There are a few web sites that I've come across lately that I feel are highly worth mentioning:
http://www.3rdworldfarmer.com/ is a free simulation game in which you farm animals and/or crops that are subject to drought, theft, and other situations that can leave your family forced to find outside work or with no food, medicine, or a chance of having an education. A mere glimpse of what living in the "Third World" is like.
www.freerice.com is a site where you can play to increase your word power and also, for each correct answer, you earn rice to be given to the poor by advertisers to the site.
Canadian Association of Food Banks. Hunger is also a problem in your area. Next time you go shopping, please remember to buy a few extra items to give to the food bank on your way out of the store. :-)
