Geography notes

Arctic on the edgeExplain the levels of biodiversity found in the Arctic
• Extremely cold because of latitude
• Only a few animals survive the climate – endemic species
• Lack of sunlight and plants means there is a low amount of energy in the food web. This energy can’t support many species.
• Low precipitation in the polar desert.
• Geographical isolation and hostile climate.
• Altitude
• Lack of decomposition as the cold weather is unsuitable for microorganisms. Therefore, there are low nutrient levels in the soil.Study Figure 9. Evaluate the contribution these options could make to a sustainable future in the Arctic.
-OR-
Examine the possible actions shown in Figure 9
• Intro: Explain what a sustainable option is and what determines its level of sustainability.Assess the role of different players in determining the level of biodiversity in the future of the Arctic
• Locals ??Same – to continue hunting
• Oil companies ??Reduced – to exploit resources
• Arctic Council ??Reduced – to exploit resources
• UN ??Same – to maintain biodiversity
• NGOs ??Increased/Same
