UNIT 1: Environmental consciousness Topic 1: sustainable development and environmental problems In this unit, we will learn about major environmental expressions and definitions, and sustainable development. Exercise 1. Major vocabulary Match the following expressions/words with the pictures from the slide show: acid rain, sewage, water pollution, exhaust gas, CO2 emission, air pollution, renewable energy, wind power, solar power, desertification, deforestation, the great chain of living, selective waste collection SLIDE 1 Source:http://www.flickr.com/ SLIDE 2 Source:http://www.flickr.com/ SLIDE 3 Source: http://www.flickr.com/ PETRIK TISZK TÁMOP-2.2.3-07/1-2F-2008-0011 9

Sustainable development Read the text. Then find the answers to the questions below. Sustainability means the capacity to endure. In ecology the word describes how biological systems remain diverse and productive as time passes. Sustainable development means that we should use natural resources wisely in order to preserve the environment for our wellbeing and that of future generations. The most often quoted definition of sustainable development as development that meets the needs of the present without compromising the ability of future generations to meet their own needs. This means that if we don t take enough care of the environment today, we will cause serious damages for our children and grandchildren. 10 angol nyelv tanulói jegyzet 11. évfolyam
1. What does sustainability describe in ecology? 2. What should we, humans do for sustainable development? 3. What will happen to future generations if we don t take enough care of the environment? Exercise 3. Different forms of pollution a) Read the definitions of different pollution factors that set back sustainable development. Fill in the gaps. Use the following words: air pollution, global warming, deforestation, water pollution, erosion, the great chain of living, CO2, burned, wildlife Source: http://www.flickr.com (1) means the introduction of chemicals or biological materials into the atmosphere which has a harmful effect on the natural environment. It is often caused by the exhaust gas of cars, industrial smoke, or fly ash generated by thermal power plants. PETRIK TISZK TÁMOP-2.2.3-07/1-2F-2008-0011 11
Exhaust gas coming from cars contains CO2, one of the most important greenhouse gases. CO2 emission causes the so called greenhouse effect, which is responsible for (2)., the increase of average world temperatures. Global warming could have disastrous consequences from species disappearing to polar ice melting and floods. As trees grow, they absorb (3), but when they are cut down, CO2 remains in the air. Forest clearance, wood burning or in other words (4). is now out of control. For example in 1987 an area of the Amazon rain forest the size of Britain was (5)., adding 500 million tonnes of CO2 to the atmosphere. It is also a major problem for (6) in the area because they lose their habitat, homes, hiding places and food source. It also alters the great chain of living endangering certain species. As a result, (7) often appears in such areas as wind or water wears away land surface. (8) can be caused in many ways for example by sewage let into rivers or seas, damaged, leaking oil tankers, or industrial waste. It has a dangerous effect on (9) because seabirds eat poisoned fish. b) Do you know any solutions to these problems?............... c) Put the second part of the text in order. a) b) c) Another thing we can do is selective waste collection, which means that we collect our waste so that we separate paper, glass, plastic and metal and then we take it to the selective waste collectors. Instead of going everywhere by car, we can walk, bike or use public transport. And last but not least we can walk, bike or use public transport. Instead of using fossil fuels, which the planet will run out of soon, we should use renewable energy such as wind or solar energy. The first step towards the solution is being environmentally conscious. This simply means that we care for the environment, for example we carefully consider that the products we buy in shops are produced and packed in an environmentally friendly way. 12 angol nyelv tanulói jegyzet 11. évfolyam

