Question

If you get a chance to live in the polar region, what type of problems would you face? Mention any 2

Answer 1

Explanation:

Potential challenges – climate change

1 Stock management in the event of climate warming / cooling – effects on nomadic lifestyles, social outcomes. 2 Economic, education, issues in cold climate conditions. 3 Sea warming – invasion of other species colonization, effects on indigenous species.

Answer 2

1 - Climate change / Global warming, resulting in a warming of the sea and loss of sea ice and land-based ice, this is greatest long-term threat to the region. Already some ice shelves have collapsed and ice slopes and glaciers have retreated. Oceanic acidification (from extra dissolved carbon dioxide) is already leading to the loss of some marine snails thought to have a significant part to play in the oceanic carbon cycle. The breeding populations and ranges of some penguin species have been altered.

2- Fishing, both legal and illegal. The world's oceans are over-fished, the chances are that if investments into the kinds of boats and fishing gear needed for Antarctica are made, then it too will suffer this same fate. Fishing for krill could be particularly significant as these are at the bottom of many Antarctic food chains. There are already illegal fishing boats that ignore current regulations.
