Collective intelligence, global commons and copyright

It's time to connect the discussions on global commons and copyright. The questions are: What is private and what not? What should be private and what not? The ocean? An idea? An invention? What is authorship in the world of the 21st century? What helps to develop the necessary degree of global collective intelligence in order to find solutions for problems like water supply, climate change, poverty etc. Whatkind of private and/or collective ownership fosters creativity and innovation? A first place to discuss all this could be global-commons.org.
