A

Most water is stored as ice

24
Q

Plants

A

Compact, short growing( avoid the permafrost and make the summer surface thaw) slow growing to avoid the wind

25
Wakenham Bay, Quebec N Canada
Ocean food Mussels Tide changes 2x a day Mussels are a rich source of mineral and vitamins Harvested in caves created by blocks of ice leaning together when the ice hits the sea bed
26
Qaanaaq, N Greenland
Inuit people Hunters of marine animals ( narwhal) Rich source of vitamin c Summer months = hunters camp on the edge of the sea ice and travel in kayaks to catch their prey using harpoons Maktaqq - vitamin c
27
Barrow, Alaska
Whale hunting - important aspect of life for Inuit people despite access to food shops Bowhead whales - pass the coast 2 x a year Whale meat is an essential part of their diet most people eat it 2 x a week Whale oil is added to caribou
28
Extreme environmental conditions support
Low species diversity and delicate food webs Ecosystems are vulnerable to change Future of food being harvested from their is declining due to diminishing ice With indigenous people largely dependent on it, there food security is threatened
29
Hunting terrain, migration patterns, quantity and quality of traditional food sources
Affected by cc Slushy ice - cannot hunt on Travel routes are made longer, more dangerous and unpredictable Polar bears and walrus eating moss on land - disrupts the food supply Fish stocks decreased and are invaded by warm water species Herding is delayed as the lake they cross is not freezing Caribou born - missed peak foliage availability - many do not survive
30
Wild resources declining
Pollution and contamination Contaminations are showing up in animals, fish and waters of the Arctic People are turning to store brought food, increasing social problems of increased prices ( remoteness and low budgets and low income with limited Job opps , obesity, malnutrition, health issues
