The document discusses the impact of increasing information and communication on society and the environment. It notes that while the amount of man-made information grows exponentially, biodiversity and some animal populations are decreasing. This leads to greater entropy in closed systems. However, information is part of the physical universe like matter and energy. As new digital communication formats emerge, like sharing videos on YouTube, interactions are changing as the next generation adopts new ways of communicating.

6. The bare minimum per person for drinking and sanitation is measured at 20 liters a day
But in Germany average is 130 liters
In the United States - between 200 and 400 liters per person per day

21. What is Information ?
• Tom Stonier: information is a part of the
physical universe the same way as matter
and energy
• Konrad Zuse, inventor of digital computer
and the first high-level programming
language:
– the whole universe is being computed by some
automaton, everything is just a computation
– nobody has yet shown any flaws in Zuse's
argument
22. Increase of Information
• Amount of man-made information grows
exponentially
• Currently we create in every two days as
much information as we did from the dawn of
civilization up until 2003
23. New communication formats
• Digital natives are abondaning glyph-based
languages and introducing new communication
formats; most often based on video
– to YouTube is uploaded every second more than
24 hours of video
– in Feb 2011 MIT Press released Learning From
YouTube - a free online-only "video book“- peer-
reviewed with an ISBN number
