Nuclear /other resources 1. (a) Explain which type of energy production you consider to have (i) the least, and (ii) the greatest, environmental impact.  (b) Choose one scheme which exists to supply energy. Explain the attitudes of different groups of people to the scheme and any disagreements or conflicts of interest which have occurred.  (a) Outline some of the arguments for and against hydro-electric power (HEP) as a source of energy.  (b) With reference to one country, in what ways could its energy strategy be said to have failed?  Outline the main arguments for nuclear power. Explain some of the issues in the production of electrical energy in one country you have studied. To what extent can the production of electrical energy there be considered sustainable?
Rural degradation 2. (i) Give the meaning of the term soil erosion and explain why soil erosion concerns farmers.  (ii) Using examples, describe and explain how soil erosion may be minimised in either arable farming or pastoral farming.  (b) Assess the importance of the government’s role in bringing agricultural change to one country you have studied.  With the help of examples, explain how three different factors may contribute to the degradation of rural environments.
<ul><li>12 (a) (i) </li></ul><ul><li>pollution is contamination 1 </li></ul><ul><li>of the terrestrial environment, earth or land surface 1 </li></ul><ul><li>by people disposing of waste or by waste or substances or materials 1 </li></ul><ul><li>'in the wrong place, at the wrong time, in the wrong amounts and in the </li></ul><ul><li>wrong chemical or physical form' (Small and Witherick). 3 </li></ul>(ii) Credit 2 each of two instances of action and materials, e.g. dumping of spoil from mining; fly-tipping of domestic rubbish; littering the streets with newspaper, cigarette ends, drinks cans, food wrappings. 4 (iii) More demanding. Burning/combustion/incineration is one alternative, others are from the "recover, reuse, recycle" trio: e.g. recovering usable materials such as textiles; composting green matter; recycling paper. Credit 1/2 or 2/1. Do not credit dumping at sea as it is cannot be seen as environmentallyfriendly or safer. 3
