I believe that neither man, nor chicken can be sustainably kept in battery farming conditions……in the case of chickens of course this is not the goal. In the case of man, I suppose it’s debatable in today’s world whether sustainability in resource mgmt is a goal or not. And while I am a bit off the gardening topic I’m in a related field: animal husbandry.
If you don’t know what I am talking about, check online for a photograph of battery held chickens, print a photo and take it to your cubicle and have a look around. And If you are in a nice office with a view of the outdoors then be really sure to enjoy it 🙂
Remember, being outside is good for you!
