Constraints

• Global: the problems are at a planetary level and urgent, we cannot hope that a local solution (such as seeking autonomy and reducing ecological footprint) will be replicated globally because it implies a cooperative and benevolent spirit that is far from the current reality.
• Deep: the problems are multiple, a solution cannot solve all these problems if it does not address their root cause, and therefore it must be profound.
• Pragmatic: for example, we should not count on convincing people through long explanations and reasoning, nor on a massive goodwill. We can only count on a small proportion of good will and an even smaller proportion of good will effectively investing in building a project. On the other hand, we can very well count on short-term personal interest.
• Locally beneficial: We cannot deploy a global solution without first testing it on smaller scales. The smaller the operating scale, the more convincing it can be, as it becomes easier to understand its effectiveness.
• Progressive: Making sudden changes is risky, does not allow for prior testing and improvement, and encounters many (and rightly so) resistances.
