  1. Monday 4th July 2011 Objectives: - To understand the global and local factors that threaten biodiversity. - To appreciate the link between economic development and ecosystem destruction. Disruption of Ecosystem Processes The Cassowary

  2. Objectives: - To understand the global and local factors that threaten biodiversity. - To appreciate the link between economic development and ecosystem destruction. Starter 2. The cassowary 1. The dodo The Great Barrier Reef – a natural World Heritage Site. What is a World Heritage Site? Name some examples of naturalWorld Heritage Sites. What criteria would you use to decide what makes a natural World Heritage Site? [Compare your list of criteria to those on pg. 106 of the A2 Book]

  3. Objectives:- - To understand the global and local factors that threaten biodiversity. - To appreciate the link between economic development and ecosystem destruction.

  4. Objectives: - To understand the global and local factors that threaten biodiversity. - To appreciate the link between economic development and ecosystem destruction.

  5. Objectives:- - To understand the global and local factors that threaten biodiversity. - To appreciate the link between economic development and ecosystem destruction.

  6. Objectives: - To understand the global and local factors that threaten biodiversity. - To appreciate the link between economic development and ecosystem destruction. • 1] Teacher led notes on the following: • Factors that threaten biodiversity (global & local). • Movement of species. • Nutrient overload. • Economic development and ecosystem degradation. 2] Student Activities focussed on the case study: ‘The Daintree rainforest.’ Read pg.’s 106 to 109 in the A2 textbook and complete the following activities: 1. Why is the cassowary vital to the rainforest ecosystem? 2. Give THREE facts about The Wet Tropics. 3.Bullet point seven key facts that make the Daintree rainforest so important. 4. Briefly describe the climate, vegetation and soils of tropical rainforests. 5. What is leaching? 6. Complete Qu. 3ab (pg. 109).

  7. Forested Areas of Australia Daintree Rainforest

  8. Daintree Rainforest • Located at 16 S / 145 E • The Daintree Rainforest has a history that stretches more than 135 million years. • The Kuku Yalariji people, are believed to have inhabited the rainforest for more than 9000 years. • Added to the World Heritage List in 1988

  9. Benefits of the rainforests (ecosystem services) • Carbon sequestration – regulating climate • Tourism – economy support and biome protection • Medicine – 25% drugs contain products from rainforests (malaria, arthritis, diabetes). Some Daintree plants seem to be anti-cancerous • Logging – industry development from 1930s-1980s • Culture – aboriginals of the wet tropic rainforests believe that the biome is their living cultural landscape

  10. What’s the big deal? Seven key facts that make the Daintree rainforest so important: • Highest level of endemic species in Australia • 13 species of bird found no-where else • Over 65% of Australia’s butterflies and bats • 28/36 mangrove species • Example of major stages in evolution • Home to dinosaurs • Home to the deadly idiot fruit

  11. Objectives: - To understand the global and local factors that threaten biodiversity. - To appreciate the link between economic development and ecosystem destruction. VIDEO EXERCISE Watch the BBC documentary ‘The State of the Planet – Is there a Crisis?’Take notes on the scientific evidence that suggests that many of the world’s ecosystems are in crisis. http://www.youtube.com/user/MartianSanta

  12. EXTENSION: Conflict of Interest Match up the viewpoint with the correct player - cut out, stick in and add to your notes.

  13. Objectives: - To understand the global and local factors that threaten biodiversity. - To appreciate the link between economic development and ecosystem destruction. ASSIGNMENT In order to assess threats to biodiversity it is necessary to audit the damage and destruction to them. Fill in the Table ‘Systems to assess threats to biodiversity’ using the websites provided. [Submit: Monday 11th July 2011]

  14. Objectives: - To understand the global and local factors that threaten biodiversity. - To appreciate the link between economic development and ecosystem destruction. Plenary “The main threats to biodiversity are ………………….” Go around class in turn, adding information without hesitation, repetition or deviation.

  15. Objectives:- - To understand the global and local factors that threaten biodiversity. - To appreciate the link between economic development and ecosystem destruction.
