Permaculture has a very positive image as a solution to the need for perpetual growth, and this might be put at risk if it became associated with any deliberate attempt to cause system failure. While I understand why Holmgren would open a discussion on this front, given what is at stake, it is indeed dangerous to ‘grasp the third rail’ in this way.
Permaculture should be a major building-block of any kind of system reboot following the operating system crash that a financial crisis represents. After all, once we navigate that period of artificial scarcity, we will have to address the real scarcity inherent in looming resource limits....
We need to get down to the business of doing the things on the ground that matter, and to look after our own local reality. We can expect considerable opposition from those who have long benefited from the status quo, but if enough people are involved, change can become unstoppable. It won’t solve our problems in the sense of allowing us to continue any kind of business as usual scenario, and it won’t prevent us from having to address the consequences of overshoot, but a goal to move us through the coming bottleneck with a minimum amount of suffering is worth striving for.
