All but the last of those questions were asked in my Biology class last year.
I don't know if it was because I watched one too many Doomsday preppers, or my natural paranoia, but my 'end game' is to have a virtually self- sufficient farm, maybe selling a few things here and there to support animal rescues.
Fast food isn't jsut because people are lazy- they don't know how to cook. I'm in a 'healthy cooking' class at school, and there are 5 groups. Only 3 were able to make a simple recipie without any issues. About 10 people didn't know what zuccini were, and 3 didn't know what flour was. Half the class didn't know how to make a baked potato. Almost 3/4 didn't know how to grate cheese. I could go on. And these are high school students.
