Or at least for seven generations (roughly 200 years). Leading scientific societies say that the future promises irreversible environmental degradation and continued poverty for much of the world unless we control human population and change patterns of human activity. "The future of our planet is in the balance," said a 1992 statement issued jointly by the Royal Society of London and the U.S. National Academy of Sciences. "The next 30 years may be crucial," these scientific societies said 7 years ago. Task N°1: Make a list of the keywords related to “A sustainable use of the Earth (1)”. Then check with your partner. Task N° 2: complete What is: a sustainable activity? What is: a main risk for the future? What is: a possible solution for the future of Earth? Task N°3: Answer true or false to the following statements. If they are false, correct them. 1. A sustainable activity can continue for about 200 years. T-F 2. There will be poverty and degradation in much of the world in the future. T-F 3. It is necessary to control human population if we want to protect the future of our world. T-F 4. The next 7 years will be crucial for the future of the world. T-F 5. Some models of the human activity must be changed to stop degradation and poverty. T-F TASK N°4: Which of the following words and phrases refer to the text you have just read? EARTH DANGER DESERTIFICATION NATURAL HERITAGE RESPECT ECOLOGICAL-SYSTEM RESPONSIBILITY DAMAGE DESTRUCTION A sustainable use of the Earth (2) Nella figura sono rappresentate graficamente le variazioni previste per la metà di questo secolo nelle temperature medie annuali. Le variazioni sono ipotizzate sulla base dei valori di temperatura odierni nel caso in cui vi sia un aumento totale nelle concentrazioni atmosferiche dei gas serra equivalente ad un aumento annuo di anidride carbonica dell'1%.

As the 1992 joint statement said, "Developed countries, with 85 percent of the world's gross national product and 23 percent of its population, account for the majority of mineral and fossil-fuel consumption. One issue alone, the increases in atmospheric carbon dioxide, has the potential for altering global climate with significant consequences for all countries. The prosperity and technology of the developed countries, however, give them the greater possibilities and the greater responsibility for addressing environmental TASK N°5 Fill in the text with the following words: 1992 CLIMATE “DEVELOPED” PROBLEMS 85 AND COUNTRIES DIOXIDE MAJORITY PRODUCT THE It is particularly important that the so-called ........... countries change their ways.

A group of Swedish scientists has described 4 conditions that are essential for sustainable use of the Earth. A worldwide movement, called The Natural Step, is promoting these four conditions, especially among business organizations. The four "system conditions" necessary for sustainability are stated succinctly in the following slides. Condition n°1 Substances mined from the Earth's crust must not systematically increase in air, water, soil, or living things. This means that fossil fuels and metals must not be produced at a faster pace than their slow redeposit and reintegration into the Earth's crust. Condition n°2 Substances created by humans must not systematically increase in air, water, soil, or living things. This means that substances must not be produced at a faster pace than they can be broken down and integrated back into the cycles of nature. Condition n°3 The physical basis for productivity and diversity of nature must not be systematically diminished. This means that we cannot harvest or manipulate ecosystems in such a way that their productivity and diversity are systematically diminished. Condition n°4 There must be a fair and efficient use of resources in meeting human needs. This means that basic human needs must be met efficiently, effectively, and fairly; it also means that the satisfaction of basic human needs must take precedence over the provision of luxuries. TASK N°7 Complete the following sentences: 1) Substances mined from the Earth’s crust must not ……………… too fast in environment. 2) Substances created by humans must not …………….. too fast in the envinronment. 3) Diversity of nature must not be ……………………in ecosystems. 4) There must be an efficient use of …………………. in meeting human needs. TASK N° 8 Match the following short definitions and one of the 4 system conditions necessary for sustainibility: A) use of fossil coal B) protection of dolphins 1) Substances mined from the Earth's crust must not systematically increase in air, water, soil, or living things. 2) Substances created by humans must not systematically increase in air, water, soil, or living things. C) protection of drinking water D) production of plastics E) controled use of petroleum F) respect for state health G) respect for biodiversity H) production of pesticides 3) The physical basis for productivity and diversity of nature must not be systematically diminished. 4) There must be a fair and efficient use of resources in meeting human needs. TASK N°9 Working in 4 groups, try to relate your everyday life to one of the four conditions for sustainable use of the Earth. At the end, each group will present the result of the task in plenary. My everyday life and sustainibility ___________________________ ___________________________ ___________________________ ___________________________ Agenda 21 Agenda 21 is a comprehensive plan of action to be taken globally, nationally and locally by organizations of the United Nations System, Governments, and Major Groups in every area in which human impacts on the environment. Agenda 21, the Rio Declaration on Environment and Development, and the Statement of principles for the Sustainable Management of Forests were adopted by more than 178 Governments at the United Nations Conference on Environment and Development (UNCED) held in Rio de Janerio, Brazil, 3 to 14 June 1992. The Commission on Sustainable Development (CSD) was created in December 1992 to monitor and report on implementation of the agreements at the local, national, regional and international levels. The full implementation of Agenda 21 was strongly reaffirmed at the World Summit on Sustainable Development held in Johannesburg, South Africa from 26 August to 4 September 2002. AGENDA 21 PROGRAMME There are common factors, which it was clear from the beginning should be present in any Local Agenda 21 process: It's not just an environmental strategy. Integrated sustainability plans have to consider social and economic issues too. It should involve the whole community - or at least the widest cross-section possible with the resources available. It should build consensus - bringing people together instead of the old, confrontational ways of working. The first step is to gather information about local conditions and priorities - finding out what people are really concerned about. Then, actions can be identified. No organisation or sector of the community has a monopoly on good ideas. It's important to find ways of measuring progress so we can be sure our actions are working. Task n°10 On december the third in our school we will take part in a conference about Local Agenda 21 in Gorizia. Listen what the experts will say and write a short report in English. Please, explain which are the most important factors that people in Gorizia can do to promote a sustainable use of local environment. Ecological footprint (1) The simplest way to define ecological footprint would be to call it the impact of human activities measured in terms of the area of biologically productive land and water required to produce the goods consumed and to assimilate the wastes generated. More simply, it is the amount of the environment necessary to produce the goods and services necessary to support a particular lifestyle. TASKS N° 11 AND 12 Using old newspapers draw a large footprint and use it as a poster: write inside a short sentence or a nice slogan for promoting sustainibility. Use computer and search in Internet the site: http://www.earthday.net/footprint /index.asp Here you can answer to the ecological footprint quiz. At the end write your personal footprint in the poster done at task n°11.

At the end write your personal footprint in the poster done at task n°11. Ecological footprint (2) Humanity's Footprint Today, humanity's Ecological Footprint is already over 30 percent larger than what the world can offer. This means we are overusing the planet and liquidating its ecological assets. Examples of our overuse include deforestation, collapsing fisheries, and the build-up of heat-trapping carbon in the atmosphere. At the same time, a significant percentage of the world's people do not have enough resources to meet basic survival needs. TASK N°13 As you can see in the graph, the ecological footprint in the world is increasing: can you explain why?
