Your pictures were horrible quality. It definitely made your submission look more like a joke than a serious submission. You don't need to fill up the window if we can't make out the pixels.
I actually did a project on this a while ago, with the imbalanced diets and stuff. I'm also working on a project based on Afghanistan right now.
However, you could have put a little more effort and care into it, not just a pile of huge pixels that we can't make out. I agree with you, but not all Americans are overweight. I know plenty of healthy Americans. Just because they have a larger proportion of overweight people does not mean the entire nation is overweight. You're making a lot of generalizations.
Anyways, I'm Canadian, so in addition to my not complying with your generalizations, I'm also racially exempt from them. If anyone says that Canadians and Americans are the same, they're wrong and deserve to be tortured in some way for their ignorance. We're similar, but not identical.
