2 What are the environmental, social and economic consequences of deforestation? List as many as you can on different post it notes

3 What are the environmental, social and economic consequences of deforestation? Learning Outcomes: Describe and explain the following consequences. Loss of resources and trade Loss of species diversity Loss of carbon reservoir Changes to local climate Loss of tourism and recreation.

4 Watch the second clip and write down why clearing the forest might affect the whole world Watch the clip and write down 3 ways in which you think the local environment has been damaged.

5 What are the impacts of deforestation on the nutrient cycle? TASK Redraw this and label it to show what happens when the trees are removed. What are the impacts of forest removal in the Amazon?

6 Write this into your book in your own preferred learning style

7 Task – Read the flow chart then fill in your version showing what will happen after the trees are cut down. Remember to aim for opposites! Pick from Very few leaves dropped Little vegetation growth Nutrients don’t stay in soil but are washed out (leaching) Not many nutrients in soil Infertile soils

10 TASK 1 Complete the consequences grid. Make sure you explain the reason for the impact and the further consequences that it will have. TASK 2 Complete the past paper question

11 Challenge Questions 1. What is the Forest Stewardship Council and how does it encourage the sustainable use of forests? 2. Why is it a contradiction that MEDCs criticise LEDCs for wanting to exploit their forests?

12 What is the Forest Stewardship Council FSC = an NGO established to promote the responsible management of the world’s forests Forest owners who want FSC accreditation have to manage their forests sustainably and products marked with the FSC label should come from forests that are managed to meet the social, economic and ecological needs of present and future generations Example FSC rules: Prohibit conversion of forests or any other natural habitat Respect of international workers rights Respect of Human Rights with particular attention to indigenous peoples Prohibit the use of hazardous chemicals No corruption – follow all applicable laws Identification and appropriate management of areas that need special protection (e.g. cultural or sacred sites, habitat of endangered animals or plants Example FSC rules: Prohibit conversion of forests or any other natural habitat Respect of international workers rights Respect of Human Rights with particular attention to indigenous peoples Prohibit the use of hazardous chemicals No corruption – follow all applicable laws Identification and appropriate management of areas that need special protection (e.g. cultural or sacred sites, habitat of endangered animals or plants
