Gummi
Der flexible Alleskönner
Heutzutage einen Industriezweig zu finden, der ohne Gummi auskommt, ist denkbar schwierig. In dieser Folge gehen Joey Grit Winkler und Fero Andersen der Frage nach: Was ist Gummi eigentlich und wie wird er hergestellt? Die unentbehrliche Grundlage für Gummi ist Kautschuk, der weiße Saft des Kautschukbaumes. Dieser Baum kam ursprünglich nur in Südamerika vor und so waren es alte, südamerikanische Hochkulturen, die vor über 800 Jahren Kautschuk nutzbar machten, indem sie ihn zu einem Ball formten, um einem rituellen Ballspiel nachgehen zu können. Auch heute ist Kautschuk die Grundlage schlechthin für Gummi. Kautschukbäume werden allerdings nicht mehr nur in Südamerika, sondern in tropischen Gebieten rund um den Globus angebaut: Die Nachfrage nach Gummi auf dem Weltmarkt ist enorm.

Blogging
The weblog or blog, for short, as a medium is not much older than this century. Blogs came into being in the World Wide Web as ’messages from below’, as web pages from web creators who wanted to share their view of the world with the world. They are short notes, long texts, pictures, videos, which are posted loosely and at random intervals to the world for an undefined public.
