>I live on a farm.

Good. Now give me some of the vegetable you grow and what system you use... Dont worry, i study this things, so if you want to be specific i can understand.

>What I am calling out as extremely foolish is getting rid of farms

No one wants to get rids of farms. They are not just place to produce foods... Or at least they shouldn't. They should be a part of the society and ecosystem.

>What happens when something contaminates or corrupts the food systems? Talk about a food crisis. And that is besides the fact that the food will be extremely unhealthy and cancer causing to the human body.

This happen faaaaaar more often in uncontrolled enviroment such as Farms... Hey, did you follow all the steps to be sure your soil doesn't have an excess in N? Because that might create a build up of carcinogenic substance in vegetable... But if you stay too low the N will be removed by water being drained...

You know what could solve this problem? If the water wouldn't go away... Oh that's right, a hydroponic.
