I have been in the IT and 3D-creative business since around 1990. I am IT entrepreneur and Consultant, book author and keynote speaker for Game changing technologies. My aim is to offer guidance for our civilization how to qualify for the 22nd century by our actions today. After understanding the urgency of the climate crisis in 2019 I started my engagement in various climate action initiatives and founded ClimateHackerz.com with the mission: Transformation into a climate positive civilization with utmost urgency. Kate Raworth's book Doughnut economics is a great framework for our transformation into a climate positive, sustainable and healthy civilization and circular economy and society.
