Ecosystems work by Sergio Gutierrez Fernandez

  1. 1. -When the plants or animals die, they rot away and decompose due to the action of fungi and bacteria. This releases the nutrients which are returned to the soil ready to be used again.
  2. 2. A deciduous woodland can be divided into three main layers -Canopy: tallest trees: oak, beech -Shrub: Tall trees: ash, birch, sycamore Smaller trees/tall shrubs: holly, hazel, hawthorn -Ground: Brambles, bracken, ferns, grasses, wildflowers Thick layer of decaying leaves
  3. 3. Characteristics of tropical rainforests
  4. 4. It is a method of farming. There are groups of people clearing just enough land on which to grow crops for their small community. Often, in places like the Amazon forest, the land rapidly become infertile and the people had to move and make a new clearing, allowing the forests to reestablish itself
  5. 5. Where savanna grassland vegetation? Characteristics of savanna grassland
  6. 6. Definition of coniferous forests Coniferous forest: Where?
  7. 7. Variety of animals and plants in coniferous forests
  8. 8. Acid rain is caused by…
  9. 9. Acid rain: effects -Burn less fossil fuels by conserving energy -Use non-fossil fuels such as nuclear energy, or power from the wind or sun -Remove sulphur from coal before burning -Use new, more efficient boilers in power stations -Remove sulphur from waste gases -Reduce car emissions by using unleaded petrol
  10. 10. Deforestation is not only losing resources, it is also changing world climates: -The burning of the rainforests, and the release of carbon dioxide is a major cause of global warming -A greatly reduced number of trees will mean a decrease in evapotranspiration. Some scientists believe this could eventually turn places like the Amazon Basin into desert -Nearly one-half of the world’s supply of oxygen comes from trees in the Amazon Basin. It takes one large tree to provide enough oxygen for two people for one day, and 150 large trees to absorb the carbon dioxide produced by one small car
  11. 11. There are three extreme conflicts of interests in the rainforest:
  12. 12. What can be done to prevent or reduce soil erosion?
  13. 13. Causes of desertification -They result from a combination of climatic changes (decreased rainfall and global warming), and increased human activity and pressure upon the land (overgrazing, overcultivation and deforestation).
  14. 14. Population
  15. 15. Birth rate, infant mortality rate, population growth, life expectancy comparing developing countries and developed countries
  16. 16. The population of the United Kingdom seems to have a true pyramidal shape?
  17. 17. After the problem, the solution proposed was
  18. 18. International migrants include…
  19. 19. How does migration affect different countries? *Advantages: -Overcomes labour shortage -Prepared to do dirty, unskilled jobs -Cultural advantages and links -Some highly skilled migrants -In a developing country these migrants could increase the number of skilled workers -Reduces pressure on jobs and resources (food) -Loses people of child-bearing age, causing a decline in the often high birth rate -Migrants develop new skills which they may bring back to their home country -Money earned may be sent back to their home country *Disadvantages -Immigrants are most likely to be the first unemployed in a recession -Low-quality, overcrowded housing lacking in basic amenities (inner city slums – bidonvilles in France) -Ethnic groups tend not to integrate – racial tension -Limited skills/education, language difficulties -Lack of opportunities to practice own religion, culture, etc -Loses people in the working-age group -Loses people mostly likely to have some education and skills -Left with and elderly population and so a high death rate -Increasing dependency on money sent home by the workers
  20. 20. Is there a hierarchy of shopping centres of different sizes?
  21. 21. Factors of deprivation
  22. 22. Why have CBDs changed? -The increase in traffic congestion led to several shops moving to out-of-town locations -Hypermarkets and out-of-town shopping centre led to a decline in the number of shoppers visiting the city centre -The decline in the number of shoppers has continued with the increase of internet shopping -People visiting the city centre wanted a safer environment -Increasing demand for leisure amenities (entertainment) -Many taller buildings were built in order to offset the costly rates and rent resulting from the high land values
  23. 23. The London Docklands Development Corporation: Tasks -To improve social conditions (new housing, amenities) -To improve economic conditions (new jobs, transport system) -To improve environmental conditions (cleaning up the docks, planting trees, open spaces)
  24. 24. Advantages of the rural-urban fringe -A pleasant environment with more open space -Less traffic congestion and pollution (air and noise) -Cheaper land -Easier access and a better road infrastructure
  25. 25. -Housing development -Science and business parks -Hypermarkets, superstores -Firms -Hotels and conference centres -Road development -Recreational areas such as country parks and new sports stadiums
  26. 26. -The result of the counter-urbanization village is known as…, because…
  27. 27. What are the damaging effects of traffic?
