What is the biggest threat facing Canada in the next 50 years?

I think one of the biggest threats to any nation, even democratic countries such as Canada, is internet censorship.  I was very disturbed by the SOPA and PIPA bills that were in consideration earlier this year, even though they were only applicable in the United States.  Even more concerning was ACTA, which would've operated in the United States.  Luckily, none of these came to pass, but countries around the world are still faced with censorship every day.

Of course, my love for the internet is likely a generational thing.  I grew up with it, and it has become one of my primary means of communication.  Most importantly, I think the internet is a great way to spread information and show different opinions.  For example, the Kony 2012 campaign, despite how ineffectual it ended up being, could not have become as well known if not for the internet.  The internet is also a way to show support for a topic.  One has to look no further than Facebook to see support and activist groups with millions of members.  People even sign petitions and organise demonstrations online.  The internet is the easiest and most expansive way to receive knowledge, but is becoming increasingly more important in organising people and spreading awareness for equal rights and freedom.
