ASSIGNMENT  2










    Introduction

         In the "Story of Stuff"(2007) video, Annie Leonard talks about the materials economy, the system of this planet to extract all the necessary materials for the industry is not any fair for all. We use energy for the addition of chemicals toxins to the natural resources that results in health problems and pollution. Also, this means to participate in the distribution with some companies at a low cost to keep prices down to the calibration costs. Some governments have tended to use the political commercials to make the citizens shop a lot. You should face the problem of accumulated waste material produced so you should recycle and use less stuff in general. For example, replacement of old, for new engines.









ASSIGNMENT 2

            In our days , having such a great and easy life means having more facilities by using different kinds of stuff which basically means new products and goods , whether these things were natural or manmade stuff. Many new inventions and products came up within the last century's; these things didn’t come from nowhere! These all are from nature and man reproduce them by adding things together to come up with them. Several steps the sources of nature have been gone through to extract new useful products that serve humans in these days. The steps are: extraction, production, distribution, consumption, and disposal.

            Extraction of natural resources in our planet means cutting all of the trees to use the wood, digging the mountains for different kind of material, using water and killing animals for their skin and teeth and whatever is useful for human. Doing all such things will make our planet lose the balance, which already is been effected due to all of the extraction works. Forests are affected, a desert was polluted, water was polluted too and animal got killed. We are losing our recourse.

        "An ore is any naturally-occurring source of a metal that you can economically extract the metal from. Aluminum, for example, is the most common metal in the Earth's crust, occurring in all sorts of minerals. However, it isn't economically worthwhile to extract it from most of these minerals. Instead, the usual ore of aluminum is bauxite - which contains from 50 - 70% of aluminum oxide" (Clark 2005).



           After all these natural recourse have been extracted they are moved to production. The word production by itself means to reproduce the natural sources by adding chemicals to it. These chemical most of the times are considered to be very toxic and harmful to human. So what production basically means is adding toxics to materials to produce toxic which we use are daily basis.  This production step will pollute the air, the sea water too. This means raising the pollution level in our planet.

       "The U.S. could add nearly 1.5 million jobs if it adopted a 75% national recycling rate. Wow, that’s a lot of jobs! Instead of propping up the dinosaur economy highlighted in The Story of Broke, we can be investing in more jobs and a healthier future by keeping the stuff we use in our economy, instead of dumping or burning it" (Allison, Cook, 2011)



          What happens after the production step , is that these new material needs to sell out to consumers which means distributing all the materials  with a cheap price to keep people buying all the time as quickly as possible. This will definitely create greater environmental impact, and more energy will be used to transport these goods to the consumers.

           These goods and materials are now being consumed by people, as more people consume materials and goods more trash is there, everything man uses is turning to trash. As the stuff get newer version, people keep buying more and more. This is a way that the producer uses to sell more and keep people buying more. Advertisements has a great rule in making people buy all the time, the media rule is one of the reasons behind making people go shopping to consume more.

       "For holidays tainted by commercialism, Valentine’s Day gives Christmas a run for the money – big money. The National Retail Federation estimates Americans will spend $17.6 billion on Valentine’s gifts this year, including $4.1 billion on jewelry, $1.8 billion on flowers and $1.5 billion on candy. But for consumers with a conscience, the very things Madison Avenue markets as expressions of love are some of the worst stuff you can buy" ( Leonard in Cook,2012)



          After consuming, much waste and trash are created, man can’t keep the trash in his house, that is why there is this step after consumption which is called disposal, In disposal all the trash is being burned or buried under ground or thrown to the sea to get rid of them, All of these ways are causing harm to the plant, to the air, water we drink and food we eat and climate.

         The United Arab Emirates is now considered to be a high-level economic country with various production, which means that we produce materials and goods. Dubal is one of largest companies in Dubai which produces aluminum, to produce these huge amount of aluminum it passes through all the previous steps mentioned before, starting with the extraction of the metals from the mountains, and then to the factories which needs lots and lots of energy to melt the aluminum to shape it for consumers and then to disposal or recycling.

