This has created a massive electronic waste issue, which is the largest growing stream of solid waste in the world.

Because of the diseases it spreads, we have learned to distance ourselves from our waste, but the long line of engineering marvels we’ve created to do so - from Roman sewage systems and medieval latrines to the immense, computerized treatment plants we use today - has also done considerable damage to the Earth’s ecology. Now scientists tell us: We’ve been wasting our waste.

The sky has always held significance for humanity, in both cultural and scientific terms. And yet we persistently pollute it with sometimes unnecessary light in our obsessive desire to chase away the darkness. This effectively switches off the stars, hampering our ability to enjoy one of the most inspiring sights nature has to offer to humankind. In addition, too much light is hazardous to both our health and that of the fauna and flora of this planet.

Wenn Europas Autobauer überleben wollen, müssen sie sich radikal umstrukturieren - sowohl mental als auch real. Ex-Audi-Vorstand Peter Mertens ist überzeugt: Zukunftsfähig sind nur die Unternehmen, die mehr Nachhaltigkeit wagen, die sich stark machen für mehr europäische Souveränität in der globalen Automotive Industrie und sich öffnen für Kooperationen innerhalb und außerhalb der Branche.

Unsere Mobilität ist im radikalen Umbruch. Elektromobilität zieht in unseren Alltag ein, wir teilen unsere Fahrzeuge und Fahrten, lassen uns auf der App die besten Fahrwege anzeigen, springen vom Scooter in die Bahn und ins Auto und testen die ersten autonom gefahrenen Meter. Wir erfinden Mobilität neu - überall auf der Welt. Mobilität ist aber noch viel mehr als die Frage: "Wie komme ich von A nach B?" Sie ist ein menschliches Grundbedürfnis, der Ausdruck unserer Bewegungsfreiheit in unserer demokratischen Gesellschaftsordnung.
