Managing Resources Revision Cards - What is a resource

1. Managing Resources Revision Cards - What is a resource? A resource is anything that can be used by humans for their advantage. Resources are widely used to make our lives better and easier.

2. Renewable/Non-renewable If a resource is classified as Renewable then it can be reused and is classed as Sustainable e.g. Solar Power. If it is classed as Non-renewable then when it is used it is gone forever e.g. Fossil Fuels. In other words these resources are Finite.

3. Generating Electricity Generating electricity falls into two types, Renewable and Non-renewable. Non-Renewable methods � Fossil fuels (Coal, Oil and Gas), Nuclear Power, Trees. Renewable methods � Solar, Wind power, tidal power, Hydro Electric Power (HEP), Biomass, Trees (if managed) and Geothermal. We use these fuels to create energy.

4. Wind Farms Wind farms require a large open space. They need to be on high ground and away from areas of population. They need to be in areas of strong stable wind. They are being built offshore aswell as on land. An example is Lambrigg in the Lake District.

5. Advantages/Disadvantages of Non-renewable methods Advantages � Cheap, readily available, proven technology, generates a large amount of electricity, popular with LEDC�s. Disadvantages � Creates a lot of pollution e.g. CO2 and SO2, it is non-renewable, it is running out, linked to the greenhouse effect and global warming.

6. Advantages/Disadvantages of Renewable methods Advantages � Clean, renewable, sustainable, becoming increasingly popular with MEDC�s. Disadvantages � Unreliable, doesn�t generate a lot of electricity, very expensive, complex technology.

7. The future of generating electricity The use of Nuclear Power is growing, especially in the UK. The use of renewable methods is also growing, mainly in MEDC�s as it is expensive. Both are very controversial and can cause arguments.

8. Energy Demand The amount of energy used has massively increased due to various reasons. These include � more electrical gadgets, more cars, more people. As more LEDC�s industrialise, the amount of energy used will continue to soar.

9. Using Resources We need to practice good Stewardship � This is where we use our remaining resources sensibly and carefully. An idea is to practice Resource Substitution where we use other materials instead of those materials which are running out. The other option is Recycling. This is becoming increasingly popular.

10. Pollution The use of resources creates a lot of pollution, particularly when fossil fuels are burnt to create electricity. This causes acid rain, ozone destruction, has been linked to making the greenhouse effect worse and causing global warming.

11. Acid Rain This is caused when pollution e.g. SO2, CO2, NOx (Nitrogen Oxides) mixes with rain water making it more acidic. This pollution comes from cars, factories, power stations and houses. This kills forests, lakes, erodes buildings and destroys crops. The solutions are reducing pollution, putting lime in lakes and cleaning up factories. The acid rain created in the UK often falls in Sweden and Germany.

12. The Greenhouse Effect This is where the Earth�s atmosphere acts as a Greenhouse trapping some of the Sun�s energy and reflecting it back onto the Earth. This will heat the Earth up. This is a natural process. It is believed that the pollution caused by humans is making this process stronger and more and more heat is being trapped. Some scientists believe that this is the cause of Global Warming.

13. Global Warming Global Warming is the rise in the average temperature across the Earth. The average Earth temperature has increased over the last few years. This could be caused by a number of factors. It could be human caused from pollution, it could be natural. It could be a natural cycle of warming, it could be due to changes in the Earth�s orbit of the Sun. No-one knows for sure.

14. Effects of Global Warming Severe weather, higher global temperatures, ice caps melting leading to sea level rise and loss of low lying land e.g. The Maldives, loss of animals e.g. Polar Bears, drought and forest fires.

15. Responses to Global Warming Whatever the causes of Global Warming, we can respond to it by reducing the pollution we cause. Use energy saving light bulbs, recycle more, turn our heating down, turn lights off, use fewer cars

16. Tourism Tourism is where people travel away from their homes for leisure and pleasure. This is a growing industry. People are doing more and more things during their leisure time leading to the growth of many leisure facilities e.g. Golf courses, shopping centres and coastal resorts.

17. The Growth of Tourism Tourism has rapidly grown in the last 30 years. This is due to many reasons such as the development of planes, more time off work, cheaper holidays, package holidays, higher wages, more disposable income. People are travelling further than before, the most popular destination for British tourists is Spain.

18. Advantages/Disadvantages of Tourism Advantages � Brings in money for local economy, provides jobs, can help improve the local infrastructure (roads and services). Disadvantages � Causes pollution (e.g. planes � linked to global warming), causes erosion of footpaths, litter, overcrowding, traffic congestion, drunken tourists, violence, culture clashes, local customs can be exploited.

19. Conflicts caused by Tourism Tourists can conflict with both each other and the local people. The activities they do conflict with one another. For example water skiing will conflict with fishing. The Goldfish Bowl effect is where tourists will stare into peoples houses causing them distress.

20. Tourism Recap

21. Tourism in the Lake District National Park The Lake District National Park is in the North-West of England. People go there to go walking, enjoy the peace and quiet, go boating and other water based activities. The problems caused by the tourists here are footpath erosion, overcrowding, pollution, goldfish bowl effect and litter.

22. Tourism in Kenya People travel to Kenya to mainly go on safari to see wild animals such as the Lion and Cheetah. They also go there to see the coral reefs off Kenya�s East coast. Advantages - Tourism has brought a lot of money into Kenya and provided many jobs and encouraged the improvement of much of the infrastructure. Disadvantages � Conflicts between tourists and the Masai people, damage to the coral reefs by boat anchors, soil erosion from vehicles, poaching, animals get disturbed by the vehicles. Solutions � Encouragement of Ecotourism

23. Sustainable Tourism

24. Ecotourism Ecotourism is tourism that does not harm the local environment that is being visited, it is sustainable. It is the same as Green tourism. It is becoming more and more popular. People are encouraged to enjoy and look at the place they are visiting and not just lie on the beach. They often involve helping out, e.g. doing animal studies for scientists. The impact to the local people and environment is kept to a minimum.
