TASK 1Complete the consequences grid.

Make sure you explain the reason for the impact and the further consequences that it will have.

TASK 2Complete the past paper question

Challenge Questions1. 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?

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
