Sorry about the other tangent.

Rebuilding the society from scratch is very utopic. Everyone stopping to eat meat, or at least reducing it consumption to once a week is a very realistic action plan. It only requires individual willingness and action. Given how current agriculture works, everyone switching to a "meat once a week" diet will completely solve all the draught problems. It will also cut down greenhouse effect by 20% or so (methane bad, kids). There is a very realistic action to climate change, that doesn't require any sort of revolution. But hey, I'm sure Pepsi is to blame for this not happening.

Now, where I live it's also very realistic to cycle everywhere. And it's not Ford or Volkswagen who are to blame that almost no one does.
