     What is sustainability? What characterizes the sustainable consumption of a resource? And what specifically applies to a sustainable consumption of the resource software? In this chapter we elaborate how software has become a resource of modern societies (<a href="#software-as-a-resource-of-modern-societies">1.1</a>) and how to preserve a contemporary software resource for the future (<a href="#about-the-sustainability-of-free-software">1.2</a>). We briefly examine the influence of different licence models (<a href="#designing-a-resource-free-licenses-and-copyleft">1.3</a>) to further elaborate on of the potential of saving the last copy of a resource (<a href="#conservation-and-loss-of-resources-a-question-of-reproducibility">1.4</a>) and the sustainable use of a resource called brainpower (<a href="#sustainable-use-of-the-resource-brainpower">1.5</a>).

       In <a href="#software-as-a-resource-of-modern-societies">chapter 1.1</a>, the widest possible distribution of software as a way of obtaining the same resource was carried out as one possible solution in a theoretical mind game. However, this approach seems very uncontrollable and unpredictable and more like a game of chance because what do all free distribution methods help if - in another theoretical mind game - in the end all users decide to delete this particular software? Also it seems unpractical since the widespread use of software might be indeed helpful for keeping it available for the future, but it is not absolutely necessary. <strong>In fact, for the sustainable consumption of software as a resource and its future availability, today's distribution or basic amount of the resource does not play a decisive role, but rather its timeless reproducibility.</strong> Because as long as at least the basic set 1 – including its unlimited reproducibility – is retained under a free licence – in the best case including its documentation, language, built-tools and corresponding hardware or emulators –, it is theoretically always possible for future generations to create and distribute any number of copies from this basic set at any time. <strong>For reproducibility, it is therefore particularly important to prevent the “loss of the last copy”. </strong>
