Welcome to our web page

Since 1983 I travel around the world. Since 1991 my wife Tanja accompanies me on our life project „The big journey“. As ambassador of mother earth it is our dream to create a time document of our planet. In picture, film and text we want to show how it looks on our earth today and how she changes. We want to form a compensatory pole to a world which overtakes itself every day a little bit faster. With our reports we like to serve a mosaic piece, to hold on, to find the own way, to have goals and to realise aims. And also we like to remind of how beautiful, many-sided and protection–worth our planet is. We wish you joy and inspiration on our web page.
