We've explored a whole range of topics, from the impact of climate change on the polar regions, to the issues of pollution and resource exploitation, to the consequences of polar tourism. What's struck me is how differently the Arctic and Antarctic regions have responded to some of these impacts (for example, sea ice is disappearing in the north, but expanding in some areas of the Antarctic). Of course, there are many similarities between the regions too, such as their vulnerability to pollution.
I've also found it interesting how some of the human impacts link together. For example, melting Arctic sea ice has led to increased opportunities for oil drilling (and therefore potential pollution issues) and tourism.
I hope that you've enjoyed reading my blog, and that you've learnt something about the way in which humanity is impacting upon the polar regions. If nothing else, maybe it's helped you to answer more questions on University Challenge than usual (an added bonus, I've found). Above all, hopefully it's inspired you to find out more about the polar regions and their relationship with mankind. After all, this may be the end of my blog (for now!), but many of the issues we've discussed are only going to become more prominent in the future.
So, I'll say goodbye for the moment, and leave you with this video. It shows why the polar regions need to be protected, highlighting their importance as a habitat for wildlife. Also, it's just plain cute.
