30. 08/27/10 06:16 The predicted impacts of global warming on the world. Permafrost ground will melt, causing massive landslides. Oil pipelines, houses and road foundations will be disintegrated Arctic ice cap melts. Rising temperatures worldwide would cause ski resorts to be wrecked as heat will melt the snow & ice there. Forests are damaged by heat and drought Bangladesh is already prone to flooding, so rising water levels could devastate the country . Water shortages in the Middle East would cause the River Nile to dry up due to intense evaporation. Mediterranean beaches will vanish as water levels rise. Sahara desert could move northwards, even as far as Spain. Heavy storms not only threaten southern USA, but also the insurance companies in the area face bankruptcy.

31. 08/27/10 06:16 Below are a list of things that could be done to try to tackle global warming. Switch off lights & appliances Taxes on high polluting industries Choose energy efficient appliances Sign up to the Kyoto Protocol Recycle Use less fossil fuels and more renewable energy sources Use energy efficient transport Car sharing Improved public transport Higher taxes on polluting cars Grants for businesses that have clean policies Energy efficient light bulbs Offset carbon emissions Local Holidays

33. How else can we preserve resources and reduce pollution? 08/27/10 06:16 Resource Substitution This is where you use one product in place of another one. For example using aluminium instead of tin cans as it is cheaper and easier to recycle. Recycling Recovery of waste products by converting them into materials that can be used again. For example glass bottles, aluminium cans (only uses 5% of energy it takes to make them from scratch) Energy Efficiency Measures to reduce heat and energy loss. Individually this means switching off lights, using low energy light bulbs, insulating our homes. Also government has introduced building regulations and energy efficiency ratings on electrical products, more energy efficient cars – car in Europe is on average 90% cleaner than 10 years ago. Reducing Pollution Measures to stop emission reaching atmosphere or cleaning the emissions before they do. For example. fitting giant scrubbers on coal power stations, trying to switch from coal to gas power stations and fitting catalytic converters to cars. Alternative Energy Sources Energy sources that can be used instead of fossil fuels. These can include nuclear or renewable sources such as wind or solar.
