If we can change our food growing habits and local gardners and backyare growers can be supported to do just that, then we have a chance. The thing is we are just as susceptible to our crops being utterly decimated by insects, heat, cold, whatever - so we must rely on communities to sustain us going forward. And when those communities are fractured, then we have a problem.
I think what you call rutabaga we call swede? My favourite!
