Excellent discussion here, with much food for thought. Transition certainly recognizes that our economic systems are unsustainable and must transition to something else. What that something else is is for all of us to figure out as we go through this process.
I don't think the problem is 'profit' so much as an obsession with growth. Growth is perfectly natural for young systems in nature, but at a certain point it can become suicidal. I think we all agree that exponential growth at some point is not sustainable on a planet with finite resources (ancient sunlight) and a limited supply of 1 renewable resource (current sunlight).
We have to break out of this mentality and begin demanding that all resources on this planet belong to everyone, not just the corporations who bribe and blackmail governments into allowing them to hold the rest of the planet hostage while they control the supply. In effect, planting a garden is one of the best things you can do - you're telling Monsanto for example, that you're not going to keep buying their poisonous "food". Bravo. Likewise, if you ride a bike you're telling the oil companies you're not going to contribute to their power hold; and perhaps most importantly, if you stop spending money (or in most people's cases, borrowing it) you're sending a message with your actions that you're not going to support a system that exploits the many for the benefit of very few.
There aren't endless sources of energy?! I hate to keep quoting the Zeitgeist Orientation Guide but this research has been done and proves quite the contrary. Let's not be making statements that simply ignore reality, that gets us nowhere except perhaps deluded. ...I feel like people are making assertions without really understanding the science or facts required to make such assertions. Since this is probably the third time I've cited the Zeitgeist Orientation Guide perhaps some of you out there would care to read it - most of what we're talking about has been heavily addressed and accounted for already...
...I certainly respect everyone's opinion out there but there are facts that are not based on opinion, they're facts - and those facts must be treated as such.