Topic 2: Global warming In this unit, we will learn about global warming and find its causes, effects and possible solutions. Exercise 1. Revision of environmental problems Your teacher will read you some environmental problems. Write them down. Then write down its causes, consequences and possible solutions. Environmental problem Causes Consequences Possible solutions Exercise 2. Global warming greenhouse effect climate change Read the text. Then answer the questions below. Global warming is the result of greenhouse effect. The so called greenhouse gases, such as carbon dioxide (CO2) in the atmosphere act like glass in a greenhouse, and allow sunlight through to heat the earth s surface but trap the heat as it radiates back into space. As the greenhouse gases build up in the atmosphere the Earth gets hotter. Trees breathe in carbon dioxide and store the carbon in their trunks. When the wood is cut down the CO2 is returned to the air. This way, forest clearance and wood burning adds to the CO2 in the atmosphere, but the loss of the forests also means that there are fewer trees to absorb CO2. Deforestation causes less than half the yearly total of CO2, the rest comes from the burning of coal, oil and other fossil fuels. These fossil fuels are needed in cars, power stations and factories. Every time we switch on a light we are adding to the greenhouse effect. Cars are also major sources of CO2. The average European is responsible for nearly 2.5 times as much atmospheric carbon as a Latin American. The concentration of CO2 has increased 25% since the industrial revolution, half of this rise has been in the last 30 years. It is expected to double within decades. PETRIK TISZK TÁMOP-2.2.3-07/1-2F-2008-0011 15
The warming of the planet is changing the world s weather patterns which is why we call it climate change. Unless we stop it, it will have disastrous effects: if polar ice melts, it will endanger species such as polar bears and many others. The melted ice will cause floods and as a result, entire cities might disappear, among others, a huge downtown area of New York City. Changing temperatures alter the great chain of living because animals and plants rely on each other. Also, it has an effect on the big ocean currents which might alter their patterns. Scientists say that as a result of that, another ice age might occur! 1. Explain the greenhouse effect. 2. How do trees help eliminate the greenhouse effect? 3. What are the main sources of CO2 emission? 4. How do we add to global warming? 16 angol nyelv tanulói jegyzet 11. évfolyam

Topic 3: selective waste collection In this unit, we will learn about different types of waste, the 3R concept and some examples brought from the European Union. Exercise 1. Waste types and recycle centers On the left, you find different types of waste. On the right, places where you can take or recycle them. Match these two. Sometimes more than one solution is possible. Paper a) Selective waste bins Plastic pet bottles b) Composter Metal drinking cans c) Schools, public institutions Electrical appliances d) selective waste collection yards White and coloured glass e) Selective waste collection islands Fruit/vegetable skin, garden waste Light bulbs, neon tubes Dry cell batteries Cell phones Exercise 2. The 3R concept Read the text then answer the question below. f) Shops which sell them We produce more rubbish today than ever before, on average each household in Budapest produces about half a tonne of waste every year. Much of this waste contains potentially useful materials such as paper and plastic, glass and metals which could be recycled, reducing the amount of rubbish, creating less pollution and saving energy. The 3R concept is Reduce, Reuse, Recycle. Reduce means of course that first of all we should lessen the amount of waste. Reuse is to use an item more than once. This includes conventional reuse where the item is used again for the same function, and new life reuse where it is used for a new function. In contrast, recycling is the breaking down of the used item into raw materials which are used to make new items. By taking useful products and exchanging them, without reprocessing, reuse help us save time, money, energy and resources. 1. How much waste does a family produce in Budapest? PETRIK TISZK TÁMOP-2.2.3-07/1-2F-2008-0011 19
2. What is the 3R concept? Explain it with your own words. 3. What is the difference between reuse and recycle? Exercise 3. A European environmental school project The following description of an environmental project comes from The European Environmental Agency. They collect success stories on waste prevention from the European Union. The text below is one of them. Read it carefully then do the exercise. Title Objective Description Sensitization project for schools Stimulate pupils to buy environment friendly school materials that are durable, healthy, made of recycled materials and create less waste. In a folder the pupils and their parents get 12 hints on how to buy environment friendly materials. Teachers receive an educational file with information and hints on how to prevent waste, shopkeepers promote environment friendly school materials with promotional posters. In 2003 150,000 folders were distributed in Flemish schools You can find the rest of the success stories here: http://scp.eionet.europa.eu/facts/wastebase/prevention/ index_html Make a list of actions that were taken to reduce the amount of waste. a) b) c) 20 angol nyelv tanulói jegyzet 11. évfolyam

