Food.

Food is a major part of life.  Yet we don't really care where it comes from or how it's made.  People are starting to care and think about it but do we really need to have someone tell us that we need to pay attention to what we put in our body?  I've seen parents argue about training wheels for their kid's bike yet they have no problem giving the same kid whatever junk food is nearby.

A lot of people might not know that grocery stores as we know them are a pretty recent development.  My grandparents were born around the turn of the 20th century and they would be amazed with what is in grocery stores now.  The farmer side of them would be sad that farms are still a bitch and a half to work but the farmer side would also be amazed with aqua and hydroponics.  Below ground greenhouses and gmo products and Kobe beef; all new to them.  Some good, some they might not be too thrilled about.  People raising a stink about if the chicken was fed organic produce; of course it was fed organic feed and scraps I can't afford anything else.  They were poor farmers.  My father says that the former slaves down the road had more money than his family because they had beef cattle while his family raised chickens. 

I've heard some foodies and slow food movement people talk about how we need to appreciate the soil again.  I definitely believe that.  I also think we need to respect and appreciate our bodies just as much.
