The majority of the following video shows a bit of the bad-side of America. The main points made are about why America shouldn't increase immigration, and it'll upset the balance of their country, and that wouldn't be good for them.
However, halfway through the talk, the speaker uses 'gumballs' to give an illustration about how much America need to do about 3rd world poverty. It's a pretty good demonstration of how much population increase is happening.. yet the numbers today are even greater than when the video is published.
I do not endorse these guys views on immigration or anything else, what I do want to look at though is the little gumball example, and wonder if you should be doing a little bit more to help the majority of the world living in poverty.
