplying manioc for European cattle. Export commodities such as these distort a developing country's agricultural economy, encouraging small farmers to participate in growing cash crops for export rather than food crops for local needs. Brazil has become a major supplier of soya beans for European animal feed, but to do this it has to cut down a quarter of its Cerrada plateau forest, some 12 million acres, causing immeasurable damage.
These are typical of the ghost acres, the distant, blighted areas of the world being exploited to satisfy European demands for meat and meat products. In the UK we exploit two of these ghost acres abroad for every one acre we farm at home. We can do this only because the true costs of exploiting Brazil and Thailand, and the true costs of shipping the animal feed to Europe, are not reflected in the price of the food consumers buy.
|Both the SAFE report and the one from Wuppertal, Germany, call for more realistic fuel pricing policies through the introduction |
|of a targeted fuel tax. They also urge manufacturers and retailers to review their purchasing policies in order to give greater |
|priority to local producers. |

The Category 5 hurricane terrorizing all cities and states on its war path of destruction; Katrina is what they call her and her storm surge reached 20 feet high. 1,836 was the final death toll that Hurricane Katrina caused and her affects were impacted over approximately 90,000 square miles. 80% of New Orleans was underwater and some places were up to 20 feet under. (11 Facts About Hurricane Katrina) This destruction is unimaginable to most of us but for those that experienced it, it is something they never want to experience again. Along Katrina’s route of destruction, tornados were developed wreaking havoc in other states. In this paper I will discuss, in depth, hurricanes and tornados and the destruction they cause to our nation.

The accurate definition of a hurricane is a “tropical cyclone with sustained winds that have reached speeds of 74 mph or higher” the storms are labeled as hurricanes when they gain their strength over days and weeks time.

Sustainability maintained or to sustain itself. It’s about taking what we need to live now, without jeopardizing the potential for people in the future to meet their needs (“What”). If an activity is said to be sustainable, it should be able to continue forever. Some people say it is easy to recognize activities that are unsustainable because we know it when we see it. Think of extinction of some species of animals, often due to the activities of humans. Or salt in our rivers due to changed land management practices. And at home, the amount of packaging you put in the bin that has to go into landfill. In addition to these, sustainability can be measured in things like our energy use and carbon footprint, solid waste generation, and even our food choices. Measuring your energy use and carbon footprint is something that every American needs to take time to do. This is very important because it puts in perspective how many Earth’s we would need to support human life if everyone lived like you. For most Americans, the results are shocking. Our class took a survey to determine our carbon footprint. The average number of Earth’s it would take to support our class was 5.5. When looking at home energy use, our class currently averages over 10,000 lbs of CO2 emissions per year; but we can collectively reduce our carbon emissions by an average of 12%, providing us with an average of over $700 per year.

The southeast trade winds blow from the southeast toward the equator, rather than away from the equator which the northern hemisphere. The southern equivalent of the horse latitudes is called the Variables of Capricorn. The southern westerlies start barely south of South Africa. They are stronger than the northern westerlies because they occur over majority water (roaring forties). On the other hand, the southern polar easterlies are mostly over Antarctica. Question 2: Some years ago I travelled in South America on a trip arranged by our government and the host countries governments. We spent some time driving on a highway that ran along the Pacific Ocean. Every fifty miles or so if I remember it correctly-we had to stop because road graders were moving large drifts of sand from the road.

This was a contrast, because we had been on the other side of the Andes a short time before where it was tropical rain forest. Would what I just described have a connection to Question 1? Yes, the above description would connect with question 1. It connects because winds follow as the earth rotates. Also, the prevailing winds are stronger in the southern hemisphere, due to the abundance of bodies of water, which is where South America is located.

Cost Accounting Chapter 1

...CHAPTER 1 The Changing Role of Managerial Accounting in a Dynamic Business Environment ANSWERS TO REVIEW QUESTIONS 1-1 The explosion in e-commerce will affect managerial accounting in significant ways. One effect will be a drastic reduction in paper work. Millions of transactions between businesses will be conducted electronically with no hard-copy documentation. Along with this method of communicating for business transactions comes the very significant issue of information security. Businesses need to find ways to protect confidential information in their own computers, while at the same time sharing the information necessary to complete transactions. Another effect of e-commerce is the dramatically increased speed with which business transactions can be conducted. In addition to these business-to-business transactional issues, there will be dramatic changes in the way managerial accounting procedures are carried out, one example being e-budgeting, which is the enterprise-wide and electronic completion of a company’s budgeting process. 2.

...basal metabolic rate (BMR) calculator, where you can enter your numbers. This tool measures how many calories you need each day to maintain your current weight if you’re sitting around doing absolutely nothing—and how many you need if you’re more active. Once you know how many calories you need to maintain your weight, you can make some well-informed decisions about the food you’re consuming and your exercise. You can eat less or move more to get the scale to move, too. n Calorie Math: A Quick Review Let’s strip this idea down to the simplest possible terms. Your body burns calories every day. If you eat more calories than your body burns, those calories are stored on the body as fat. If you eat fewer calories than your body burns, you lose fat. In other words, a calorie deficit is what leads to weight loss. H ow much of a deficit do you need to create? Well, a pound is 3,500 calories. So if you want to lose a pound in a week, you need to have a deficit of 500 calories per day.

...of polarization states of light. ScienceDaily. Large-scale surveying & mapping problems are also key challenges in making direct Measurements in astronomy. Pogge R.(2006) One of the indirect forms that the scientists have used is to resort to GEOMETRY to find the Distance. Parallax is one of the indirect methods where astronomers can measure the position of a nearby star very carefully with respect to more distant stars behind it, then measuring those distances again six months later when the Earth is on the opposite side of its orbit. Allen J.,Boyd P. (1997,April 15) The limitation of parallax is that it just gives distances to stars tp up to a few thousand light Years and beyond those distances, parallax are so small that they cannot be measured by Contemporary instruments. The methods used beyond light years are Stellar motions: All stars are in motion, but only for nearby stars are these motions perceivable. Statistically, therefore, the stars that have larger motions are nearer. By measuring the motions of a large number of stars, we can estimate their average...

Following that massive earthquake was second and even more destructive force, a tsunami causing massive and irremediable damage to the nuclear reactors of a nuclear power plant called Fukushima, which released harmful radiation elements and substances into the environment. The tsunami devastated Aomori an area located about 30 miles east of City of Tokyo. The devastating and far reaching results of this earthquake and tsunami included: * Approximately 20,000 people were killed * Approximately 750,000 homes were destroyed and vanished * The industrial facilities of this region which were extensive and included production plants for the steel industry, consumer electronics, automotive industrial parks, and petrochemicals plants * And arguably the most long term devastation came from the leakage of nuclear material from the Fukushima Nuclear Power Plan The International Nuclear Event Scale (INES) ranked the disaster of the Fukushima Nuclear Power Plant at a level 7.