       "From time immemorial, waste disposable has been a problem, and after industrialization the problem has only compounded. In the past, trash was carried to the outskirts of cities and discarded in the open, but now that can no longer be done. Over time, various waste disposal methods have been devised, like compost, burning, landfill, biological reprocessing, etc. However, before going to these details, we need to understand the different kinds of wastes. There are basically three types of wastes generated - solid waste, liquid waste and sludge. They are classified as per their chemical, biological and physical characteristics" (Bhattacharyya, in Cook, 2012)



          This cycle is harmful to the environment it causes high levels of pollution, greenhouses gases which effects the global warming and the ozone. That is why people and governments need to take care of these issues rapidly.

         Here in UAE the government is trying to reduce the harms of pollution in the environment by putting some restrictions for factories, and prohibiting people from throwing the garbage in the sea in order not to affect the sea life since the UAE population depends on the sea as numbers one of our natural sources. And now they have started to use renewable energy sources to reduce greenhouse gasses to reduce this problem.

        Planet earth natural sources doesn’t belong to us only, it belongs to all living creature whether they were animals or plants, we should respect this, and keep the balance in the environment, we should not play with it, because any change in the balance will finally affect us because we all live in a big chain we all are related so the harm will end up coming to us.

Hybrid Car
 
           The Hybrid Cars are type of cars that uses distinct power sources to move them, the most common used term for the hybrid cars are the Electric hybrids cars which mainly uses an engine and electrical motors. There are two types of the electrical hybrid cars which are the parallel hybrid cars which use either the electric motor or gasoline engine to turn the transmission, and the series hybrid car which only has the electric motor which is directly connected to the transmission, The gasoline engine is used for charging the batteries that are used to charge the electrical motor.
          In the early days of the 17th century a Jesuit priest named by Ferdinand Vebiest started working on the hybrid vehicle, this was the first type in the world of hybrid cars. At first he started his plans to begin working on a simple 4-wheel vehicle that could run on steam. Although he spent around 15 years there were no evidence that hybrid cars ever came to exist. Later on by the 18th century came a person named by Nicholas Cugnot came out with a steamed carriage, he did all the needed drawings and came up with a vehicle that could move at a speed of 6 miles per hour. Personally I consider this to be a big step in hybrid car inventions, but the big problem was that it was really hard to maintain enough steam to travel any real distance, so people considered this to be not very successful project. In the 19th century the efforts started in Scotland by Robert Anderson where the first electrical powered car was created. This vehicle had limited range and the battery power was very difficult to recharge. And by 1870 a lighter motor was invented by Sir David Solomon, and the battery was a problem too.
        The developments came in the 20th century and basically in 1900 when an employee at the Lonher Coach factory named by Ferdinand Porsche developed 4 wheel hybrid vehicle named by the (MIXTE), it included a pair of generators driven by an engine and it could travel for 65km on batteries. This MIXTE broke several records and won several awards. The MIXTE used a gasoline engine which was powering a generator. It had a top speed of 50km/hr. later on 1902 came George Fischer from England producing a Racing Hybrid. More and more trails came in the 20th century to develop the hybrid car.
      Modern developments accrue in the 21st century where several companies such as: Toyota, Honda and Ford and more over started to develop their own designs of hybrid cars and the release them to the markets. More than 4.5 million hybrid electric vehicles have been sold worldwide by the end of December 2011.The latest hybrid car was released in 2012 by Volkswagen is working by diesel –electric hybrid and gasoline-electric hybrid car. There are also new hybrids cars are scheduled to be released within 2012 from the following companies (Audi – BMW – Ford and Volkswagen).
      In conclusion I would like to write that people are becoming more and more interested in the new hybrid cars that are coming out every year. People love them because they are more environmental friendly and can offer longer rides; also they have excellent performance capabilities and can operate like the gasoline powered cars. Maybe in the future people will stop using the normal cars because on the environment pollution issue and the hybrid cars will be used widely.

         "If you think hybrid-electric vehicles are a 21st Century exclusive, think again. General Motors showed off (working!) hybrid prototypes in the 1960s and the technology was already more than 60 years old! Take a trip with me, into the forgotten history of hybrid cars" (Borras, J. (2010, September 8(
