Silke Helfrich and a few other German commoners have drafted a Commons Manifesto that explains the importance of the commons for the well-being of us and our societies. The manifesto also calls all of us to assume our responsibility and protect and nurture the commons:

Commons inspire and connect. To take them into account requires a fundamentally different approach in perception and action. Commons are based on communities that set their own rules and cultivate their skills and values. Based on these always-evolving, conflict-ridden processes, communities integrate themselves into the bigger picture. In a culture of commons, inclusion is more important than exclusion, cooperation more important than competition, autonomy more important than control. Rejecting the monopolization of information, wealth, and power gives rise to diversity again and again. Nature appears as a common wealth that must be carefully stewarded, and not an ever-available property to be exploited.
