Well there's lots of ways you could answer it, so take what I say with a grain of salt.
The economic implications are pretty straightforward.
- sick people/people who become ill earlier can't work.
- diabetes is associated with several different diseases. You should look them up.
- treatment can become very expensive when it's not controlled properly.
- type 2 diabetes used to be associated with older age groups, but it's becoming an issue for even teenagers these days. More and more people need to be treated under a national healthcare system (i think that's what canada has?).
- money is being ''wasted'' on a potentially avoidable disease. Should money be spent on educating school children to eat properly, since they are clearly not being taught by their parents?
The political implications can probably be an essay of its own.
- we have the NHS. Some people feel that the obese should pay for their own healthcare because it's ''unfair''. With the increasing burden on a national healthcare system, more and more people will be calling for this (along with smokers and alcoholics).
- society may begin descriminating against fat people, as the problem worsens.
- increasing gap between the rich and poor.
- should businesses be punished? In England there's been several laws passed to encourage healthy eating. This includes the introduction of the traffic light system and junk food advertisements being banned from daytime TV.
- an increasing rate of diabetes is an indicator of several other problems. If the population isn't looking after itself, there will be a point where life expectancy begins to fall.
Yeah.... you get the idea lol. Someone will probably say I've written a load of rubbish

Hope it helps a bit though