Group 1. Title Field of application Waste type Country Objective Recycle centres Institution building, Repair share reuse Municipal, Commercial, Household Belgium The mission of the recycle centres is, A) to promote the re use of household materials, such as furniture, household appliances and clothes, B) to offer jobs to semi and unskilled workers and to the long term unemployed, C) to sell high quality second hand goods at low prices to fight poverty. Description Almost 40 recycle centres have been set up in different towns in Flanders. They collect second hand goods usually by picking them up on demand or people deliver the goods at the centre. Goods are repaired in re use centres and sold again in more than 90 recycle shops. Target group Households Achievements In 2001 more than 20,000 tonnes of goods were collected which means 3.5 kilograms per inhabitant. Around 70% of the collected goods were reused. Evaluation The recycle centres reduce the amount of waste and give jobs to the unemployed. They produce high quality second hand articles. PETRIK TISZK TÁMOP-2.2.3-07/1-2F-2008-0011 23
Group 2. Title Field of application Waste type Target group Country Objective Ecomoebel Repair share reuse Bulky Furniture users, waste management organizations, local authority associations, handicraftsmen (carpenters, restorers, cushion makers, artists), designers. Germany The quantity of used furniture is growing rapidly. Disposal and burning is a burden to the environment and it means additional costs for consumers. The project is trying to solve this problem and provide new employment opportunities. Description Ecomoebel is the name of an innovative network for the reconditioning and marketing of used furniture. Its network has many partners, e.g. handicraftsmen (carpenters, restorers, etc), artists, and designers, marketing and computer professionals. There are high quality standards for the refurbishment of used furniture. All furniture is analysed for harmful substances and restored with environmentally friendly products. The customer receives all information about the restoration. This certificate is the basis of the ecomoebel quality signet, which guarantees a low polluted furniture with a high quality standard. Achievements In Germany about seven million tonnes of furniture are thrown away every year. Around 5 % of this quantity is reused. It is estimated that the quantity of reused furniture can be increased from 5% to 6, 7 or 8%. Evaluation The ecomoebel network creates jobs and qualifies the persons employed at the refurbishment enterprises. Ecomoebel provides benefits for all participants in the furniture life cycle. Customers can buy high quality furniture while reducing the amount of waste. References http://www.ecomoebel.de/ Try to think of possible solutions to common environmental problems.

topic 5: the ecological footprint In this unit, we will learn about the ecological backpack and the ecological footprint. We will try to compare products from this aspect. Exercise 1. Let s buy the least polluting You would like to buy environmentally friendly products in a shop. Which of these items would you buy? Can you say why? Fresh pizza Sliced, deep frozen German bread in an aluminium foil Apples from Hungary Austrian milk in a box Deep frozen pizza packed in a plastic bag and a paper box Fresh potatoes Spanish strawberries in a plastic box Hungarian eggs Sliced, deep frozen, ready to fry potatoes in a plastic bag I would buy:............... I would not buy:............... 26 angol nyelv tanulói jegyzet 11. évfolyam
Exercise 2. The ecological backpack Read the text. Then answer the questions below. The ecological backpack method is used to measure the total amount of natural resources required to produce and transport a given product or service. It tries to reveal the material used during the production or transportation phase but which is not visible in the final product. The ecological backpack can be measured in five categories: abiotic (non renewable) and biotic (renewable) resources, erosion, water and air. For example the weight of a non renewable ecological backpack of a computer is more than 1 400 kilograms. Its physical weight is only about 25 kilograms which indicates that somewhere in the world large amount of resources have been transferred or used. This can include energy use, processes and side products in raw material production. 1. What do we use the ecological backpack method for? 2. What does it try to reveal? PETRIK TISZK TÁMOP-2.2.3-07/1-2F-2008-0011 27
Exercise 3. Factors of the ecological backpack Take a look at the products from the first exercise. Discuss what you think about their ecological backpacks. Make a list about the factors that make their backpacks big. The first one is done for you. Give ideas about how to reduce their backpacks. Name of the product Sliced, deep frozen German bread in an aluminium foil Deep frozen pizza packed in a plastic bag and a paper box Austrian milk in a box Spanish strawberries in a plastic box Sliced, deep frozen, ready to fry potatoes in a plastic bag Factors of its ecological backpack it is sliced (used energy) it is deep frozen (uses electricity) it was transported from Germany (used fuel) it is packed in an aluminium foil (produced from raw materials with energy) it generates a lot of waste and CO2 emission How could we reduce it? it shouldn t be sliced it shouldn t be deep frozen it should be transported from the closest bakery in Hungary it should be wrapped in paper 28 angol nyelv tanulói jegyzet 11. évfolyam
Exercise 4. About the ecological footprint Do you know what ecological footprint is? Read the text below. Then discuss the questions below. The ecological footprint measures the amount of biologically productive land and sea area which we need to live our everyday lives. It includes for example the production, transportation and storage of all the things we buy and the services we use. The calculated amount of land and water means the resources a human population consumes and also which absorb waste. Thus in fact it compares human demand with planet Earth s ecological capacity to regenerate. It can be calculated for individuals, communities, countries or the entire planet. In 2005, humanity s total ecological footprint was estimated at 1.3 planet Earths in other words, humanity uses ecological services 1.3 times as fast as Earth can renew them. 1. How does ecological footprint calculate our impact on planet Earth? 2. Do you think there is a difference between the ecological footprint of countries/continents? Why? 3. How can we reduce our ecological footprint? Make a list. 1.... 2.... 3.... 4.... 5.... 6.... PETRIK TISZK TÁMOP-2.2.3-07/1-2F-2008-0011 29
